OPINION
Plaintiff, a resident of Connecticut, initially filed the instant action against Trek Bicycle Corporation (“Trek”), a New Jersey-based company, in the Superior Court of New Jersey, Camden County, asserting claims for negligence (Count I), breach of express and implied warranty (Count II), and strict products liability (Count III) arising out of injuries allegedly sustained by Plaintiff while using a defective bicycle seat. Following Trek’s filing of a third party complaint against Defendants Vetta USA, Selle Italia, and Brunswick Corporation, companies allegedly involved in the manufacture, assembly, design and distribution of the bicycle seat at issue, Plaintiff was granted leave to file an Amended Complaint asserting his claims directly against those three additional defendants. 1 The case was subsequently removed to this Court, which has jurisdiction over Plaintiffs claims pursuant to 28 U.S.C. § 1441 and 28 U.S.C. § 1332. Currently before the Court are Defendants Trek Bicycle Corporation, Vetta USA, and Selle Italia’s respective motions for summary judgment. 2 Defendants Vetta USA and Selle Italia both seek summary judgment on the grounds that Plaintiffs claims for negligence (Count I) and strict products liability (Count III) are statutorily barred by the applicable statute of limitations. Defendant Vetta USA further moves for summary judgment on these claims on the grounds that there are no disputed issues of material fact regarding the company’s lack of involvement in the manufacturing and/or selling of the allegedly defective product. 3 Defendants Trek and Selle Ita-lia also move for summary judgment of Plaintiffs strict products liability claim (Count III) on the grounds that the proffered testimony of Plaintiffs two expert witnesses is inadmissible under Federal Rule of Evidence 702 and that, without such testimony, Plaintiff has failed, as a matter of law, to adduce sufficient proof to demonstrate a causal link between the allegedly offending bicycle seat and his inju *476 ries or that there is a danger associated with use of the bicycle seat about which Defendants had a duty to warn. Trek also moves for summary judgment on its third party claim for common law indemnification (Count II) against Co-defendant Selle Italia. 4
For the reasons set forth below, the Court will enter summary judgment with respect to Plaintiffs claims for negligence and strict liability against Defendants Selle Italia and Vetta USA, as such claims are barred, as a matter of law, by New Jersey’s two-year statute of limitations for personal injury actions. However, the Court will deny Defendant Trek’s motions for summary judgment against Plaintiff and Co-defeñdant Selle Italia.

“[Sjummary judgment is proper ‘if the pleadings, depositions, answers to interrogatories, and admissions on file, together with the affidavits, if any, show that there is no genuine issue as to any material fact and that the moving party is entitled to a judgment as a matter of law.’ ”
Celotex Corp. v. Catrett,
In deciding a motion for summary judgment, the Court must construe the facts and inferences in a light most favorable to the non-moving party.
Pollock v. American Tel. & Tel. Long Lines,
II.
Plaintiff, Joseph M. Yarchak, first joined the Willimantic, Connecticut Police Department in 1989. In 1995, he became a member of the police department’s bicycle patrol unit. (Pl.’s Dep. at 166). From June/July 1995 through the Fall of 1998, Officer Yarchak rode with the bicycle patrol unit approximately 10 to 12 miles per day, 5 days per week, for approximately 7 to 8 months a year. (Id. at 62, 64). The bicycle Officer Yarchak rode was equipped with a “Trek” seat from the time of its purchase until some point after February of 1998, when Officer Yarchack replaced the original seat with a “Biko” seat. (Id. at 49, 174). 5 Within a few months of beginning bicycle patrols in 1995, Officer Yarchak began regularly experiencing numbness and tingling in the groin area both during and immediately aftér riding the bicycle out on patrol. (Id. at 66). When these episodes occurred, he would dismount from his bicycle and walk around until the numbness subsided. The numbness or tingling would typically subside within 30 seconds to two minutes after stopping and dismounting from the bike’s saddle. (Id. at 70). Yarchak had never experienced numbness or tingling in his groin area before joining the bicycle patrol unit and attributed the numbness to his *477 extended periods of bicycle riding while on patrol. (Id. at 66; Selle Italia Br. Supp. Mot. Sum Judg. at Ex. B, p. 166-167).
In an April 22, 1997 visit with his family doctor, Dr. Ralph La Guardia, Officer Yarchak reported a couple of instances in 1997 in which he was unable to maintain an erection. (Pl.’s Br. Opp., Exhibit A, p. 73-77). He had never before experienced any symptoms of erectile dysfunction or impotence. (Id. at 75). According to Officer Yarchak’s deposition, there was no discussion during this visit regarding any possible link between his bike riding and these symptoms because, at the time, he did not yet think it was a serious problem or suspect that these symptoms might be related to the numbing or tingling sensation he often experienced while bicycle riding. (Id. at 76-77).
Over time, however, Plaintiffs condition became progressively worse. At some point just prior to September 18th, Plaintiff viewed a promotional spot for an upcoming episode of the television news show 20/20 featuring reports on, among other topics, the possible link between impotency and bicycle riding. (Id. at 82). Although he was not able to watch the original September 18th broadcast of this 20/20 episode, he viewed a tape of the program approximately “two weeks later,” either the “end of September or beginning of October” 1997. (Id.). This broadcast featured an interview with Dr. Irwin Gold-stein, a professor of urology at Boston Medical Center and a leading researcher into a possible connection between bicycle riding and sexual dysfunction. (Selle Ita-lia Br. Supp. Mot. for Sum. Judg., Exhibit B, at 80). According to Plaintiffs deposition testimony, it was this report on 20/20 that “first raised the question in [his] mind that there could possibly be a connection” between his erectile dysfunction and his bicycle riding. (Pl.s Opp. Br. at 81).
On October 21, 1997, after having viewed the program, Officer Yarchak visited Dr. La Guardia and told him about the 20/20 program, expressing concern that his erectile dysfunction may be connected to prolonged periods of bicycle riding while on patrol. Dr. La Guardia discussed with Plaintiff the possibility of a connection between his bicycle riding and his impotence, and referred him to Dr. John Graham, a local urologist, for further examination. In notes dictated on the same day as Plaintiffs visit, Dr. La Guardia opined that Plaintiff impotence may be related to “secondary pressure from the bicycle seat causing problems.” (Selle Italia’s Mot. Br. in Supp. of Mot. for Sum. Judg. at Ex. D). During a visit to Dr. Graham on November 10, 1997, Plaintiff explained that he was a bicycle policeman, that he rode his bicycle for extended periods of time, and that, based on the 20/20 episode, he was concerned about a possible link between his impotence and the bicycle riding. (Vetta U.S.A.’s Mot. Sum. Judg., Exhibit F, at 89).
On or about February 19, 1998, Plaintiff visited Dr. Irwin Goldstein at the Boston Medical Center for an initial consultation. (Pl.’s Dep. at 112). Dr. Goldstein is a professor of urology at the Boston University School of Medicine and one of the nation’s leading researchers on impotence. His ongoing research into the link between erectile dysfunction and bicycle riding was featured on the September 18, 1997 broadcast of 20/20 which originally gave rise to Plaintiffs concerns about the link between his impotency and his bicycle seat. Following his visit with Dr. Goldstein, Plaintiff replaced his Trek bicycle seat with a seat sold by Biko. (Pl.’s Opp. Br. at Exhibit A, p. 174). As Plaintiffs opposition brief explains, the Biko seat is specifically designed to distribute pressure away from the perineal arteries underneath the genitals. After switching to the Biko seat, *478 Plaintiff no longer experienced numbness or tingling in his groin area while on bicycle patrol. (Pl.’s Opp. Br. at 3). Approximately one year later, in February 1999, Dr. Goldstein conducted a diagnostic test, called an arteriogram, which, according to the doctor, revealed “specific blockage in the arteries that allow blood to flow to the penis” and confirmed a direct link between Officer Yarchak’s impotence and the seat on his police department bicycle. Surgery performed on June 1,1999 repaired Officer Yarchak’s damaged arteries and appears to have rectified his erectile dysfunction.
On March 26, 1999, Officer Yarchak filed the instant action in the Superior Court of New Jersey, Camden County, against Trek Bicycle Corporation, the New Jersey-based seller and distributor of the bicycle seat which is alleged to have been the cause of his erectile dysfunction. 6 On August 1, 2000, Trek filed a notice of motion for leave to file a Third Party Complaint against Selle Italia, Vetta USA, and Brunswick Corporation, companies allegedly involved in the distribution, manufacture, and assembly of the seat. On September 8, 2000, with leave of the Superior Court, Trek filed a Third Party Complaint against these business entities. Plaintiff thereafter filed an Amended Complaint on October 10, 2000, with the Superior Court naming Vetta USA, Selle Italia, and Brunswick Corporation as additional party defendants in this products liability action. The case was subsequently removed to the District Court of New Jersey.
III.
Defendants Selle Italia and Vetta USA have moved for summary judgment with respect to Plaintiffs claims for negligence (Count I) and strict products liability (Count III) on the grounds that such claims are barred by New Jersey’s statute of limitations. 7 New Jersey’s statute of limitations governing personal injury claims, including claims sounding in negligence and strict products liability, is found at N.J.S.A. 2A:14-2, which states:
*479 Every action at law for. an injury to the person caused by the wrongful action, neglect or default of any person within this state shall be commenced within tioo years next after the cause of action shall have accrued.
The purposes of New Jersey’s statute of limitations are two-fold: “(1) to stimulate litigants to pursue a right of action within a reasonable time so that the opposing party may have a fair opportunity to defend, thus preventing the litigation of stale claims, and (2) to penalize dilatoriness and serve as a measure of repose.”
Gantes,
Ordinarily, a cause of action accrues at the time of the alleged injury.
8
This is because, in most cases, awareness of one’s injuries is immediate and knowledge that someone is at fault is inherent in the nature of the injury or the circumstances in which it occurred. However, in order to alleviate the harsh results that might otherwise flow from a rigid or mechanical application of the statute of limitations, the New Jersey Supreme Court has devised an equitable principle known as the “discovery rule.” Under the discovery rule, the accrual of a cause of action is delayed, in appropriate circumstances, until the injured party actually discovers, or by the exercise of reasonable diligence and intelligence reasonably should have discovered, that he may have a basis for an actionable claim.
See Staub v. Eastman Kodak Company,
Knowledge or discovery of the basis for an actionable claim will be imputed where the Plaintiff was aware or, by exercise of reasonable diligence, should have been aware: (1) that he has been injured; and (2) that the injury is due to the fault or neglect of an identifiable individual or entity.
See Lynch,
Discovering that one might have a basis for an actionable claim “means perceiving an injury and believing, or having reason to
believe
— with
a degree of firmness that would lead a reasonable person to investigate the matter if he is interested in seeking redress
— that his injury was probably caused by the fault of another. Certainty is not required.”
Eastman Kodak.,
Several New Jersey Supreme Court decisions have addressed the state of knowledge required to impute discovery of a possible causal relationship between plaintiffs injuries and a particular product and to, trigger the running of the statute of limitations.
See Burd,
In
Burd,
a contractor’s laborer, who had sustained a heart attack while working in a trench gluing together plastic pipe, brought a products liability action against the supplier and the manufacturer of the industrial glue, claiming that the glue contained a noxious substance which, given the confined environment in which he was working, was a substantial contributing factor in bringing about his heart attack.
The regular incidence of lightheadedness and dizziness while using the glue, and the disappearance of the symptoms shortly after cessation of plaintiffs exposure thereto, together with the permissible inference from proofs that plaintiff realized the connection between the glue and the symptoms (although at trial he denied such knowledge), furnishes a substantial credible basis for an inference of knowledge by plaintiff at least shortly after the heart attack that the exposure to the fumes of the glue in the warm trench was in some way related to the attack.

Vispisiano,
a former employee at a toxic-waste disposal site brought suit against the suppliers, processors, manufacturers, and distributors of the toxic-waste materials to recover damages for medical complications and physical ailments allegedly resulting from his exposure to toxic chemical wastes during the six months he was employed at the site.
*482
The New Jersey Supreme Court ultimately reversed a grant of summary judgment on statute of limitations grounds after finding the information available to the plaintiff insufficient to put him on notice that his exposure to toxic chemicals might have caused the injuries that were the subject of his suit. The Court expressly noted that specific “medical confirmation” of causation is not necessary to trigger the statute of limitations, reaffirming a principle implicit in its decision in
Burd. Id.

In
Gmves,
the New Jersey Supreme Court, while not explicitly relying on the standard set forth in
Vispisiano,
essentially extended that case’s holding to a products liability action alleging liability for failure to warn of the dangers of ingesting a commonly used household product.
While plaintiff had included his ingestion of baking soda as part of his medical history, no medical report filed with the hospital following the incident either “asserted or suggested that plaintiffs acute reaction was caused by any aspect of the baking soda.”
Id.
Hospital staff familiar with plaintiffs case were admittedly at a loss to explain what had caused Mr. Grave’s stomach to suddenly and unexpectedly rupture. The cause was discussed at a regular staff meeting on the Friday following the operation, but “no member of the staff, which
*483
included gastroenterologists, questioned the role of the baking soda.”
Id.
Plaintiff continued to experience complications which required a series of six corrective operations and frequent hospitalization. While the records of these procedures “often refer[red] to the stomach rupture as ‘secondary’ to the taking of bicarbonate of soda, no physician associated with [plaintiffs] later care ever believed that the condition was caused by the baking soda.”
Id.
at 259-260,
Four year’s after the incident, one of the plaintiffs co-workers saw a televised news account of a spontaneous stomach rupture.
Id.
at 260,
The Law Division granted Defendant Arm & Hammer’s motion to dismiss on the basis of the statute of limitations. The trial court’s reasoning emphasized the plaintiffs knowledge of his injury, his awareness that his ingestion of baking soda had immediately preceded the rupture of his stomach, and the availability of medical and scientific literature suggesting that the possibility of a causal relationship between baking soda and stomach perforation.
Id.
at 260-261,
[A] layman should not be charged with knowledge of cause and effect, even cause and effect which he may suspect, when the physicians who are treating him and who have the same factual information on which his own suspicions are based completely discount the validity of those suspicions.
*484
Id.
at 261,
Of course, it is easy now to equate the two (baking soda and defective product), but was it easy then? To suggest that the plaintiff should have known that baking soda could cause stomach rupture would attribute to him knowledge superior to that of all the physicians who treated him ... none of whom had ever suggested that his ruptured stomach was attributable to an adverse reaction to the baking soda.
Id.
at 262,
The three dissenting Justices criticized the concurring opinion as marking a dramatic departure from settled law and an unwarranted extension of
Vispisiano. Id.
at 275,
Henceforth, the cause of action in a personal injury case would be deemed to arise not when plaintiff is aware of the facts that may equate in law with a cause of action, but rather when plaintiff and his or her physicians are prepared to prove the medical connection. And so while ignorance of the law remains no excuse, the professional’s medical “unawareness” (no need to resort to the pejorative “ignorance”) would act to excuse a plaintiffs failure to file a complaint in time. Before disallowing application of the discovery rule, a court would have to conclude not simply that plaintiff was aware of facts bespeaking the causative fault of the offending instrumentality, but that his physicians as well were prepared to prove that plaintiffs theory was correct, that the plaintiffs understanding was in fact correct.

The New Jersey Supreme Court recently revisited its decision in
Vispisiano
in a 5-2 opinion which further highlights the difficulty of applying the “standard” articulated in
Vispisiano
to a specific set of facts.
See Lapka v. Porter Hayden Company,
Plaintiff was first diagnosed with pulmonary emphysema over eight years before filing his complaint. Approximately one week after this initial diagnosis, plaintiff was admitted to the hospital after complaining of shortness of breath. A chest X-ray revealed that plaintiff suffered from “pleural thickening” and “increased markings within the lungs” compatible with a “previous inflammatory disease.”
Id.
at 549,
Approximately one and a half years later, plaintiff signed a workers’ compensation claim petition alleging, among other things, “sustained pulmonary and internal organ disability” due to occupational exposure to “asbestos, noise, and chemicals.”
Id.
at 551,
In November 1996, approximately eight years after filing his complaint and just one day prior to his death, plaintiff was once again admitted to the hospital. Id. *486 The admitting attendant completed plaintiffs medical history form, using information elicited during his conversation with plaintiff and plaintiffs wife. The form noted that plaintiff “stoped [sic] working in 1984 when he was diagnosed [with] asbestosis.” Id. Plaintiffs patient chart noted that “according to patient and his wife, this pt has h/o [history of] emphysema & asbestosis & silicosis since '84.” Id Another entry indicated that plaintiff “had h/o COPD [chronic obstructive pulmonary disease] for > 20 yr., c [with] asbestosis silicosis diagnosed about 12 years ago [1984].” Id.
After reviewing the undisputed facts contained in the record, the Court affirmed the lower court’s grant of summary judgment, agreeing that the Plaintiffs claims were barred by New Jersey’s two-year statute of limitations. The Court concluded that plaintiff knew enough by 1984 to prompt diligent inquiry as to whether the exposure to workplace substances was having a deleterious effect on his health.
Id.
at 554,
The Court distinguished its decision in Vispisiano, noting in particular that plaintiffs reliance on his treating physicians’ shared opinion that chemical exposure was not a likely cause of his injuries:
Although the record in Vispisiano contained information allowing the plaintiff to draw a causal connection between his symptoms and occupational exposure to toxins, his doctors discouraged the belief that there was a connection sufficient to form the basis of a cause of action. The plaintiff persisted in learning the cause of his symptoms and eventually obtained the proper diagnosis. On those facts, we held that plaintiffs suit was not untimely in accordance with the discovery rule. We did not hold in Vispisiano that medical confirmation of plaintiffs injury in a toxic tort case is necessary for a cause of action to accrue. Indeed, we carefully noted the distinction between “some reasonable medical support” and “medical confirmation,” requiring only the former for purposes of imputing discovery.
Id.
at 557,
The decisions in these cases illustrate the difficulty of applying the discovery rule to any particular set of facts.
*487
The absence of clear, consistently applied, standards compounds this difficulty. Nevertheless, we can draw from these cases a few principles which help to guide the Court’s application of the rule. Taken together, these eases suggest that, before a cause of action will be deemed to have accrued, a prospective litigant must be shown to have had an informed suspicion— based on “some reasonable medical support” — that a particular product or toxin may have either caused or contributed to the injuries which are the subject of his suit.
See Vispisiano,
Under New Jersey law, the burden of proof with respect to the application of the discovery rule rests with the party seeking to claim the benefit of that rule.
See Lopez v. Swyer,
While the parties do not appear to have provided all of the relevant portions of the record, the undisputed facts presently before the Court leave little doubt that Plaintiff knew he was suffering from impotency and that, more than two years before filing his Amended Complaint — i.e. before October 10, 1998 — he believed or reasonably should have believed — with a degree of firmness that would have led a reasonable person to investigate the matter if he were interested in seeking redress — that his im *488 potency may be causally related to the allegedly defective bicycle seat which is the subject of his products liability action. At his deposition, Plaintiff testified that he first began to suspect that the numbing sensation he regularly experienced while bicycle riding might be related to his impotency at or around the end of September or beginning of October of 1997, approximately three years prior to the filing of Plaintiffs Second Amended Complaint. Plaintiffs suspicions were aroused when he viewed a videotaped recording of the television news program 20/20 discussing, among other things, the link between impotency and bicycle riding. This program included a segment about the ongoing research of Dr. Irwin Goldstein, a urologist at the Boston Medical Center, into the possible link between bicycle seats and impotency. Thus, unlike the plaintiff in Vispisiano, Plaintiffs suspicion that his bicycle riding may be to blame for his erectile dysfunction was not based simply on his own “uninformed speculation,” but rather was based on the research findings of a specialist in the field of urology.
Plaintiff later communicated his concerns about the possibility of a link between his bicycle riding and his erectile dysfunction to his family physician, Dr. LaGuardia, during a visit one month later on October 21, 1997. Dr. LaGuardia appears to have considered the possibility worthy of further exploration and referred Plaintiff to Dr. John Graham, a local urologist, for further examination. Although Plaintiff does not recount the pertinent details of his conversations with Dr. La-Guardia and Dr. Graham, there is no evidence in the record that these physician’s dismissed or downplayed the possibility of a causal link between Plaintiffs impotence and his bicycle riding or otherwise misled Plaintiff. Indeed, a document introduced during Dr. LaGuardia’s deposition entitled “Worker’s Compensation” and dated October 21, 1997, contains the following observation:
He [Yarchak] does suffer with possible impotence related to his bicycling as a police officer. He is having problems over the last year or so, on and off. Seems to be getting worse. I have referred him to Dr. John Graham from urology. This could be secondary to pressure from the bicycle seat causing problems.
(Selle Italia’s Br. in Supp. of Mot. for Sum Judg. at Ex. D.). Dr. LaGuardia confirmed during his deposition testimony that he had dictated these notes following Plaintiffs visit. (Vetta USA’s Br. in Supp. of Mot. for Sum. Judg. at Ex. G). Dr. LaGuardia further testified that his observation that pressure from the bicycle seat might be the cause of Plaintiffs episodes of erectile dysfunction was not simply a recitation of the concerns Plaintiff had communicated to him, but rather was a conclusion that he had reached “independently” based on his own medical expertise and the information provided to him by the Plaintiff. (Id.) Thus, the undisputed evidence reveals that, as early as September 1997, Plaintiffs suspicions amounted to more than sort of uninformed speculation exhibited by the plaintiff in Vispisiano. To the contrary, Plaintiffs concerns received “reasonable medical support” from at least one leading researcher in the area and were seriously entertained by his treating physician. Accordingly, the Court concludes that Plaintiff knew or reasonably should have been aware of a possible causal connection between the allegedly offending product and his medical condition more than two years prior to the filing of his Amended Complaint against Defendants Selle Italia and Vetta USA.
Generally, once a prospective litigant knows he has been injured and knows or has reason to know that
someone
*489
has probably been at fault, the statute of limitations will begin to run as to all those individuals or entities within the universe of potential defendants whose identities are reasonably ascertainable, regardless of whether the aggrieved party knows the specific identity of those responsible for her injuries.
10
See Apgar v. Lederle Laboratories,
In any action, irrespective of the amount in controversy, other than an action governed by R.4:4-5 (affecting specific property or res), if the defendant’s true name is unknown to the plaintiff, process may issue against the defendant under a fictitious name, stating it to be fictitious and adding an appropriate description sufficient to identify him. Plaintiff shall on motion, prior to judgment, amend his complaint to state defendant’s true name, such motion to be accompanied by his affidavit stating the manner in which he obtained that information.
Rule 4:26-4 has been construed to “permit a plaintiff who institutes a timely action against a fictitious defendant to amend the complaint after the expiration of the statute of limitations to identify the true defendant. Where this procedure is followed, the New Jersey courts have recognized that an amended complaint specifically identifying the defendant by its true name relates back to the time of filing of the original complaint, thereby permitting the plaintiff to maintain an action that, but for the fictitious party practice, would be time-barred.”
Viviano,
The statute of limitations does not necessarily begin to run as to all potentially responsible parties at the moment a plaintiff knows that some identifiable individual or entity is potentially responsible for his injuries.
See Gallagher v. Burdette-Tomlin Memorial Hospital,
Here again, the standard is not whether a particular defendant’s potential involvement in causing plaintiffs injuries was certain, provable, or even probable, but rather whether plaintiff knew or reasonably should have been aware that such third-parties were potentially at fault for his injuries.
Martinez,
No such equitable considerations exist here. A reasonable person in Plaintiffs position, having discovered a possible causal connection between his injuries and his bicycle seat, should have been aware that other business entities involved in the manufacture, design, assembly, and distribution of the bicycle seat may have been responsible for his injuries. Indeed, the potential liability of those business entities involved in the chain of production was arguably implicit in the nature of the injury itself. Plaintiff points to no evidence that Trek made any representations or assurances which may have misled Plaintiff by, for instance, suggesting that it had been solely responsible for the design, manufacture, assembly, and distribution of the allegedly defective bicycle seat.
That Plaintiff may not have known the specific identities of these business entities is of no consequence. A plaintiffs duty to exercise ordinary or reasonable diligence in pursuing a products liability cause of action includes the responsibility to undertake steps to ascertain the specific
*492
identity of those business entities included in the limited universe of potential defendants responsible for creating and distributing the allegedly defective product. In this situation, Plaintiff was aware or reasonably should have been aware of facts suggesting that he had been injured, that his original bicycle seat was the source of his injury, and that those business entities involved in the production and distribution of this allegedly defective product were potentially responsible for his injuries. However, Plaintiff neglected to invoke the fictitious party rule to preserve claims against those other unidentified entities.
See Knauf v. Elias,
The Court’s conclusion would not impose an unnecessarily rigid or harsh application of the discovery rule or ignore the equitable considerations underlying its application. Upon discovering that the allegedly defective bicycle seat may have caused or contributed to his injuries, Plaintiff still had two years within which to investigate the possibility that other, yet unidentified, business entities involved in the manufacture, design, assembly, distribution, or sale of the allegedly defective product may similarly be responsible or liable for such harm. As it is, Plaintiff did not amend his complaint to include claims against Defendants Selle Italia and Vetta USA until over a year and a half after filing his original complaint against Trek, but offers no offers no explanation for this extended delay. Plaintiff does not maintain, for instance, that he undertook a diligent inquiry to determine whether other business entities had participated in the manufacture and distribution of the product, but was reasonably unable to obtain such information through discovery. Had Plaintiff uncovered information suggesting the potential liability of other unidentified business entities at any time during the discovery process, Plaintiff could have invoked the fictitious party rule to preserve potential claims against these additional defendants while continuing to diligently pursue their true identities. Instead, the procedural history of the case suggests that Plaintiffs Amended Complaint was merely a belated response to Trek’s efforts to pull additional party defendants into the litigation.
The Court therefore concludes, based on the undisputed facts in the record, that Plaintiff either knew or should have been aware of facts suggesting a possible causal connection between the bicycle seat and his impotency and that other business entities involved in the seat’s manufacture and distribution may have caused or substantially contributed to his injuries more than two years prior to the filing of Plaintiffs Second Amended Complaint. Plaintiff is therefore barred, as a matter of law, from asserting his negligence and strict products liability claims against Defendants Selle Italia and Vetta USA. 11 Accordingly, *493 the Court will grant Defendants Selle Ita-lia and Vetta USA’s respective motions for summary judgment on Counts I (negligence) and III (strict products liability) of Plaintiffs Amended Complaint. 12
IV.
In order to sustain his products liability claim, Plaintiff must prove that the alleged offending product is defective and that the defect was the proximate cause of his injuries.
Campos v. Firestone Tire and Rubber Co.,
For purposes of this motion, Defendants Trek and Selle Italia contend that the proffered testimony of Plaintiffs two expert witnesses is inadmissible under Federal Rule of Evidence 702 and that, without such testimony, Plaintiff has failed, as a matter of law, to adduce sufficient proof to demonstrate a causal link between the allegedly offending bicycle seat and his injuries or that there is a danger associated with use of the bicycle seat about which Defendants had a duty to warn. Because the Court concludes that the proffered testimony satisfies Rule 702’s evidentiary standard of reliability and because material issues of fact exist with respect to whether such testimony establishes that the allegedly offending product presented a dangerous propensity which caused Plaintiffs injuries and about which Defendants’ failed to properly warn, the Court will deny Defendants’ motion for summary judgment.
As recently amended, Federal Rule of Evidence 702, which governs the admission of expert testimony in federal court, provides as follows:
If scientific, technical or other specialized knowledge will assist the trier of fact to understand the evidence or to determine a fact in issue, a witness qualified as an expert by knowledge, skill, experience, training, or education, may testify thereto in the form of opinion or otherwise, if (1) the testimony is based upon sufficient facts or data, (2) the testimony is the product of reliable principles and methods, and (3) the witness has applied the principles and methods reliably to the facts of the case.
The admissibility of expert testimony under the standard set forth in Rule 702 is a question of law for the district court. When faced with a proffer of expert scientific testimony, the trial judge must make a preliminary determination, pursuant to Rule 104(a), whether the expert testimony satisfies the standard of “evidentiary reliability” established by the rule and will assist the trier of fact to understand or determine a fact in issue.
Daubert v. Merrell Dow Pharmaceuticals, Inc.,
The first step in the Rule 702 inquiry directs the courts attention to whether the proposed expert witness has sufficient knowledge, skill, training, education, or experience to testify with authority on the particular subject matter or issue on which he or she proposes to opine.
Paoli II,

*495
F.3d at 741. The Third Circuit has “held that a broad range of knowledge, skills, and training” will qualify a witness as an expert and has, therefore, expressly “eschewed imposing overly rigorous requirements of expertise and [has] been satisfied with more general qualifications.”
Id.
As such, the qualifications requirement has generally been liberally construed by courts in this district.
Id.; Holbrook v. Lykes Bros. Steamship Co., Inc.,
The linchpin of the
Daubert/Paoli
analysis is an evaluation of the “relevance and reliability” of the proposed expert testimony.
See Daubert,
Generally speaking, the court’s evaluation of the reliability of an expert’s testimony will focus “solely on the principles and methodology [on which the expert relies], not on the conclusions which they generate.”
Daubert,
*496
Rule 702’s final requirement is that proffered expert testimony must “fit” within the facts of the case. “ ‘Fit’ requires that the proffered testimony must in fact assist the jury, by providing it with relevant information, necessary to a reasoned decision of the case.”
Magistrini,
In exercising its gatekeeping role under Rule 702, this court is mindful of the limited nature of its task and of the need to avoid confusing determinations of admissibility with issues pertaining to the credibility or weight of an expert’s conclusions.
See Kannankeril,
A.
Plaintiff seeks to admit the expert testimony of Dr. Robert Kessler, M.D., a physician and professor of urology at the Stanford University Medical Center, for the purpose of establishing specific medical causation — -that is, to establish, to a reasonable degree of medical certainty a direct causal link between the bicycle seat and Plaintiffs impotence. Employing the technique commonly known as “differential diagnosis,” Dr. Kessler reviewed Plaintiffs family and personal medical history, occupational background, the results of physical examinations, the reports of Plaintiffs treating physicians regarding the treatment of his erectile dysfunction, and postoperative evaluations, and concluded, to reasonable degree of medical certainty, that Plaintiffs impotency was caused by the persistent pressure exerted by his bicycle seat. Specifically, Dr. Kessler opines that prolonged periods of persistent pressure from the bicycle seat caused enduring *497 damage to Plaintiffs perineal arteries, restricting the flow of oxygen-carrying blood to Plaintiffs genitals, and preventing Plaintiff from achieving and maintaining an erection.
Defendants argue that Dr. Kessler’s testimony should be excluded on the grounds that: (1) his “differential diagnosis” fails to adequately rule out alternative possible causes for Plaintiffs impotency; and (2) his conclusion with respect to the specific medical cause of Plaintiffs impotency is unsupported by published, peer-reviewed studies suggesting a causal link between conventional bicycle seats and erectile dysfunction. The Court concludes, however, that the methodology employed by Dr. Kessler in diagnosing the cause of Plaintiffs impotency is sufficiently reliable, and that the absence of any reference to specific, published studies confirming a general causal link between bicycle riding and impotency is, under the circumstances, an insufficient basis for excluding expert testimony which is otherwise based on a reliable methodology. Accordingly, the Court will deny Defendants motion to exclude Kessler’s expert testimony.
Differential diagnosis, or differential etiology, is a methodology or technique commonly used by urologists and other medical professionals in diagnosing an illness or medical condition and determining its cause. A reliable differential diagnosis is typically “performed after ‘physical examinations, the taking of medical histories, and the review of clinical tests,’ and generally is accomplished by determining the possible causes for the patient’s symptoms and then eliminating each of these potential causes until reaching the one that cannot be ruled out, or determining which of those that cannot be excluded is the most likely.”
Magistrini v. One Hour Martinizing Dry Cleaning,
When offered for the purpose of proving specific medical causation, a meaningful or reliable differential diagnosis must specifically ’negate other alternative possible causes.
See Turbe v. Robert A. Lynch Trucking, Inc.,
However, “a medical expert’s causation conclusion should not be excluded merely because he or she failed to rule out every possible alternative cause of a plaintiffs illness.”
Heller,
The Court concludes that Dr. Kessler’s differential diagnosis is sufficiently reliable to satisfy Rule 702’s standard of admissibility. Based on a review of Plaintiffs medical records, Dr. Kessler was able to specifically rule out a number of alternative possible causes for Plaintiffs impotency. (See Certification of Dr. Robert Kessler, M.D., attached as Ex. N to Pl.’s Opp. Br.). For instance, he observed that Plaintiff did not suffer from diabetes, neurological disease, or high blood pressure, medical conditions commonly associated with impotency in young males. (Kessler Dep. at ¶ 51-52). Dr. Kessler also offers reasoned explanations for dismissing or discounting additional factors suggested by Defendants. For instance, he notes that any possibility that Plaintiffs erectile difficulties could be explained by psychological factors alone is belied by the results of the arteriogram which revealed actual physical damage to Plaintiffs perineal arteries and the apparent success which vascular surgery had in resolving Plaintiffs erectile dysfunction. (See Cert. of Dr. Kessler, Pl.’s Opp. Br., Ex. N; Kessler Dep. at ¶ 89-90). Cigarette smoking and obesity, he observes, while perhaps increasing the incident of impotency among persons suffering from other serious health problems, cannot explain Plaintiffs persistent impotency in light of Plaintiffs age, body weight, and the relative infrequency with which he smokes tabacco. (Kessler Dep. at ¶ 53-54; 82-83). Dr. Kessler concedes that he cannot conclusively rule out the possibility that the damage to Plaintiffs arteries was the result of a combination of acute and chronic injuries; however, he notes that the pattern of damage displayed by the angiogram is more indicative of chronic pressure than of a single incident of blunt force trauma. (Kessler Dep. at ¶ 68-69). Dr. Kessler’s testimony is further supported by the relatively strong temporal relationship between Plaintiffs *499 use of the bicycle seat and the onset of his physical symptoms of impoteney. This is the type of temporal relationship that might reliably support a conclusion that frequent and persistent pressure from the bicycle seat was the cause of Plaintiffs impoteney.
Defendants further contend that Dr. Kessler’s testimony should be excluded because the medical studies and articles which he references do not establish a general causal link between bicycle riding and impotence. However, as the Third Circuit has recently observed, neither
Daubert
nor
Paoli
necessarily require that a physician “always cite published studies on general causation in order to reliably conclude that a particular object caused a particular illness.”
Heller,
B.
-Plaintiff seeks to introduce the testimony of Dr. Steven Batterman, PhD., a consultant on forensic engineering, accident reconstruction, and biomechanics, for the purpose of establishing general causation—that is on the issue of whether, by virtue of its design, the bicycle seat utilized by Plaintiff while a member of the Willamantic police department’s bike patrol unit presented a dangerous condition capable of causing erectile difficulties in male riders. According to his curriculum vitae, Dr. Batterman served for 33 years as a member of the University of Pennsylvania’s faculty as a professor of bioengineering and applied mechanics, teaching courses and supervising dissertations on topics including mechanical and structural design, biomechanics, and safety engineering. For approximately 25 of those years, Dr. Batterman held a joint appointment as a professor in the Department of Ortho-paedic Surgery at the University’s School of Medicine where he supervised various research projects in the area of biome-chanics and taught a course to orthopaedic residents about the biomechanics of the musculoskeletal system.
*500 The principal focus of Dr. Batterman’s preliminary report is on the “elements of the biomechanics of bicycle riding in relation to the manner in which people sit on standard or conventional bicycle seats,” like the Trek seat which is the subject of this litigation. (Selle Italia’s Br. in Supp. of Mot. for Sum. Judg. at Ex. F). Dr. Batterman opines that, regardless of the specific design of a particular bicycle’s frame, the design of a conventional bicycle seat concentrates pressure on the perineum, thereby compressing the perineal arteries and obstructing the flow of blood to the penis. (Id.). Persistent and frequent pressure from such seats may, over time, result in the more permanent compression of these arteries, causing some male riders to experience difficulty obtaining and maintaining an erection. (Id.) Dr. Batter-man’s conclusions are based, inter alia, on an inspection of the bicycle seat itself and a review of various documents, including a laser copy of a photograph of the subject bicycle, owner’s manuals and brochures for Mongoose bicycles like that used by the Plaintiff, Plaintiffs medical records, and Dr. Kessler’s preliminary report. (Id.).
Defendants contend is that Dr. Batter-man’s proposed expert testimony on the issue of general causation fails to satisfy Rule 702’s threshold standard of admissibility because: (1) Dr. Batterman is not qualified to offer testimony regarding “human anatomy and the medical affect that bicycle riding has on specific portions of the body”; (2) Dr. Batterman’s opinion is based on an invalid and unreliable methodology; and (3) the articles referenced in Dr. Batterman’s preliminary report do not support his conclusions with respect to the general causal link between conventional bicycle seats and erectile dysfunction. The Court rejects each of these asserted basis for excluding Dr. Batterman’s testimony and will, therefore, deny Defendants’ motion.
In
Kumho Tire Co. v. Carmichael,
Acknowledging the need for “flexibility” in applying the Daubert’s gatekeeping requirement to technical or nonscientific testimony, the Supreme Court in
Kumho
emphasized “that the law grants the district court the same broad latitude when it decides
how
to determine reliability as it enjoys in respect to its ultimate reliability determination.”
Id.
at 142,
This Court need not devote much time to Defendants’ first argument. In light of the liberality with which the Third Circuit has applied the qualifications prong of the
Daubert/Paoli
analysis, the Court is satisfied that Dr. Batterman’s 25 years as a professor of biomechanics at the University of Pennsylvania’s medical school more than qualify him to offer his opinion with respect to the affect of the bicycle seat on specific portions of the male anatomy. An expert need not have a medical degree in order to reliably testify about relatively uncomplicated aspects of human anatomy.
See Diaz,
Defendants’ primary contention is that Dr. Batterman’s testimony should be excluded because he fails to employ a reliable methodology and does not support his conclusions with specific references to peer reviewed articles or studies establishing a link between bicycle seats and erectile dysfunction. The Court rejects both these arguments, however. As the Court acknowledged in
Kumho,
in some circumstances, an expert opinion based exclusively on a “visual or tactile inspection” or “skill or experienced-based observation” may, depending on “the nature of the issue [in dispute], the expert’s particular expertise, and the subject of his testimony,” satisfy Rule 702’s threshold of evidentiary reliability.
Id.
at 150,
Accordingly, the Court concludes, for purposes of this motion, that the testimony of Plaintiffs two expert witnesses is admissible under Rule 702. In light of this testimony, material issues of fact exist with respect to whether such testimony establishes that the allegedly offending product presented a dangerous propensity which caused Plaintiffs injuries and about which Defendants failed to properly warn which preclude entry of summary judgment in favor of Defendants. Defendants motion for summary judgment will, therefore, be denied.
V.
Defendant Trek also seeks summary judgment on its third party claim for common law indemnification against co-defendant Selle Italia, which is contained in Count II of Trek’s Third Party Complaint. At the outset, the Court notes that there is a dispute between the parties with respect to whether New Jersey or Connecticut law governs the resolution of this specific issue. However, because the Court concludes that summary judgment must be denied regardless of which state’s law supplies the rule of decision on this issue, the Court need not reach this issue in order to reach a proper disposition of Trek’s motion.
See Williams v. Stone,
VI.
For the forgoing reasons, the Court will grant summary judgment with respect to Plaintiffs negligence and strict products liability claims against Defendants Vetta USA and Selle Italia on the grounds that such claims are barred by New Jersey’s two-year statute of limitations. However, the Court will deny Defendant Trek’s motion for summary judgment against Plaintiffs strict products liability claim. The Court will also deny Defendant Trek’s motion for summary judgment with respect to its third party claim for common law indemnification against co-defendant Selle Italia. The Court will enter an appropriate order.
ORDER GRANTING DEFENDANTS VETTA U.S.A., LTD. AND SELLE ITALIA, S.R.L.’S MOTIONS FOR SUMMARY JUDGMENT ON COUNTS I AND III OF PLAINTIFF’S AMENDED COMPLAINT AND DENYING DEFENDANT TREK BICYCLE CORPORATION’S MOTION FOR SUMMARY JUDGMENT ON COUNT I OF PLAINTIFF’S AMENDED COMPLAINT AND COUNT II OF ITS THIRD PARTY COMPLAINT
This matter having appeared before the Court upon Defendants Trek Bicycle Corporation, Vetta U.S.A., Ltd., Selle Italia, S.R.L.’s Motions for Summary Judgment, and the Court having considered the submissions of the parties, for the reasons set forth in an opinion issued by this Court, which findings of fact and conclusions of law are incorporated herein by reference, and for good cause appearing,
IT IS on this 25th day of June, 2002,
ORDERED THAT:
1. Defendant Vetta U.S.A., Ltd.’s Motion for Summary Judgment with respect to Count I (negligence) and Count III (strict products liability) of Plaintiffs Amended Complaint is hereby GRANTED;
2. Defendant Selle Italia, S.R.L.’s Motion for Summary Judgment with respect to Count I (negligence) and Count III (strict products liability) of Plaintiffs Amended Complaint is hereby GRANTED;
3. Defendant Trek Bicycle Corporation’s Motion for Summary Judgment with respect to Plaintiffs strict products liability claim, contained in Count III of Plaintiffs Amended Complaint, is hereby DENIED.
4. Defendant Trek Bicycle Corporation’s Motion for Summary Judgement with respect to its third party claim for common law indemnification against Co-defendant Selle Italia, S.R.L., contained in Count II of Defendant Trek’s Third Party Complaint, is hereby DENIED.
5. Plaintiff may proceed with his claims for negligence (Count I), breach of express and implied warranty (Count II), and strict products liability (Count III), against Defendant Trek Bicycle Corporation. Plaintiffs claim for breach of implied or express warranty against Defendants Selle Italia, S.R.L., and Vetta USA, Ltd., also remains in the litigation.
6. Defendant Trek Bicycle Corporation may proceed with its third party claims for contribution and indemnification against Co-defendants Selle Italia, S.R.L., contained in Counts I through III of Trek Bicycle Corporation’s Third Party Complaint, and Vetta USA, contained in Counts IV through VI of Trek Bicycle Corporation’s Third Party Complaint. Defendant Selle Italia, S.R.L., may proceed *504 with its cross-claims for contribution and indemnification against Co-defendants Trek Bicycle Corporation and Vetta USA. Defendant Vetta USA may proceed with its cross-claims for contribution and indemnification against Co-defendants Trek Bicycle Corporation and Selle Italia, S.R.L.
Notes
.As far as can be determined by the Court from the abbreviated record provided by the parties, the allegedly defective bicycle seat which is the subject of this litigation was originally manufactured by Defendant Selle Italia, an Italian company, between 1989 and 1993 and was ultimately packaged in a master carton labeled ‘'Trek” and shipped directly to Defendant Trek Bicycle Corporation. (Vet-ta USA’s Br. in Supp. of Mot. for Sum. Judg., Ex. D; Trek's Br. in Supp. of Mot. for Sum. Judg. at Ex. B, p. 41-43). The seat was then eventually distributed to a retailer in Willi-mantic, Connecticut, where it was purchased by Plaintiff along with a Mongoose bicycle. According to the deposition testimony of Steven Merlini, a Sales Manager with Selle Ita-lia, the seat was manufactured with the "Trek" insignia pursuant to purchase orders provided by Orleander, a now defunct Swiss company which is not a party to this litigation. (Trek's Br. in Supp. of Mot. for Sum. Judg. at Ex. B.). At the time, Orleander was the owner of the "Vetta USA” brand name. (Id. at Ex. B., p. 23). Plaintiff alleges that Defendant Vetta USA, a California-based company which incorporated in 1997 and at present appears to license the "Vetta" trademark, is liable as a successor-in-interest for the injuries caused by the allegedly defective bicycle seat. (Vetta USA's Br. in Supp. of Mot. for Sum. Judg. at 3; Trek’s Opp. Br. at 22-23).
. Defendant Brunswick Corporation was dismissed from the above-entitled action by consent of all of the parties on January 30, 2002.
. Neither Selle Italia nor Vetta USA has specifically moved for summary judgment on Count II of Plaintiff's Amended Complaint which asserts a cause of action for breach of express and implied warranty.
. Defendant Selle Italia has asserted cross-claims for indemnification and contribution against co-defendants Trek and Vetta USA. Defendant Vetta USA is similarly pursuing cross-claims for indemnification and contribution against co-defendants Trek and Selle Italia.
. The "Trek” logo was visibly displayed on Officer Yarchak's original seat, along with a marking indicating that the seat had been "Made in Italy.”
. In his original complaint, Plaintiff Yarchak did not name additional fictitious defendants as permitted by R. 4:26-4 of the New Jersey Court Rules.
. This case raises certain issues with respect to whether the substantive law of Connecticut or New Jersey governs Plaintiff's claims. Federal Courts sitting in diversity generally apply the conflicts of laws principles of the forum in which they sit.
See Calhoun v. Yamaha Motor Corp.,
. Plaintiff testified at his deposition that he began to experience periodic episodes of impotency at some point prior to his April 22, 1997, visit with Dr. LaGuardia, his family physician. (See Pl.'s Opp. Br., Exhibit A, p. 73-77). Thus, if we assume, as Plaintiff claims, that the bicycle seat was the cause of his impotency, it appears that he sustained his alleged injuries almost three and one-half years prior to the filing of his Amended Complaint against Defendants Selle Italia and Vet-ta USA.
. Indeed, “one Georgetown University physician who took Graves' medical history testified that he wrote an exclamation point after the reference to sodium bicarbonate to indicate his disbelief.”
Id.
at 259,
. Plaintiff argues that the New Jersey Products Liability Law, codified at N.J.S.A. § 2A:58C-1 et. seq., operates to toll the statute of limitations against Defendants Selle Italia and Vetta USA. Subsection (a) provides that:
In any product liability action against a product seller, the product seller may file an affidavit certifying the correct identity of the manufacturer of the product which allegedly caused the injury, death, or damage.
Subsection (e) of the same provision further provides that:
The commencement of a product liability suit based in whole or in part on a doctrine of strict liability against a product seller shall toll the applicable statute of limitations with respect to manufacturers who have been identified pursuant to the provisions of subsection a. of this section.
However, the record contains no indication that Trek Bicycle Corporation, the product seller and distributer, ever filed an affidavit pursuant to 2A:58C-9(a) certifying either Selle Italia or Vetta USA as the manufacturers of the specific product or component which allegedly caused Plaintiff's injuries. The tolling provision of the New Jersey Products Liability Law therefore does not appear to be applicable.
. The Court observes that, based on the forgoing analysis, Plaintiffs negligence and strict liability claims against Defendants Selle Italia and Vetta USA would similarly be barred under Connecticut’s statutes of limitations for such claims. Connecticut's relevant statute of limitations provides in relevant part that "no product liability claim ... shall be brought but within three years from the date when the ... injury is first sustained or in the exercise of reasonable care should have been discovered ...” C.G.S.A. § 52-577a(a). Although Connecticut's Supreme Court has not had occasion to construe the "discovery” language of Section 52-557a(a), the language used is identical to the discovery language of the state's two-year statute of limitations for claims sounding in negligence,
see
C.G.S.A. § 52-584, which the Court has had occasion to interpret. The Connecticut Supreme
*493
Court, in interpreting that statute, has noted that the statute of limitations will begin to run when a party discovers or in the exercise of reasonable should have discovered that he has suffered "some form of
actionable harm." Burns v. Hartford Hospital,
. Defendant Vetta USA also moves for summary judgment with respect to Count I (negligence) and Count III (strict products liability) of Plaintiff's Amended Complaint on the grounds that no genuine issue of dispute exists with regard to the company's lack of direct involvement in the manufacture, distribution, or sale of the allegedly defective bicycle seat. Because the Court concludes that Plaintiff is statutorily barred from asserting these claims against Vetta USA, the Court need not reach this issue.
. Neither side has suggested that Connecticut and New Jersey law differ with respect to the basic elements and proof required in a failure-to-warn products liability action in a manner which will affect the Court’s disposition of the instant motion. Therefore, for purposes of this motion, the Court will postpone its determination of which substantive law governs Plaintiff's cause of action until the parties have had an opportunity to fully brief the issue.
. The Court agrees with Defendants that insofar as Dr. Batterman proposes to testify regarding the specific medical causation of Plaintiff's impotence, he lacks sufficient qualifications to testify with authority on this subject and has not employed a methodology on which he could reliably base such conclusions.
