delivered the Opinion of the Court.
Petitioner, James H. Ghrist, Jr. (Ghrist), appeals the denial of his Crim.P. 35(b) motion for a sentence reduction. He contends that the trial court erred in concluding that it had no jurisdiction to consider his motion because it was based, in part, on post-incarceration conduct. In an unpublished opinion the court of appeals affirmed. Ghrist v. People, No. 92CA1239 (Colo.App. Apr. 14, 1994) (not selected for official publication). We agree with petitioner, and accordingly reverse and remand for further proceedings consistent with this opinion.

In January 1990 Ghrist was convicted of reckless manslaughter in violation of section 18-3-104, 8B C.R.S. (1986). He was sentenced in the aggravated range to twelve years at the Department of Corrections (DOC). The court of appeals affirmed his conviction, and this court denied his petition for writ of certiorari.

On March 6,1992, the court of appeals issued its mandate. On April 20, 1992, Ghrist filed a Crim.P. 35(b) motion for reconsideration of his original sentence. On June 9, 1992, after a hearing, the trial court denied Ghrist’s request for reconsideration finding, “based on its reading of

Colorado Rule of Criminal Procedure 35(b) provides:
Reduction of Sentence. The court may reduce the sentence provided that a motion for reduction of sentence is filed (1) within 120 days after the sentence is imposed, or (2) within 120 days after receipt by the court of a remittitur issued upon the appeal, or (3) within 120 days after entry of any order or judgment of the appellate court denying review or having the effect of upholding a judgment of conviction or sentence. The court may, after considering the motion and supporting documents, if any, deny the motion without a hearing. *812 The court may reduce a sentence on its own initiative within any of the above periods of time.
To decide the question before
us,
we must consider both the purpose of Crim.P. 35(b), and the procedures followed in a hearing on such a motion. Crim.P. 35(b) provides trial courts the opportunity to review a sentence to ensure it is properly imposed before it is final.

[W]e do not by this ruling mean to preclude evidence of a defendant’s conduct during incarceration as a relevant consideration in a Crim.P. 35(b) proceeding, we hold that it is error to modify a defendant’s sentence based only upon such evidence, particularly when the sole rationale is to reward exemplary behavior during incarceration. Id.
We later considered a similar situation in
Mamula v. People,
The court of appeals decided Piotrowski without the benefit of our holding in Mamu-la. Ghrist argues that Piotroivski should not be construed to impose a limit on the evidence a trial court may consider when ruling on a 35(b) motion. Though we agree with Ghrist that the trial court improperly applied Piotroivski to find that it did not have jurisdiction to consider his motion, in our view Fuqua, Piotrowski and Mamula can be reconciled to create a framework for review of Crim.P. 35(b) motions.
First, a reviewing court must determine the timeliness of the motion, considering both when it is filed and when it is heard.
See Fuqua,
A reasonable timeframe for a hearing will depend on whether the defendant seeking review has made a “reasonable effort to secure an expeditious ruling.”
Fuqua,
If the trial court determines that the defendant has met the threshold requirements of timely filing and timely hearing, the court is then free to consider all evidence presented at a 35(b) hearing. This includes evidence of exemplary conduct while incarcerated. Crim.P. 35(b) does not limit the evidence the trial court may consider, and we decline to create such a restriction. In our view the purposes of the sentencing statutes are best served without imposing a judicially created limitation on the evidence consid

ered. We have long held that any decision to reduce a sentence pursuant to Crim.P. 35(b) is entrusted to the sound discretion of the trial court as the “better arbiter of the facts” related to sentencing.
Watkins,
Applying this analysis to the ease at hand, we conclude that Ghrist was improperly denied a full hearing on his Crim.P. 35(b) motion. He filed his motion within the prescribed statutory period after the court of appeals issued its mandate. Indeed, the entire Crim.P. 35(b) proceeding was conducted within the one-hundred twenty day time period. Though we recognize there was a delay between the time the original sentence was imposed and the hearing on the 35(b) motion, this delay resulted from Ghrist’s direct appeal. He should not be penalized for pursuing his right of appeal, or for any delay in deciding that matter.
Ill
The People fail to advance a sound argument that the trial court was without jurisdiction to consider Ghrist’s motion. At oral argument the People contended that a sentence is final once a mandate is received. We find no support for such a novel view. The timely filing of a 35(b) motion suspends finality of sentence while the court reconsiders the original sentence.
See Mamula,

In summary, we hold that the trial court erred in concluding that it was without jurisdiction to consider Ghrist’s Crim.P. 35(b) motion. We therefore reverse and remand this case for further proceedings consistent with this opinion.
