After observing bike fitters using over-priced sizing stems with sub-par features and too many loose parts, BikeFit researched and developed a better solution. The Stem Sizer delivers a simple, quick and precise way to optimize rider comfort and performance by determining their ideal bicycle cockpit position.

The Details:

  • Single top-mount bolted clamp for easy handlebar changes.
  • Simple push-button feature for the quickest stem length adjustments.
  • Stem length range adjustment from 60 – 145mm in 5mm increments.
  • Accommodates 1-1/4” and 1-1/8” threadless fork steerer tubes.
  • Stem angle adjustment achieved by turning the knob to smoothly move stem angles within +/- 30° range.
  • Beautifully constructed carrying case for the fitter on-the-go.
