Crank Shortener

Description

Adjustable crank length for cyclists with limited knee or hip range of motion. Four different pedal settings available, which can reduce crank length by 24mm, 41 mm, 59 mm or 76 mm.  Standard 9/16″ pedal axle holes.

Crank length can be adjusted as range of motion increases during a recovery process.

Also useful for cyclists with short inseams (under 80cm) who would benefit from turning a smaller radius to resolve or prevent knee pain.

Suitable for use on regular bicycles, ebikes, and indoor exercise bikes like the Peloton bike.

Installs in 10 minutes. Manufactured in USA from high grade aluminum alloy into an attractive shape that easily bolts onto your existing bicycle crank.  Will not scratch or mar crank arms.

Set includes both left and right side adapters and hex wrenches for installation and adjustment.

NOTE: If your pedals are an older style with flats requiring a pedal wrench for removal and installation, you will need a pedal wrench to move your pedals from your existing crank arms onto the crank shorteners.

The use of this product will increase the stance width of the cyclist, equivalent to the width of the crank arm on each side.
