Product Description

These are the same as fitted to the Club, Hoppley and Trainer unicycles.

Construction: Chromed Steel

  • Axle type: Squared
  • 9/16 threaded
  • You will need a crank puller tool to remove these crank arms. Select the appropriate cotterless crank puller.
  • Sold in pairs

Shorter cranks are preferred by distance riders; The rotation of your legs and knees is significantly reduced, enabling you to relax and ride longer distances. 102-mm crank arms are a standard size on small wheels like 8-inch or 12-inch. 110-mm and 127-mm are typically installed on a 20-inch wheel.

The crank size is the distance from the center of the axle hole to the center of the pedal hole. The smaller the ratio of the crank length to wheel size the faster the unicycle will travel, the larger the more control the unicycle will have.

  1. Solid Replacement Cranks 5 Star Review

    Posted by on Jul 1st 2017

    I purchased to replace cranks on from a Diamondback CS. The pedals came loose and stripped one of them. Perfect fit. Though would suggest if you are doing this order the crank puller that sells as well.

    Overall, they are good. Inexpensive replacements for a cheap product. Would buy again.
