These Fit Bike Sizing Cranks are the industry gold standard

Purely Custom’s Sizing Cranks have become an industry standard for fit bike sizing cranks. They are durable CNC machined aluminum, easily adjustable and readable with embedded level on each crank arm. These cranks are even rideable when used on a client’s own bicycle. Purely Custom offers these sizing cranks in two sizes: Our Short Version adjusts from 140-170mm, our Standard Version measures 155-185mm. Be sure to select the size of cranks you would like upon ordering.
