The Spirit crank design represents the culmination of extensive rider testing and stress modelling to reduce weight while maintaining high strength. It is the unicycle crank reinvented.

It is a versatile crank design constructed from tough, stiff 7050 alloy for all types of riding, from trials, street and flatland to mountain and long distance. Utilizing the International Spline Interface Standard (ISIS drive), the Spirit crank is available in both single and double hole, featuring External Disc Brake (EDB) compatibility, configurations offering numerous different length options to suit any type of riding.
