Machined from billet aluminum, the Tandems East crankarm shorteners are lighter than their competitors and very effective. The most obvious application is for children, but they are great for shorter adults or anyone that has hip, joint or knee problems that prevent full range-of-motion with a standard length crank. Threads into crank arms and provides four pedal positions shortened by 24, 41, 59 and 76mm.
