Abstract

A simple, finitely indexable bicycle crank arm extender that is readily, universally and securably installable on a bicycle crank arm including an elongated member having an inner end, an outer end and a plurality of transverse, threaded throughbores. The inner end of the elongated member mounts on the crank arm with a U-bolt that clamps the elongated member and crank arm together. The outer end of the elongated member mounts on the crank arm with a threaded fastener that is received in the distally-disposed threaded bore of the crank arm and threadingly engages one of the plurality of threaded throughbores in the elongated member. A pedal is rotatably mounted at the outer end of the elongated member.
