Abstract

See full text

A bicycle crank assembly includes a fixing member for fixing a sprocket to a crank arm. The fixing member includes a radially-extending projection, to prevent the sprocket from moving relative to the crank axle in an axial direction, and an axially-extending base portion, which is secured to the crank arm. A contact part is provided on an inner periphery of the base portion and contacts the crank axle or is provided on the crank axle and contacts the base portion. The contact part permits force to be transmitted between the crank axle and the fixing member to limit flexing of the crank axle assembly.
