BICYCLE CRANK ASSEMBLY

摘要

A crank assembly for a bicycle that includes a spindle mountable to a bicycle frame and first and second bearing assemblies rotatably supporting the spindle. A drive crank arm is made from fiber-resin composite material and is bonded to an end of the spindle. The non-drive crank arm is operatively connected to another end of the spindle. A fastener secures the non-drive crank arm to the spindle. Alternatively, the drive crank arm may be formed monolithically as one-piece with one of the ends of the spindle.
