Abstract

A bicycle crank assembly is provided with a crank arm that includes a first outer shell, a second outer shell, and a pedal attachment structure. The first outer shell is a one-piece, pressed sheet metal member with the projecting part being a bent portion that defines the first pedal axle opening. The first outer shell has a projecting part projecting from the first outer shell in an axial direction. The first and second outer shells are adhesively attached together to form an interior cavity. The pedal attachment structure includes an abutment face with a recess formed in the abutment face such that the abutment face contacts the first outer shell adjacent the first pedal axle opening and the projecting part of the first outer shell is disposed in the recess of the pedal attachment structure.
