Abstract: A crank arm comprises an arm body, an axle fastener, and a biasing element. The arm body includes a crank-axle receiving opening and an axle-fastener receiving opening. The axle-fastener receiving opening has a second opening axis. The axle-fastener receiving opening is partly in communication with the crank-axle receiving opening by a connection opening. The axle fastener includes a fastener body having a splined portion. The splined portion is configured to engage with the splined end of the crank axle in a mounted state where the crank arm is mounted to the crank axle. The biasing element is configured to bias the axle fastener in a biasing direction parallel to the second opening axis.

Abstract: A bicycle crank axle assembly has first and second crank arms that are attached to opposite ends of a crank axle. The ends of the crank axle are non-rotatably disposed in axle mounting openings of the first and second crank arms. A first end of the crank axle has at least one axially extending first spline that protrudes radially outward from an outer peripheral surface of its middle body portion. The at least one axially extending first spline non-rotatably couples the crank axle to the first crank arm and prevents outward axial movement of the first crank arm away from the second crank arm. The second end portion of the crank axle has at least one recess that extend radially inward with respect to the outer peripheral surface of the middle body portion to form at least one axially extending second spline.

Abstract: A composite bicycle component comprises a first member, a second member, a bonding member, and an inner holding member. The first member is made of metallic material. The second member is made of non-metallic material. The first and second members are configured to form an interior cavity therebetween in a state where the first and second members are attached to each other. The bonding member is configured to attach the first and second members to each other. The inner holding member is configured to be disposed within the interior cavity so as to prevent the first and second members from being separated from each other until completion of attaching the first and second members to each other.

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.

Abstract: 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.
