摘要： A bicycle chain wheel assembly is provided with a chainring mounting structure, at least one chainring, a plurality of fasteners and a plurality of fastener covering structures. The chainring mounting structure has an exterior facing side and an interior facing side with a plurality of chainring mounting openings on the exterior facing side. The chainring overlies one of the exterior and interior facing sides of the chainring mounting structure. The fasteners secure the chainring to the chainring mounting structure via the chainring mounting openings. The fastener covering structures overlie exterior portions of the fasteners to conceal the fasteners from view when viewed from the exterior facing side of the chainring mounting structure.

摘要： 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.
