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.

摘要： A bicycle sprocket comprises a sprocket body, a plurality of sprocket teeth, a mounting member, at least one fastening member, and a cover member. The sprocket body has at least one first threaded portion. The mounting member has at least one fastening hole configured to be aligned with the at least one first threaded portion in the assembled state. The at least one fastening member has a fastening shaft portion, a fastening head portion, and a second threaded portion. The second threaded portion is configured to threadedly engage with the at least one first threaded portion of the sprocket body in the assembled state. The cover member is configured to at least cover the fastening shaft portion of the at least one fastening member when viewed from an axial direction with respect to the rotational center axis in the assembled state.

摘要： A bicycle bottom bracket assembly having a rotational central axis includes a support member, a bearing unit and a radially inward force reducing structure. The support member includes a hanger mounting portion and a bearing mounting portion. The bearing mounting portion is configured to be at least partly positioned within a hanger part of a bicycle frame. The bearing unit includes an outer race, an inner race and at least one roller element disposed between the outer and inner races in a radial direction with respect to the rotational central axis. The outer race is fixed to the bearing mounting portion of the support member. The radially inward force reducing structure reduces a radially inward force being transmitted to the bearing unit.

摘要： A bicycle bottom bracket assembly comprises an adapter and a bearing. The adapter has a cylindrical shape and extends along a center axis of the adapter. The adapter comprises a resin material. The bearing comprises rolling elements and an outer race. The outer race is configured to contact the rolling elements and is configured to be provided in the adapter. The outer race is partly embedded in the adapter to be prevented from moving relative to the adapter in both axial directions along the center axis.

摘要： A bicycle bottom bracket assembly comprises a first adapter, a first bearing, a second adapter and a second bearing. The first adapter extends along a first center axis of the first adapter. The first bearing comprises first rolling elements and a first outer race. The first outer race is configured to be fitted in the first adapter. The first outer race is slidable relative to the first adapter in both axial directions along the first center axis in a state where the first outer race is fitted in the first adapter. The second adapter extends along a second center axis of the second adapter. The second bearing comprises second rolling elements and a second outer race. The second outer race is configured to be provided in the second adapter such that the second outer race is a separate member from the first outer race.
