Abstract:
A bicycle hub comprising:a hub axle; a hub shell including: a first tubular member having a first hub flange secured thereto; and a separate second tubular member having a second hub flange secured thereto; bearings disposed between the hub shell and the hub axle for rotatably supporting the first tubular member and the second tubular member relative to the hub axle; a generator mechanism housed in the first tubular member and adapted to generate electricity by rotation of the first tubular member relative to the hub axle; a brake force adjusting mechanism housed in the second tubular member and adapted to limit a maximum damping force of a brake, wherein the brake force adjusting mechanism comprises: a brake force receiving member rotatably mounted relative to the hub axle for receiving a braking force from a brake mechanism; and a frictional coupler for forming a frictional link between the second tubular member and the brake force receiving member; wherein the frictional coupler prevents locking of the hub shell relative to the hub axle regardless of the force received by the brake force receiving member.
