Abstract
A hub is configured to suppress deformation in a disc rotor even if the disc rotor is made thinner and more lightweight, and to suppress wobbling in a braking surface. The hub has a hub axle, a hub shell, a pair of bearings, and a brake mount. The hub shell has spoke attachment parts with spoke attachment holes and disposed at both ends for attaching a plurality of spokes. The brake mount has a rotor attachment unit for attaching a disc rotor of a disc brake. The rotor attachment unit is integrally formed with a first spoke attachment part and is disposed radially farther out than the minimum radial position at which the spokes are attached.
Claims19
A bicycle hub comprising:
- a hub axle having a center axis;
- a hub shell rotatably supported on the hub axle by bearings about the center axis, the hub shell including a first end having a first spoke attachment part with a plurality of first spoke attachment points radially spaced from the center axis for attaching a plurality of first spokes thereto and a second end having a second spoke attachment part with a plurality of second spoke attachment points radially spaced from the center axis for attaching a plurality of second spokes;
- and
- a brake mount having a rotor attachment unit integrally formed with the first spoke attachment part, the rotor attachment unit being configured and arranged with a plurality of rotor attachment points to secure a disc rotor of a disc brake device thereto, the rotor attachment points of the brake mount being disposed radially farther out from the center axis than a minimum radial position of the first spoke attachment points at which the first spokes are attached to the first spoke attachment part,
- the rotor attachment unit including a plurality of first arms extending radially from the first end of the hub shell in a circumferential pattern with the rotor attachment points being disposed at outer tips of the first arms, and the first spoke attachment points being disposed on the first arms,
- each of the first arms including a pair of the first spoke attachment points that are substantially radially arranged relative to each other.
