Abstract: A bicycle disc brake rotor comprises a friction member and a cooling member. The friction member includes at least one friction surface and a first inner peripheral edge. The cooling member includes a cooling body. The cooling body includes at least one cooling surface and a second inner peripheral edge. The second inner peripheral edge is provided radially inward of the first inner peripheral edge with respect to a rotational center axis of the bicycle disc brake rotor. The radially outer part is provided radially outward of the cooling body. The second inner peripheral edge is offset from the radially outer part in an axial direction parallel to the rotational center axis of the bicycle disc brake rotor.

Abstract: A hydraulic device comprises a base member, a piston, a seal ring, and an intermediate member. The base member includes a cylinder bore and an annular groove. The annular groove includes a first inner surface and a second inner surface. The piston is movable relative to the base member from a rest position toward an actuated position in a second direction opposite to a first direction. The piston is movable relative to the base member from the actuated position toward the rest position in the first direction. The seal ring includes a first axial surface facing in the first direction and a second axial surface facing in the second direction. The seal ring is provided in the annular groove so as to define a clearance between the first axial surface and the first inner surface. The intermediate member is provided in the clearance.

Abstract: A disc brake rotor comprises a hub engagement member, a friction member, a first member, and a second member. The hub engagement member is configured to engage with a hub assembly. The friction member is provided radially outwardly of the hub engagement member with respect to a rotational center axis of the disc brake rotor. The friction member has an axial thickness in an axial direction with respect to the rotational center axis. The first member extends between the hub engagement member and the friction member. The first member includes a recess that has an axial depth in the axial direction. The axial depth is larger than the axial thickness of the friction member. The second member is at least partly provided on the recess without using a screw connection.

Abstract: A brake caliper for a bicycle includes a housing configured to be installed on the bicycle, the bicycle including a disc attached to a wheel of the bicycle. A brake pad is installed within the housing and is configured to move between a braking position and a non-braking position. The braking position is a location within the housing where the brake pad contacts the disc when the housing is installed on the bicycle. The non-braking position is a location within the housing where the brake pad is further from the disc than in the braking position. The caliper also includes a biasing member configured to bias the brake pad in a downstream direction within the housing with the brake pad is in the non-braking position, the downstream direction being parallel to a direction of rotation of the disc when a wheel of the bicycle is rotating to move the bicycle forward.
