Patent ID: 10525768

Abstract:
A bicycle hub assembly comprises a hub axle, a hub body, and a sprocket support structure. The hub axle includes an axle through-bore that has an axle minimum inner diameter equal to or larger than 13 mm. The hub body has a first body end and a second body end opposite to the first body end in an axial direction with respect to a rotational center axis. The sprocket support structure is rotatably mounted on the hub axle about the rotational center axis. The sprocket support structure includes a first torque-transmitting profile and a first externally-threaded portion. The first torque-transmitting profile is configured to transmit a rotational force. The first externally-threaded portion is configured to threadedly engage with a first internally-threaded portion of a first lock member. The first torque-transmitting profile is closer to the first body end than the first externally-threaded portion in the axial direction.
