Abstract
A bicycle hub assembly comprises a hub axle, a hub body, and a sprocket support body. The hub body includes a first spoke-mounting portion, a second spoke-mounting portion, and a first axial length. The first axial length is defined between a first axially outermost part of the first spoke-mounting portion and a second axially outermost part of the second spoke-mounting portion in an axial direction with respect to a rotational center axis. The first axial length is equal to or larger than 55 mm. The sprocket support body is rotatably mounted on the hub axle about the rotational center axis. The sprocket support body includes at least ten external spline teeth configured to engage with a bicycle rear sprocket assembly. Each of the at least ten external spline teeth has an external-spline driving surface and an external-spline non-driving surface.
