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 and is equal to or larger than 55 mm. The sprocket support body includes a plurality of external spline teeth. The plurality of external spline teeth includes a plurality of external-spline driving surfaces. The plurality of external-spline driving surfaces each includes a radial length defined from a radially outermost edge to a radially innermost edge. A total of the radial lengths of the plurality of external-spline driving surfaces is equal to or larger than 7 mm.
