Abstract

A sprocket support comprises at least ten internal spline teeth configured to engage with a bicycle hub assembly. The at least ten internal spline teeth of the sprocket support includes at least ten internal-spline driving surfaces. The at least ten internal-spline driving surfaces each include a radially outermost edge and a radially innermost edge. A radial length is defined from the radially outermost edge to the radially innermost edge. A total of the radial lengths of the at least ten internal-spline driving surfaces is equal to or larger than 7 mm. At least one internal-spline driving surface of the at least ten internal-spline driving surfaces has a first internal-spline-surface angle defined between the at least one internal-spline driving surface of the at least ten internal-spline driving surfaces and a first radial line. The first internal-spline-surface angle ranges from 0 degree to 10 degrees.
