Abstract
The present invention provides a bicycle hub that is usable with a disc brake. The hub has a tubular body extending along a longitudinal axis between the ends thereof. One end of the hub is configured to mate with and retain a brake disc on a disc seat that has a predetermined configuration. Spaced from the disc seat along the longitudinal axis there is a fastener portion of the hub which is configured to receive a fastener that locks the disc on the hub. The disc seat and fastener portion are separated by section of the tubular body that does not form any part of either the disc seat or the fastener portion
