View Full Version : Rattle in Rear Hub

The rear hub (new Ritchey Zero System OCR Pro Aero) on my bike makes a loose rattle sound when the wheel is spun slowly. It's as if there's something like a bearing loose in there. When the wheel is moving faster (even at 5mph), there's no sound, presumbly from the centrifugal force. Also with the wheels stopped, I can pick up the bike and shake it and hear it rattle.

This isn't normal, is it? Can I fix it?

Thanks,
James

Freehub ratchets? Try lubing the freehub with a little motor oil.
