The cheap ceramic jockey wheels I’ve used all have the same fatal design flaw. But what is it? Replacing the standard jockey wheels on your rear derailleur with ones that use ceramic bearings, can reduce the friction produced by your bicycle drivetrain, allowing you to put more watts down onto the road, theoretically making you a faster cyclist. Ceramic speed produce incredibly high quality ceramic bearings and bearing components for the bike industry. They are famous for their bottom brackets, pulleys, and jockey wheels, but their products are ludicrously expensive. HOWEVER a much cheaper option is available!
