CHRIS KING Rear Hub Freehub O-Ring

Original replacement O-Ring for all Chris King driveshells including R45 Shimano. Not compatible with Campagnolo.

Servicing your Chris King hub regularly will make it perform its best. O-rings don't normally need to be replaced with every cleaning or service, but after a while, it's a great idea to refresh your hub's seals to maximize your hub's ability to keep the grit out. To replace the most exposed seals in your hubs, no special tools are needed.
