We feel that as part of buying the best products you should also get the best service. All of our products are designed to be as user friendly as possible. However, if you're not a bike mechanic and cannot find a friend or local shop you trust, give us a call. We'll take your Chris King product in, inspect it, and service it as necessary to get it back up and running in top form. This service is not free, but about what you'd expect from your local shop.
