How come you don't offer ceramic bearings?
A. While initially faster, ceramic bearings will wear out because they don't have contact seals. Contact seals are important in bearings because they keep the road grime out of the bearings. Without these seals the bearings will wear out very fast. We build all of our hubs with a high quality steel bearing that creates a low drag wheel with the durability you expect from HED. wheels. The same hubs our pro riders ride are the same hubs you get when you buy our wheels. If they are good enough for the Tour riders they will be perfect for your races or rides
