With Goldtec hubs can you upgrade the bearings to ceramic or would you have to buy brand new 'Pro' hubs?
You can buy various kinds of ceramic bearing which will fit normal Goldtec hubs, they are very common sizes. I can't think of any circumstances in which that would be a good plan, but yeah, you can do it.
