Is there something that you don't like about the rear hub? My understanding is that the FS3 is fairly entry level in its purpose. If the hubs aren't maybe causing an immediate issue, I'd look at upgrading the fork first.....In my experience, in any hobby or sport, upgrading your equipment bit by bit can be fun and "stage" the cost, but it's usually more cost effective to sell the whole bike and upgrade to the platform you'd prefer ...
