I'm getting new carbon wheels, and contemplating between getting a 10 spd hub or a 11 spd. My good bike has 10 speed Force right now. It's possible that I might upgrade in the next couple of years to a better bike, that might come with a 11 spd groupset. I understand that to do this, I would need a spacer, which compromises a little stiffness in the hub. I'll be using these wheels pretty much exclusively for racing. Has anyone done this before? Any advice?
and with the way they're marketing over the years, how long before they reach 12 speed? and at what point will it stop, and we can just all have the same speed cassettes?
