I have a set of speciailized tri-spoke carbon wheels(pretty old, but man they're in great shape!). One that seems obvious that is the rear has threads on it for freewheel and I honestly am lost about how I'm supposed to get this compatible with my bike's setup. I want to use them for racing only. I currently have dura ace 7700 RD. My questions are 1) will this even work and 2) what cassette/adapter/freewheel do I need to buy to get it working? Thanks in advance!
