I bought a set of used wheels recently and the seller was kind enough to give me some combo brake/shifters and brakes. The shifters say Shimano Ultegra Flight Deck on them and the brakes are Shimano SLR Super. The wheels are Ultegra hubs, 130mm. I would like to start getting components for a future build (my first) and since I have these I figure it may be a good place to start.
If I would like to stay with index shifting, what freehub, FD, RD should I be considering?
