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?

Thanks all

How many speeds them there shifters got in 'em? (Count the clicks, add 1).

Sorry, don't know what you are talking about.

Then you need to visit your LocalBikeStore or co-op and take the shifters with you, both right and left. Or you could ask the seller.
