I have a Miyata 1000 frame that is currently being built up and I'm going back and forth with the wheel build.
My first option is to get a set with XT hubs and Mavic A719 hoops. Great price and it looks like a strong wheel but I would have to spread the stays from 126 to 135.
Before I do this, I'm wondering if there is a rear freehub spaced at 126mm for a 36 spoke wheel? It would have to take a 7 speed shimano hyperglide cassette. Perhaps early Dura-Ace? I thought I found one at Harris Cyclery but they just went out of stock.
I'm new to the wheel-building world so any knowledge you can give would be greatly appreciated.
Edit: I'm using friction bar end shifters and the stock shimano 600 triple crank. I also really like the looks of the Mavic A719 rims so I want to build a new wheelset.
