I have a 26" Nashbar AT-3 that I'm thinking about putting an 2012 SRAM X.9 Drive Train Build Kit on.
It's a Large frame (21"), and I believe I'd want a 175mm Crankset, High B/P and I don't know that I care whether the 9 speed Cassette is 11-32 or 11-34.
That said, I have no idea what the front derailleur measures size is. Do I want 31.8 or 34.9?
Can anyone answer what size I would want for the front derailleur? I'd also love confirmation on the High B/P and any advice on 11-32 vs. 11-34.
