Just been trying to fit a front mech to my FTM. Tried a SRAM X9 off my old Trek Fuel carbon, and also an SLX. Both are top pull, high mount, 34.9 (I think).
Neither seems to sit just right, the seat tube either isn't perfectly circular or should I be using a different mech? The SRAM fits slightly better.
Didn't think they did any bigger band size than 34.9?
What are other people using?
