Hi! I wanted to see who's running the same set up mentioned in the title line? I'm running into problems on mine with that set up. SRAM recommends 2mm spacer on the drive side but when the crank is all the way back, it only gives me like 2-3 mm clearance from the rear triangle. and worse, I noticed rub marks from cranks probably when under load or there's a slight flex. Anyone ran into this problem? Would it be okay to try a wider spacer say 3 or 4mm contradicting SRAM's recommendation?
