Setup is 10spd Chorus FD and a 10spd Record crank (no carbon). To get a decent shift from the small ring (39) to the big ring (53) the adjustment on the FD causes the crank arm to slightly scrape the outer cage of the FD each revolution. I back off one click, nothing rubs and there's about 1mm or less clearance between the crank arm and the outer cage. Any thoughts about getting a good shift without causing the rub? Chain is in good shape, no stretch. It's an IRD 10spd chain, could this make a difference?
