I notice my SRAM X Gen front derailleur clamp has some small raised ridges cast into the insdide clamp surface. It is an OEM takeoff purchsed from Jensens. Is this typical? seems like it would damage the frame finish at the least and potentially the tubing itself when clamped down.
Planning to build up a new frame his weekend and am wondering If i should try to grind these down somehow.
