I'm having trouble shifting to the granny ring on our new (to us) bike with DuraAce FD. When the inner limit is set to Shimano specs it won't shift to granny. Loosen the inner stop and it will shift, but it's prone to dropping the chain. I've experimented with FD height and rotation to no avail.
Will Shimano chainrings make any difference?
Should I just set the inner limit loose and install a jump stop?
2007 CoMotion Supremo, FSA SLK crankset with FSA 30,39,53 rings, DuraAce 7803 FD. I had my LBS adjust it and he set it at a compromise between shifting ok and dropping the chain. This is my first experience with 10 speed and with a CoMotion.
