I thought this would be a trivial fix--just turn in the "L" screw on the front derallieur. No such luck. I have L turned in as far as I can without making the cage rub. When shifting from the middle ring to small with the rear on the largest gear the chain occasionally shifts past the small ring and falls onto the bottom bracket shell. The FD is a Shimano 105 and seems to be set at the correct height (~1mm clearance to big ring) and outer cage is parallel to rings. Ideas?
