I agree about the Stronglight 57, 63, 93, and 105 problems. I have a triple and the chain will jam between ANY TWO of the three rings. Every time I shift, I have to pedal artificially slowly so as not to load the chain, as it skirts between the rings. If I shift under pressure, the chain jams so deeply it's almost impossible to get it out of the crankset. I think the bike is running an SRAM PC-58 chain. I've been reluctant to molest (lightly sand) the crank arm tabs.
It would be good to know who makes the widest modern 3/32 chain??
