Nevertheless, the bike industry must be convinced that it is significantly the lesser of two evils. Things like direct-mounts fm don't just appear out of thin air. Shimano wouldn't have developed them unless the major frame builders/designers had gone to them and said it was what they needed for carbon frames. My guess is they know what they're talking about.highlandsflyer":14e4rpbo said:Using a bolt in arrangement rather than clamp means a change of problem, rather than removal of a problem.
Ring clamping a carbon tube is one thing, exposing a delicate thin carbon wall to localised flex is another.
