On my Cannondale Prophet 700 SL with FSA Mega Exo crank, this is what happens when I run the front derailleur according to Cannondale's FD setup guide here: the chain slightly rubbing the e-type FD plate while in lowest gear up front, thus wearing out the chain as well as scratching the FD plate (the bigger damage slightly higher up btw. is from a case of chainsuck). Has anyone else ever experienced something like this or knows what could be the problem? Should I switch the spacers on the BB around, although this is not according to Cannondale specs? The LBS is no use, as they know absolutely nothing. Thanks!
