help with chainline
So i just got a touring bike that came with a road triple square taper crankset (FSA VERO) I'm planning to swap this crank for an FSA Dyna Drive MTB triple and I'm a bit concerned about the chainline. I'm not sure I fully understand why there are so many differences in chainline between different types of cranks but I suspect that in the case of road vs MTB, the 135mm rear hub spacing is part of why it needs to be spaced wider. In this instance, its a MTB crank going on a road frame with a 130mm rear hub so in reality, I should just keep the same bottom bracket and not get one with a longer spindle correct?
