given there’s no search function I thought I’d just check...
going from a 9sp Sora road triple (50-39-30) to 11sp 105 double (52-36)...do I need a new front mech?
heard people say you need a mech to match the chain width and that the 9sp triple will not Work as well with 105 as one designed for the group set...but in reality is there likely to be a major difference?
