question for the ones more experienced, please
my NX derailleur has the upper pulley with 12 teeth, while the lower one with 14 teeth and I am planning to change these with some color ones.
Asking a bike shop around my area, where I found colored ones, but not with 14t, the bike mechanic there said that it works even if I mount 12T pulley instead of 14T one....does this make sense?
