Front derailer replacement
Hi. I'm looking for a replacement of my front derailer, down cable, 48-38-28 crankset. The previous one was not compatible with Shimano indexed shifters. My all other parts are Tourney, however, I couldn't find anything in my local shops that could fit them, at least according to Shimano docs. I was looking for FD-C051, FD-C102, FD-C202. As far as I understand, those are low-end parts. What would happen if I installed something from Alivio, Acera or any other higher series?
