View Full Version : Front derailleur problems

I recently bought a Giant Rincon for my brother. The front derailleur is a Shimano CO50 and there are some problems with it. Shifting doesn't go very smooth and is attended with a grinding sound, which often stays after shifting. Since the bike is new and still in the warranty period, I can always bring it to the LBS for a tune-up. The bike needs to be brought in for the first tune-up anyway so that may also play a role.

Anyway, I've read many bike reviews where people complained about the performance of the Altus front derailleur. So considering that the CO50 group is lower then Altus, I was thinking about replacing it if the problems still occur after the tune-up(s). If so, I'm thinking about Alivio or Deore. Any opinions on this?

The grinding sound is most likely the chain rubbing against the side of the derailer cage. You probably just need to get it adjusted.
