Hi all, I'm having some issues with the front derailleur on my new bike (Giant Contend SL 1). In the lowest gear (large back, smalll front) no matter what I try, the derailleur won't travel far enough inwards (towards the frame) to stop the chain rubbing against the plastic plate on the derailleur. I've unwound the L limit screw all the way, even tried to angle the back end of the derailleur inwards, but that doesn't stop it rubbing either. Any ideas, or is this just unavoidable some times? Thanks.
