So I just got my first roadbike (K2 Mach 2) with Shimano Tiagra components and Shimano 105 rear derailleur. Everything seems decent about the bike especially for the price that I got it ($465 discounted from $800). My only thing is that the rear derailler is not exactly centred over the casette so that when I shift in the rear, the chain will jump and engage etc. but it will make a small ticking noise as the chain comes off of the rear deariller and onto the casette. Should I be bothered to try and adjust the little screw somewhere in there or just leave it be? If so where is that little screw?
Thanks a Bundle,
