Recently fitted Etap shifters and derailleurs but finding the rear cog is brushing my wheel when in the very lowest gear going up hill.
I can make micro-adjustments and trim all the way across to prevent this but then shifting becomes very jumpy.
I am wondering if making my chain tighter would help pull the drive further away from the wheel?
Im also running a very small rear cassette and wondering if this is a cause of the problem?
(10 speed cassette 11-23)
Anyone experienced in using this new fangled modern witchcraft?
