Quick question. I have a new 11 speed group on my bike now. I am coming from a well worn Campy 10 speed group. I notice on the new group that the rear shifting is spot on when there is sufficiant tension on the chain (from power output). Although when soft pedalling the system is kind of slow and noisy. Is this just the way the new 11 speed is or is there an adjustment or cable friction issue? BTW it doesnt matter if im going up or down a cog.
