was looking down and back this weekend on a ride an noticed that my 8-speed Campy Record rear jumps a bit to the right (and forward) when I backpedal.
(My wife's similar setup stays steady on the same maneuver.)
I have some suspect that something down there is out of true. Derailleur hanger, chain line, derailleur?
anyone familiar with this glitch and can save me some time in diagnosis?
