Wondering if anyone can help me with problems with a right hand (rear mech) shifter. These are the Ultrashift type in the Centaur range that Campag stopped making a few years back when they were trying to push 11 speed.
I have dismantled the shifter and put it back together as per the Campagnolo official overhaul video but am unable to solve the problem.
BACKGROUND: There seemed to be one click too many when trying to get on the biggest sprocket and then the cable jammed and the shifters moved freely with no click. A tug on the cable below the boss on the downtube seemed to free it up and the shifter worked again, but did not reliably stay in the biggest sprocket. Other gears seemed to work reasonably well, but shifting was hesitant and unreliable.
ACTION: I have replaced inner and outer cables as well as dismantled and reassembled the shifter, cleaning all parts and regreasing. Parts seem all to be ok, but I'm guessing there is some wear that may be causing the problem. Shifting now seems a bit better, but the fundamental problem of that extra click and jam which led me to strip it all down in the first place remains.
Anyone encountered this particular problem who can help? Cheers.
