  • I know this is the official campagnolo line, but I'm not sold on it. I put a potenza mech and 11-32 cassette on my old man's pre 2014 chorus group, and it worked just fine. Also the 11s tt shifter didn't change between the model iterations.
    Did the cable pull ratios change? If so why didn't the tt shifter change?

  • If I recall correctly, Potenza uses a different spring tension in the rear derailleur, so although that setup will work in the short term, the imbalance between spring tensions in the derailleur and the shifter will cause drift over the long term and require constant adjustment.
