I’m putting together an 11 speed Campagnolo build, a decision based on snagging some cheap Potenza shifters on eBay however I’ve now read that the pull ratio for these, Chorus, Record and Super Record is now different to previously and requires a compatible rear-mech. I was hoping to use a nice silver 10speed one as it’s going on a steel frame so has anyone tried mixing these new 11s shifters with older derailleurs? Just wondering if it’s really an issue or just marketing to get you to buy more new things?
In the interest of someone else having the same question, or me forgetting, here's the answer: Annoyingly the new ones need to be matched. My 10 speed Chorus one wouldn't index an 11speed cassette no matter what I tried. I picked up a Potenza one and straight away it was fine. So it's not just marketing, it's built in obscelensce which, after years of Campagnolo having 9,10,11 speed compatibility as long as the levers and cassette match is, to say the least, dissappointing.
Brand new Veloce rear mech now in the classifieds....
