Campagnolo 11-speed cable pull changed?
I have a bike with Chorus 11-speed components - I think 2011 vintage, though possibly slightly earlier - "Chorus 11 Ultra-shift" is on the box the shifters came in. The rear derailleur is mangled and needs replacing, but I seem to remember reading somewhere that Campagnolo changed the cable pull of their 11-speed components in 2015, though I can't find anything definitive on this. Will a current model Campagnolo derailleur index correctly with my existing shifters? If not, what are the options? Will a post-2001 9-speed Centaur RD index correctly with 11-speed cassette and shifters - a friend has one of those NIB that he will let me have if it will do the job?
