Campy Experts: 11-32 Potenza Cassette w/ 2015+ Derailleur/Shifters

[maximus]

Sorry if this has been asked already, but a quick search didn't turn it up.

I have a newer style Chorus 11s Group (2015+). Currently running 11-29 Chorus cassette. Could the RD support a 11-32 Potenza cassette and is the indexing/spacing the same as other newer style groups? Campagnolo is obviously saying max of 29t...

Running semi-compact fwiw.

Not sure I want to waste money experimenting and can usually find a definitive answer to such questions around these parts.

Thank you!

11-32 and a 36-52 (21 + 16 = 35 tooth difference) will require the Potenza Mid cage rear derailleur.

some people have got it to work... you would be better off with a mid cage derailleur though

[Black Dog]

You can swap cages if you want to keep the chorus derailure and not use the potenza.

Thanks for the replies. Thought I might be able to push beyond the recommended spec but sounds like a no go with the current derailleur.

Def an area that the S's have the edge...

Just replace the Chorus cage with a Potenza cage, works perfectly. I've been running mine for a couple months now or so and zero problems. Shifting might even be better.

Works for me. No probs, but I'm using a compact crankset.

I'm running pre-2015 Chorus RD with 32 teeth Potenza cassette. Works just fine when you're in the small ring on the front, big ring on the back.

BTW: the interesting move will be to go bigger on the back using a Shimano cassette with Potenza RD :-)

The cogset spacing is the same. Depending on your frame and der hanger, the 'standard' rear der may work fine. That is, no droopy chain in small/small and no pulley dragging on cogset in lowest gears...AND enough chain for big-big combo. The 'numbers' presented by all manufacturers are very conservative. Put it on and try it.

Slightly OT but related: I'll find out later this week if a Shimano CX70 FD (bottom pull) works with Potenza shifters.

Update: It works.
