The only issue between 11 and 12s cranksets is that pre-HO 11s are 7.6mm apart and 11HO/12s are 8.0mm. This affects the shifting on 12s mechanical FDs. EPS doesn't care.
I did not test to see if the difference was in the chainrings or the crank arms.

I got a reply from power2max today. They stated that their 4-arm cranksets are compatible with both 11 & 12 speed, which, according to them, is confirmed by Campagnolo. One should use 12-speed chain rings for 12 speed though.

Unfortunately not, as it is the previous 4-arm version (build when there was 11-speed). It no longer shows on their webpage. But as I understood them, all their 4-arm campagnolo cranksets work with both 11 and 12 speed mechanical. I know the cranksets are manufactured specificly for power2max, so who knows about spacing...

Similar question - my used bike came with 11 speed Super Record, 4 arm crankset (175, 50/34). I needed to change the crankset due to arm length hurting my knees and gearing, so I ended up with a 5 arm Super Record crankset in the correct size for me (172.5, 52/36). Finding the correct 4 arm 11 speed crankset has proven elusive. My question is if I can use a 12 speed crankset with everything else being 11 speed? While the current crankset functions great, I really prefer the newer 4 arm appearance.

Yes
The chainline is different as is the chanring spacing. Not so sure it's going to work very well despite people saying so on the interwebs.

Hi everyone,

Does anyone know if it is pssible, or ever tried to install a 12sp rear mechanical derailleur cage on a 11sp rear mechanical derailleur ?

Thanks !

Rémi.

Will the 12s chain play nicely with my 11s Praxis chainrings?
Yes, you'll be fine.

I have an existing 11-speed Power2Max chainset (4-arm) that I would like to use with an upcomong 12 speed build. Is this possible? Can I use the 11-speed chainrings or should I install 12-speed?
As above, 11v rings will be fine.

Yup, good to go.

I'm not totally convinced this is true.

The chainline and distance between chainrings on 12 speed (and for that matter Potenza HO 11 and Centaur 11) is 44.5 and 8mm respectively.

The 2015+ Chorus/Record/Super Record shifters and front mech are designed around 43.5 mm chainline with 7.6 mm spacing.

There's not a lot in it, sure, but whether or not it works may come down to frame size/spec. You'd definitely want to use a barrel adjusted with the front mech to dial it in.

No idea about real world experience, but according to Praxis themselves their current chainrings does not work satisfactorily with Campy 12. They did hope to have new fully compatible chainrings available sometime this coming winter though.
From Praxis wb site 29nov 2021: CAMPY – Praxis rings shift great with the EPS and mechanical Campy 10/11/12sp drivetrains...

I've done it on a number of frames - it works perfectly well.

I hope the Praxis rings are stiffer than the Campy 12 rings cause mine came in at 0.157kg with fasteners. They claim 0.158 52/36 not sure if fasteners included.

Hi, has anyone tried mounting 12s chainrings on 11s cranks?

Has anyone tried Campagnolo 12 speed with Dura-Ace 9100 cranks?
