Has anyone attempted to use the 11-34 cassette with 12-speed EPS? Campag state that EPS cannot be used with this cassette, but I wonder if it is possible nonetheless. I run 11-34 on my 12-speed super record mechanical group (after changing out the rear derailleur cage plate), but there does not appear to be an equivalent change available for EPS. If it is simply a capacity issue then this could be overcome by never using the big/big combination, but on the other hand if the derailleur cannot move back far enough to wrap around 34 teeth then that would be harder to overcome.

P.S. My apology if this question has already been asked and answered; I didn't have much luck using the search function.

Hello,
I replaced my Chorus 10s group with a Chorus 12s and I see that the Q-Factor is asymmetrical this time. The distance between the left crankarm and the seat tube is 2mm narrower than on the right. Did you see the same thing (BSA 68)? Thank you in advance for your help.
Regards,

Yes, that is certainly the case on my BB386 frame with Chorus 12 cranks. The NDS is 2mm closer.

Thanks for your answer. I wrote to Campagnolo, but got no response. Disappointed...

The asymmetrical comment got me to check my super record 12 speed. My eye (initially) and my calipers (as backup) indicate my super record is completely symmetrical - based off same distance pedal end of left arm vs right arm to the chain stays

USed the Campag chainstay measuring guide and the chain is def too short in the top cogs. Noisy as a mofo.

Also, broke a bloody pin on the way in.

Hello

I want to run the Campagnolo 12 speed mechanical drivetrain on the Scott Addict RC Disc 2020? I know the problem is the front derailleur, since there is no mechanical stop for the housing. Did somebody find a solution for that or does the Shimano Dura Ace FR 9100 work whit that combination?

If I'm understanding your issue the right way, don't you have the possibility of 3D print a mech housing for your frame?

I've replaced a 2015 Record EPS cage for a medium one (from a SR mechanical rear derailleur). At the time because I wanted to use a 11-29 cassette and the Record EPS RD doesn't allow that (if you look into my older posts you'll find my photos of the transformation).

It works flawlessly in that respect and can answer your question. If not, and if the issue becomes the wrap around, you probably will find the solution on a Wolf Tooth Roadlink.

Yes, I have access to a 3D printer, but I do not know how the part should look like or even where to be mounted. Any ideas?

My group ride friends are more than 50% Scott users and most of them have Addicts. I can take a look next time I'm with them but nowadays, with Covid, it will be a difficult task. We don't gather around for about 2 or 3 months now.

Thanks @naavt Good to hear that you were able to find a solution for 11-speed EPS. Hopefully it will be a similar story for the 12-speed version. I would like to try it... but for now it will remain theoretical becuase the parts aren't available!

Not sure if it's ok to advertise like this but for those of you looking for 12-speed EPS, I have a minigroup for rim brakes available:
