Campagnolo 12-Speed

[Butcher]

I'll agree with that. I have to adjust the rear mech everytime I swap rear wheels. If Shimano can do this without any adjustments, I suspect their factory tolerences are much tighter. Hard to imagine all the aftermarket wheels will meet those specs.

Has anyone tried the SR 12 EPS rear derailleur with the 11-34 cassette? I know Campy says 11-32 max but I'm pretty sure I can get away with 11-3. I'm going to run it with a Chorus 48/32 crankset so chainlength is not an issue. I wanted lower gearing for my EPS build.

Any experience appreciated!

I got an SR 11 EPS rear derailleur to work with a 12-32 cassette despite the official 29-tooth limit. It required a custom part to make up for the lack of a B-screw. You might be able to do the same.

This happens when you swap rear wheel to a different wheel or it happens everytime you need to take off and put back the same wheel?

I have done this on a Colnago C60 without any problem. I did avoid the large chainring and the largest two cogs.

Swapping wheels. Removing the wheel has no effect on the adjustment [such as fixing a flat tire which I've had too many this year].

Campy Users + Indoor Training Question:

I apologize in advance the brief search I did on this thread didn't give the answers I was looking for. Currently, I'm on an 11s Centaur on my road bike w/ an 11-32 cassette. My indoor trainer has an 11-32 105 Shimano cassette on it because it's cheaper. The 105 cassette functions well enough when I'm on the trainer.

I've recently scored a good deal on a 12s Record gruppo which means I'll need to update my trainer's cassette as well. Since 12s 105 is still not here, I wanted to know if any here has tried other branded 12s cassettes with your campy? even those from aliex?

Chorus cassette? @ trainer

[Butcher]

I posted a thread asking the same question. I got one answer.

My Hammer only allows Shimano. I have an EPS11 and the Shimano cassette works good enough. If/When my EPS12 arrives [paid/ordered in Jan '21], I will be in the same boat. I purchased a Sunshine cassette. I know what you are all thinking.....WTF? Sunshine? It's Aliexpress. Now you understand. Anyway, it should be here in a few days.

I can post pictures of it but since I do not have my EPS12 yet, I will not confirm if it's good or not. As with all Aliexpress ads, the description is a bit vage but I believe the top gears are aluminum. Probably not ideal but for just over $40, I think it was a good choice and I can take on for the team. I purchased a 11-28 but they have a few other options.

I can say, I ordered it on Dec 2 and it's in California now. Should be on my door step in less than a week. Pretty fast so far.

This one has been referenced on a different forum as working very well. The thing is it is meant for Shimano free hub - not sure if that suits.

I ordered a Shimano splined Ztto 12s cassette for my Kickr ($57). It should be here soon so I'll report back how it works on the trainer.

So is it really known to work well with Campy? I'm having difficulties finding the Tacx Campy freehub body anywhere in the EU, so something like this could be an alternative.

Just another data point. I use a Sram XDR cas and hub body on my Tacx Neo. Works perfect with Campag Eps 12. I also use it on my Kickr first Gen in a pinch with 11 sp shimano and it works surprisingly well. I don't head for the top of the cassette though.

Yes - working very well with a Campy drivetrain. This individual has Campy 12 on a bike (I think mechanical Record or SR) and wants to continue using the wheelsets whith Shimano 11s free hub.

As said, I read on a forum, haven't experienced myself.

[Butcher]

I looked into the Sram route but then I would have to purchase a new freehub.
