Pedalling stiffness is the same with SR 12s and DA 11s, no matter the wavy washers and hirth joints?
You'd need to ask Tadej Pogacar, Caleb Ewan or their friends how they can stand this subpar engineering solution.

Really, get a life. There is zero chance you'd notice lower stiffness of Hirth joint. Outstanding looks and tactile feedback you will recognize for sure though.

DA 9100 is nice, but c'mon. SR 12 is, you know, super - above everything else. And you also get much better laid out rear cassettes than with DA 9100.

I find DA 9100 better than R/SR 11S. Better shifting and better ergonomics.

I am currently building a bike with Record 12s; rim and mechanical - didn't have much more of a choice. I am looking forward to seeing how that compares to DA.

I much prefer Campagnolo especially ergonomics...we are all different and choice is good

9100 is mechanical shifting perfection from a functional standpoint. Once it is setup correctly, it's nearly impossible for a user to cause a mis-shift. Campy (and SRAM to a huge degree) have the ability to mis shift if a user throws the lever a certain way. Or at least that's been my experience. The rest is personal preference.

Campagnolo makes a 12-29 12 speed cassette? Do tell.

With your edit, People will be wondering. I was hoping there was something good coming out of Campagnolo. Under my rock I go.
Your comment made me double check the 12/29 combo which happens to be 11sp not 12. I did try to comment but the thread wasnt cooperating so I just edited instead.
The way it shifted I thought maybe someone at Merlin was mixing and matching 11sp cassettes but after running the 12sp this must be a normal condition. I know Shimano doesnt do this on the same bikes and not that it matters as much as I am more concerned about the combos.

I do like the shape of the Campy levers but I think they could do better with the angle of the button for mechanical shifting too smaller cogs as I think the button should be angled more downwards to make it more ergo. I find I have to lift my hand into a higher position to push the button down from the top of the hoods and when in the drops sprinting its a far reach to hit that button. I wish it was more like their electronic button angle and position. This annoys me so much that I put together a carbon extension and installed it on the button for the rear shifter so I dont have to reach as far from the drops and when on the hoods I dont have to change my hand positions nearly as much. It added 6grams to my overall weights of the bike.
I miss my Sram paddles.

I experimented with handlebars and position of the Ergopower controls to get the thumb button ergonomics right. FSA Compact and Deda RHM bar shapes work for me. Granted, I have large, or rather long hands, long finger gloves size L.
I've used 8, 10, 11 and now 12 speed mech Ergopower controls.

Those mech SRAMs were a nice idea, but rather hopeless in practice. ASX solves it, but they still cannot do the Campag double dump.

Thank you, it looks stunning, especially the crankset :thumbup: The only thing I´d change is the levers finish. The 3K carbon would be better.

I noticed the CULT ceramic bearings were completely dry. I know they are supposed to be, but few drops of Ceramicspeed TT grease can help them to last longer without any performance loss

You will be desapointed to see the Jockey wheels are Rollers... and not Bearings

Cult bearings are almost indestructible. I used gear oil on my set. Very practical, I just washed out dirty oil with new a coouple of times a year.

Has anyone managed to get the 11-34T cassette to work with SR12 EPS? Campy states that the cassette is only meant for 12s mechanical but surely it could be made to work with EPS? The CeramicSpeed OSPW for SR12 EPS can accommodate up to 34T so maybe the stock cage isn't big enough?

The cage length provides wrap capacity. Since it will wrap a 32 and extra wrap must always be included to account for the minimum 1 inch or 4T change that can be made to chain length, wrap capacity is probably not the problem. If you have a 32, shift to the big/big and check for excess chain length. If there's very little, install a 1 inch longer chain, then shift to the little/little and check for chain tension on the lower section. If it's loose or the chain rubs on itself as it passes under the lower pulley, shift to the 12 and see if that works. Most people don't use the little/little.

After all that, the Campy equivalent of the B screw needs to be turned in enough to adequately clear the 34T sprocket, from the little ring. A slightly longer screw might be needed.

This is the procedure that's also needed to use a 10-36 sram axs cassette with their standard 10-33 rated RD. If there's too much clearance set by the B screw, it will result in insufficient wrap on the two smallest sprockets and foul up the 10-11 shift.
