Okay, not getting the two most cross-chained gears can be considered a flaw as much as a feature.
54/30 and 40/11 are gears I am fine without.
Open WI.DE (2019) - 8.7kg
Specialized Shiv TT Disc (2020) - 7.9kg
Specialized SW Æthos (2021) 6.5kg
Trek Émonda SLR9 (2021) 7.3kg
Specialized SW Crux (2022) 7.9kg

*all weights are race ready bikes, large frame size.
Sold: SW Venge, S5 Disc, Roubaix Team

12+10=22 - number of gears you get on new electronic-only dura-ace r9200
11+11=22 - number of gears you get on old mechanical dura-ace r9100
12+12=24 - number of gears you get on mechanical campagnolo
You can tell numbers to say the positive or negative message you want to transmit...

12+10 is the standard 50-34 and 52-36 settings.When you use a 39 small ring,12 + 12 is allowed (24 gears). Than it is possible to put 39 parameter with etube and make the system work with 24 gears (also if you use a 34 or 36 ring).
Ths was all ready the same rule with 9150 and 9170 di2 transmissions,

With r9100 it is the same as r9200: 11+9=20.

Question for the gurus. I just got my new sworks sl7 with DA9250 group set.

The braze on mount supplied fits the previous dura ace FD 9170 perfectly but seems a bad fit for the new 9250 FD.

When tightened down 7nm it kicks out the cage and makes it hard to align correctly.

I've got it set to -19 in the 11-52 trim setting also. I feel like the braze on isn't right perhaps. The support bolt is just touching, it's not forcing the cage tail out at all.

Has anyone seen a ultegra or dura ace 11-34 cassette in stock?

Regarding the cage kick-out. If it's reasonably consistent, just start with the cage angled inward a bit, so it kicks out to the correct angle. With sram axs FDs I take a measurement between the derailleur cage and crankarm so I know when it's set correctly. They do the same thing. It's not something new.

That's my issue is when I tighten the braze on bolt it kicks out beyond parallel. With a correct fitting braze on you do it slightly inward then tighten the support bolt to parallel.

I literally cannot tighten it to spec without it being beyond parallel.

And then there's the issue of having to go to -19 in the trim adjustment for the 11-52.

Somethings wrong with the braze on and if you look at it, it just doesn't seem to fit

Has anyone found the Ultegra di2 12s RD & FD on stock anywhere in EU ?

Did you check if the wire isn’t being pinched between the mount and the frame?

Yeah the wire is no problem. I'm almost certain it's the braze on is for the previous di2 FD. it's exactly the same as my friends sl6 and that braze on fits the derailleur.

If you look closely at the photo there's a big gap behind the FD to the braze on.

So you can position it right, but as you tighten the bolt down it forced the FD on a sub optimal angle.

Does anyone have a top down shot of a DA 9200 bike?

I found a FD (r2-bike) but I have not seen a RD yet.

The need for mechanical shifting for top end groupsets is gone IMHO.
Wrong. Many people will always want the nearly 100% reliability of mechanical shifting. Wasn't it the 2019 Paris Roubaix that Sagan won on 9100 mechanical?
It was just because he opted for bigger shifters for this one race. Now new versions di2 are considerably bigger than 9100, so maybe we’ll see him using di2 in 2022.
