Forgive me for not going back and looking for each post describing the issue, but which cassettes are folks having shifting issues with?

Are they DA? Are they Ultegra? Are they a particular size? Are the issues irrespective of that?
11-30 Ultegra for me with Dura Ace groupset.

Does anyone know if the DA 11-28 cassette will make it to market? I see some places still listing it as an option but Shimano seem to have removed it from their site.

Might it be a regional item, like the rim brake tubular wheels?

That would have been the perfect cassette for me with a 52-36 combo up front.

FWIW, Recon do an 11-28 cassette with the same cogs as the now abandoned DA9200, amongst others:

DA 9200 plays nice with Absolute Black 52/36 oval 11 spd. chainrings. Oval rings are never going to shift perfectly because of the variable front derailleur cage gap to the chainrings, but the DA 9200 front mech. is shockingly good. WIth SRAM mechanical and Etap, you gotta practice to nail the perfect torque and cadence for good shifting with oval rings, and then it does work well. But with DA 9200 it just works every time without paying any attention. I've always had a love/hate relationship with ovals, but now I don't hate. The bike previously had mechanical Red HRD, and the before/after weight is exactly the same - 7.2kg. Everything is silent as

L05A replaces L03A although my 9200 calipers were loaded with metal pads, L04C. Not sure why.
I just got round to pulling my pads as my front is rubbing :( . They are K03TI pads. So what is the standard here? or are they named differently for different markets? or is LO5A the same as KO3TI :?:

Thanks
Maybe it’s a supply issue thing, but included pads are all over the place it seems.

That seems to be the word. Too bad. That and a 52-36 would have been perfect for my needs.

Anyone see any issues using the new 12sp Dura-Ace crankset with an otherwise 11sp groupset? Which chain to use on such a setup? 11 or 12? I've seen good feedback on going the other way around with an 11sp crankset on a 12sp groupset because of the lack of availability but I actually have just the crankset and would like to use the 4iiii that I had installed on it.

Ultegra 11-34R
1. With dura Ace 9100 crank
2. With Rotor aldhu+chain ring
Both 50/34

No 1 have double shift problem, only when multishift enable

Both little noisy oN casette no matter i setup and trim, and when back pedaled it little stutter every few link

Tried change chain to kmc 12sp dlc, no luck. Worse stutter, so i go back with 8100 chain (which have really bad coating its show rust already)

All problem above i never experience on 11sp di2
And that really annoying, especially double shift
