Trim Option per Gear
Trimming is currently only possible simultanously for all gears. This sometimes leads to an optimal setup e.g. at lower gears while upper gears are suboptimal and would need additional trimming. Introducing a Trim-option per gear would give a perfect setup for the complete cassette.
If the derailleur hanger is non-damaged and the frame is designed to industry frame-fit specifications, trim position should not need to be tuned for individual cogs. That work is carefully completed by SRAM engineers as part of the cassette and rear derailleur design process.

Dear 6fcvhbn7cc@privaterelay.appleid.com,
Even new hangers can be bent, and often are! If you know someone with a hanger alignment tool (e.g. Park Tool DAG 2.2) borrow it and check the alignment or ask your lbs to check it.
In addition, some hangers are very soft and flex which causes shifting problems. I got fed up with my original hanger and replaced it with a "Wheels Manufacturing Derailleur Hanger" which is much stiffer than the original and solved my problems.

Good luck!

New hanger, new chain, new cassette, new AXS GX
... B screw set in SAG with 28 % ... 2nd gear perfect with Micro Adjust at 22, 10th gear perfect with Micro Adjust at 14 ...
What is wrong with the system? Is a wrong end stroke setting of the highest gear or the lowest gear responsible for this?
Happy to get feedback from you

2023 Specialized Levo Gen 3, 1300 miles, original GX derailleur always shifted perfectly, very slight barrel adjustment to tighten cable housing to correct shifting about 800 miles for normal housing wear. Just installed new GX AXS. Now, ether shifting from 1st (biggest) to 2nd, or 12th (smallest) to 11 is very slow, depending on microshift adjustment (only can adjust all gears). Microshift on app shows "18" setting is the best compromise so that only 12 to 11 shift is always noisy and very slow. Hanger is straight. B-Tension is per included white plastic guide. High and low stops are are 1/4 turn out from tight, as per instructions, chain length is still good. Very disappointing I cannot adjust just one cog at a time, an obvious design requirement failure. I hope it will "break-in" to shift as smooth as my original GX manual der. Very expensive for a neglectfully designed product.

I purchased the X01 axs upgrade ASSUMING that individual cog microadjustment would be possible. How could I predict that the engineers who designed the system would be so incompetent and ignorant as to create a system with an unnecesary virtual rigid cable and not allow for individual cog adjustment? I´m fuming!!!!
Last time purchasing SRAM for sure.

Hi All, The solution is blindingly simple, just buy Di2, or mechanical XTR, it's sooo much better. SRAM can get lost.

Reading this thread is hugely disappointing. I bought a brand new road bike about 5 months ago with SRAM Force eTap AXS 2 x 12. I have the same problem that everyone refers to. I have the 10-33t cassette and the best overall position I can achieve with the limited trim adjustment is most gears changing up and down reasonably well, very noisy on 14t cog and impossible to change up from 12t to 13t without changing up to 14t and then down again to 13t. Really poor and incredibly disappointing. I had manual Shimano Ultegra on my last bike and had far crisper gear changes across the range for the whole 4 years and 8,000 miles of ownership. I was excited to venture into electronic gears and the so called benefits but so far the experience is rubbish!
Either the cogs on the cassette are not all equidistant from each other or the so called tuning supplied by SRAM if off! It’s a £5k bike and has never had any knocks. What else can it be?
Could it be a faulty cassette? Any ideas would be much appreciated. -

All but one (second to largest cog) shift very smoothly. New bike. I just need micro adjustments on one gear. Please implement this feature.

For me everything worked perfectly in the beginning. Now eight months later I'm unable to adjust the derailleur to work in the whole gear range. Same problems as others here are experiencing. Two local bike shops have also tried with no success. Maybe some wear in the cassette, the derailleur or something else. Changed the hanger and chain, did not help. If only one could adjust the shift for individual gears... but no. Probably my last Sram AXS for the time being. Super annoyed.

erik@schmeling-online.de commented
Maybe the tolerance of the axs mounting is a little bit too big and this leeds to the need for different micro adjustment for each gear (I have six bikes with the axs, and none is really working perfect, and of course I am able to adjust the derailleur hanger). I assume they recognized their own problem and presented the transmission group. Took some time, because first they had to make sure that enough bikes are build with the UDH...so they will never improve the axs micro adjustment, it might prevent people from buying the transmission group...

It woulf reduce noise, and run smoother, saving watts.
I would happily pay extra for this feature (in app purchase, or something) -

How is this not a feature. It has nothing to do with hanger alignment. Their "engineered" parameters are just wrong. If it was done correctly, every gear would have an issue or none would with a bent hanger. Two separate bikes and three cassettes have had the same issue for me. NEW BIKES. You can easily see they messed up by figuring out the ideal Microshift setting for each gear. You'll see it moves around a lot and the range that works for some gears will be barely compatible with the range that works for other gears. It also looks like they have an issue with hysteresis as the ideal setting changes appreciably depending on up shift vs down shift. God I hope Shimano goes wireless. I'll drop AXS in a heart beat. My XTR drivetrain bike shifts SO MUCH better.

This feature isn't required in a perfect world, however we live in the real world.
The lack of this feature is the only reason I'm not putting AXS on my bike. Mountain bikes get damaged, I need to be able to correct for it.Other companies allow this, why is sram so backward?
I also run two drive trains, being able to have two configurations would be good (my DH wheel is 11sp).

I'm going to reference this post by the admin when i start making a ton of warranty claims because I'm unable to get the gears adjusted perfectly.
If we are unable to make the whole range of gears perfect, return the cassette and order a new one! This shouldn't be the solution, but if SRAM doesn't want to fix the problem then they have to eat the cost of returned product.

I raised this idea more than three years ago. Now, more than 150 positive votes and many supporting comments later, unfortunately still nothing has happened.
I just built up a new (in words: brand new!) Scale 2023 frame. - New UDH, SRAM only components. The mid gears make some noise. Removing this noise by the overall micro adjustment makes the higher gears not work properly. This is really annoying and could be solved if SRAM was willing to…!
Shimano, don‘t you listen to this thread? - Here are many potential customers waiting for your wireless derailleur and ready to order a user friendly solution. :-) -

This is an issue for me. Brand new bike. One specific gear is skipping on a stock 10-36t cassette combined with 33/46 chainring eTap AXS.
I went to fix this with microadjust and found out like everyone else that the way it works isn’t specific to the cog having an issue and therefor can’t fix an issue without creating another issue.
There are dozens of people with this same issue in your facebook group. Clearly your comment is either not true or your engineers or manufacturers are nor perfect and this feature is critical. Crazy to pay this much money for the illusion of a feature that you refuse to work on.

The admin says "If the derailleur hanger is non-damaged and the frame is designed to industry frame-fit specifications, trim position should not need to be tuned for individual cogs. That work is carefully completed by SRAM engineers as part of the cassette and rear derailleur design process."
Maybe the admin could explain the procedure when we're out on the trail, and the hanger gets bent ? Fitting another hanger in the dark at -2C is not really an option so after bending the hanger straight-ish I managed to get most gears working again and limp the 10 miles home but a trim option per gear would allow the problem gears to be adjusted out.
Luckily I have a Park Tool DAG 2.1, so, I could straighten the hanger properly once I got home but for riders who are at the mercy of their local bike shop then getting this fixed could take a week or two as the shops are too busy building new bikes and fixing punctures for the lazy.
If SRAM don't want to do this then please make the firmware publicly available and let some else do it.
