It's here, it's here, it's finally here! (new SRAM AXS drivetrain)

I find it amusing Internet posters think SRAM's engineers completely forgot to account for the derailer being attached to the frame.

"Oh shit, I knew we forgot something!!"

that’s not necessarily what posters ‘think’. You can’t cover all possible risks so some choices are to be made, and it’s not necessarily a call for the engineers to make. Not at SRAM, nor at Shimano or anywhere else.

They're trying to have 1 hanger for every bike on earth. All of the big companies use the UDH already so it's less proprietary than you'd think. The small guys are the ones screwing the standards up.

Do you have to pay to use the ‘standard’ hanger? If not adopting for the sake of not adopting then I would agree completely, if money were to be paid to SRAM to use it then it depends. Genuinely asking, I’ve no idea.

Purely from a mechanical point of view I would expect it to work better as it would be more precise and have less flex than a classics rd. Does it have to be AXS? The benefits could probably had with the peasants version as well.
 
Being an early adopter of AXS, I've had it on my bike for a bunch of years. I've smacked it on plenty of rocks, but never had to replace a hanger. I was anecdotally told by someone once that it has some mechanism to go limp when it detects a strike.

It's real. Hit your derailleur with a soft mallet, it goes limp and then returns. Pretty cool.

Open source, free to use.

IIRC, if you smack it hard enough it just overrides the servo motor, then the system will remember where it was and move it back.

The downside this new system is if you don't have a UDH compatible frame, you're SOL.

I have now lost count how many times I have smashed either of my AXS Rd's on rocks at speed....they are not unbreakable but more durable than another other RD I have owned....I cant believe some of the things I have clipped at speed in a race and it went right on working.

Isn't "failing" the whole point of a hanger? At least a replacement derailleur is only $550 if that rotating backward thing doesn't work when you smash it on a jagged rock.

its a nice theory, make the hanger the shear pin....In practice: I have 4 full suspension bikes...2 santa cruz's, 1 pivot, 1 c'dale....I have never been able to break a hanger on any of them....have broken several RDs tho...As you see when I ride thru the field of dreams...not even putting the RD thru the spokes will break the hanger. I suppose given their design/shape (they are not a round cylinder)...its not easy to make them shear off from hits coming from several possible directions.
 
The "standing" tests are a little disingenuous as they all seem to stand inline with the axle. There was one website where they claimed to purposefully bash the derailleur on a rock during a tight inside turn multiple times. No damage. I can confirm the release mechanism on the current AXS does work. The new derailleur can break free in two planes, so probably even better. $1,600 too rich for me.
