I'll be able to check it out next weekend. Considering that 10ah was enough for me for 30km. 15ach should be enough for 45km.
Please educate me.
edit: I'm not trying to be combative. I'm seriously interested in your opinion.

I'm assuming that was a rhetorical question.
How common is this hanger? Can I buy it from anywhere? lbs, ebay, aliex
It's described as a "standard" hanger. How would I even look it up to find?

It comes OE on the CEF50 frame. A "conventional" hanger spare can be purchased from Linda. It is $5 USD. I also posted this about 6 weeks ago on this thread. Got to keep up man.

I can't speak for Mike, but the UDH and UDH-T (for the new AXS) certainly is beefy, high tech, and packed with digital accuracy goodies. But damn, I thought my "old" AXS GX was pricey, the new stuff is mind-blowingly NOT cheap.
Both SRAM and Shimano engineering apparently feel that the rear triangle and specifically the driveside chaintstay is robust enough to resist torsional strain. Most have seen the impact testing that is impressive. Plus, pro Enduro racers have been using the longest (1 year plus) without any leaked photos of a shredded carbon chainstay, but the "conventional" hanger is softer alloy made to bend by design under impact, saving the stay and possibly rear mech too.
Still too early really to flesh out the true drawbacks (other than a high pricepoint and maybe greater weight). The whole problem is the rear mech. Some viable solutions that are now on their way such as a lightweight IGH, and the gearbox motor as stated earlier. IMHO the IGH should have been advanced way back in the 1980s, when mtbs were first invented. The bendable hanger/rear mech was an inherited appendage that worked well for road bikes in smooth, flat, predictable conditions, but not on dirt conditions, especially narrow techy singletrack.
I'm no purist, I like my AXS GX for damn accurate shifting. Fortunately, it will be cheaper now that the new UDH AXS is out. Saving future

I'm also glad it is not UDH, so I still can user cheaper RD

See it's already 35% cheaper for the upgrade kit.I'm also glad it is not UDH, so I still can user cheaper RD
UDH is totally backwards compatible, so i really don't understand what kind of advantage is to have some non universal solution?I'm also glad it is not UDH, so I still can user cheaper RD
If E10 is UDH, then it is very difficult to bend it. You can break the switch or the frame.
The only 'standard' derailleur hanger is the UDH and it works perfectly with all derailleurs, is cheap and available everywhere.
Not having a UDH is a major turnoff as I already have a high end '18 bike where the derailleur hangers, just aren't really available any longer.
There seems to be some confusion by some that UDH is only for Transmission. In actuality one must remove the UDH to run Eagle Transmission and this needs the exact cut out and spacing that UDH requires.

It doesn't matter to me, I can buy 10 pieces with a bike. It is important to me that now at the moment I can buy and enjoy the ride. UDH does not affect the quality of the frame and the pleasure of riding in any way. For me, the weight of the frame and the strength are important.

Yep. That's my understanding as well. But apparently the CEF50 is not a UDH compatible frame. It uses a conventional hanger.
So, with a UDH I can run my old AXS GX on a UDH but not on the new SRAM AXS-T ("T" for transmission). So, yes backward compatible for UDH but no UDH-T type.
Nor will the old school conventional hanger be compatible on UDH frame. Again, that is NOT backward compatible with the new AXS-T rear mech either. Technically, the UDH itself on a UDH frame is completely replaced with the T-type for the new AXS-T transmission.
See the current article below...it's short a quick and clear.
Note, I did re-word my earlier response and just edited it.

To clarify: from Linda her photo. The CEF50 conventional hanger. Ergo the CEF50 is NOT a UDH compatible frame. Hope this helps.🫡

My picture of the UDH I sent Linda 6 weeks ago to clarify the frame type. The CEF50 is NOT UDH compatible. So, this hanger will not fit on the CEF50 frame.
But if it was a UDH frame, I still could use my old AXS GX = backwards compatibility.
However, I couldn't run the New T-type AXS transmission on the non-UDH frame like the conventional CEF50 frame, so no backwards compatibility.
The new AXS is T-Type UDH only.
Further clarification hopefully.

Sure, there is utility in the UDH. But if the frame manufacturer doesn't make one to fit the frame nothing can be done about it.
I always buy a spare or two to have handy for that specific frame--nothing new. Yep it's a pain to track one down.
The UDH is available at most bike shops. Sure, convenient when it bends and you don't have an immediate spare handy.
The UDH just stages the new UDH-T that is only Eagle-T AXS drivetrain compatible.
Advantage: So, if you want the newest stuff, the UDH frame is the way to go.
No Advantage: If you don't want the newest stuff, the conventional hanger frame still works with the same old tech AXS. The frame manufacturer has the conventional hangers, so I can get at least one spare!
Disadvantage: having a rear derailleur at all. I want a lightweight IGH instead of the Eagle-T AXS. But in the meantime, I'm happy with old, now cheaper AXS.

SO I give up a cheap replaceable derailleur hanger that breaks if I get into a crash for one that rips off my whole chain/seat stays in a crash.
I am never going to buy SRAMS $1500 Transmission so why would I want UDH?

You are still confused.
UDH works with all derailleurs, but you can only run Transmission if the bike came with UDH. That is all.
The other stuff you are saying is gibberish (not trying to be rude).
Anyways, in this frame price range no UDH isn't a big deal and I have no intention of ever running Transmission on any bike. However, just as a matter of convenience and resale value I'd never buy a new high end MTB that didn't use UDH.
Transmission doesn't use a derailleur hanger at all in large part because many derailleur hangers flex and AXS has been flexing lesser hangers and causing shifting issues on some bikes, for years.
Also, the UDH is plastic and when it fails it mostly strips out and rotates. I carry a spare (without the bolt as the bolt doesn't fail) in my SWAT box and it only weighs 14 grams anyways.

Sorry NOT confused.
Agreed UDH works with any derailleur, except the new UDH-T AXS. You physically have to take off/remove the "old' UDH to use the new UDH-T derailleur/rear mech.
Right?

The direct mount T-type derailleur "hanger". It's true my first language is indeed English. But I'll try to speak more fluent, non-gibberish in the future for you.
There is no such thing as a 'new UDH-T AXS'.
You simply remove the UDH, and install the new Eagle Transmission in it's place. Transmission does not use a hanger at all, but does need the exact spacing left by the removal of the UDH to fit a frame correctly.

Damn dude. Need some caffeine to calm down.
Yep. As I said, and you said, remove UDH in order to use the direct mount T-type "hanger". So, correct no hanger at all.
Yes, guilty. I used the term "UDH-T AXS" to attempt to clarify that the new AXS only works with "T" for transmission. I didn't work for you. You got me. Let's move on.
So agreed! the new Eagle has no hanger...it's direct mount that uses the UDH frame.
Correct? Less gibberish for you? 🫡
