Looks awesome! Reminds me of the old Specialized derailleur buddy. It's obviously printed, but out of what material? Can't tell if it's metal or plastic.

Material is aluminum (AlSi10Mg), M4 bolt passes through the derailleur bolt from the back and threads in to secure it. If it seems there would be interest I'll make some available.

Should prevent the hanger from bending quite a bit. Clean up the design to make it CNC millable? I'm guessing there's a post going into the derailleur, so maybe make it a two part item?

Nice job, I would buy one for sure if you made a batch

Think you could do something with Shimano derailleurs? I would rather not have to replace the XT derailleur on my parkduro bike every few months.

Can be made millable, but had fun with the shape since it didn't have to be. SLM is a great process - only advantage i see of milling is ability to anodize colors - AlSi10Mg is highly corrosion resistant and strong, but it's silver (conveniently the silver goes with the derailleur cage and decals quite well).
Titanium is an option - with the fun anodization options that brings, but much more expensive for same utility so aside from a small number of misguided humans (like myself - purple Ti for me) aluminum makes more sense.
There's a small post as you were picturing - threaded so the derailleur doesn't need any modification (threads through not just the nub is threaded).

I'd buy that twice (and I don't even have an UDH compatible frame yet)
Replaceable derailleur hangers are designed to break to save your frame not your derailleur.
Are we talking about the same thing here?
the UDH, is in fact a Universal Derailleur hanger, that is designed to be sacrificial.
the new SRAM transmission mounting is designed in much the same way, with replaceable/rebuildable parts.
What has been designed by @kroe can be thought to be a stiffner of sorts, that could also "shrug" off impacts, similar to what both specialized and Syntace has done in the past, but obviously not for UDH equpiied bikes, which would make his design novel in that it could be used on any bike with that uses a UDH.

You’ve updated/re-invented the North Shore Billet hanger banger! I used to run them on my street trails bike in the early 2000’s. I had a Chris King 135mm non disc hub upgraded to fun bolts with the outer washer removed to hold the hanger banger on. It was a near perfect fit. Neat! Specialized later copied the design.

Does that clear it up, or am i missing something?
The UDH is sacrificial, but it doesn't protect the derailleur it protects the frame.
Sometime people think the replaceable derailleur hanger is to protect the derailleur. It is not, it protects the frame.
One of the potential downsides to transmission is that without a sacrificial derailleur hanger, there is more potential to damage the frame (or hub) in a crash.
It's designed to rotate to hopefully move the derailleur out of the way.
Exactly, UDH rotates.
Linking the derailleur to the stiff and strong UDH axle assembly strengthens and stiffens. This could change failure modes like many bike modifications (including a full mount derailleur), but the UDH dropout will still rotate on impact like it should, and the brace does not stick out past the derailleur body (it's not a new snaggy bit).

Great idea and execution! Been thinking about this for Shimano derailleurs for awhile.
Very cool.

Yes, I just haven't measured one yet - pretty much the same thing just needs adjusting for bolt length.
love to have one for my e-bike.
I would love to get one once you make the measurements. DM me your venmo or something, would love to get one later on.
Ah, sneaky. No need to do a two parter on this one.
That's super neat, a great innovation! it would shield my derailleur from 80% of the strikes on the side of it
very cool I'd buy one if it's under 20$ cad @luckilycmoi on instagram

Guy is already lowballing before release lmao

Kinda like when a remake of a legendary movie comes out.....it's inevitably going to suck.
Great idea but not new at all. That already existed 15+ years ago and e.g. Syntace offered it for their bikes.
But isnt the UDH designed to break to save your derailleur?
lol, Vital gets more and more Pinkbike-ish. When presenting facts (like in the tire weight discussion) or prior art (here), you get downvoted.
Specialized also had them on the Demo for years.
It was already covered that this isn't a new concept, Specialized sold it as well, what is new is making for UDH so all bikes can use it.
Down get so upset
No.
