6/17/2024 4:37am Yeah, there is an extra part pictured - the brace is something I designed - replaces the washer on UDH dropout and bolts through the back of the derailleur bolt. That part is not needed for this to work. The part I ground off was done with an angle grinder - there are more precise ways, but it makes zero...

6/17/2024 4:31am Yes, transmission cassette chain, eagle elsewhere.

6/16/2024 5:00pm SRAM indicates it does not work, my angle grinder believes otherwise. Grinding non-critical centering material off a UDH dropout provided required clearance between the smallest cog and dropout. Shifts great - especially improved shifting to harder gears and under load. X0 (XS-1295) cassette, XX t-type chain, XX1 Eagle mechanical shifter and derailleur.

This looks pretty good, but I'm left wondering how many people can stand on it?

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. Does that...

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

12/22/2023 7:41am Neat, hadn't seen that before. UDH makes the concept more practical, since it standardizes position of the derailleur relative to the axle. Forward we regress!

12/22/2023 7:36am 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).

12/20/2023 12:47pm Yes, I just haven't measured one yet - pretty much the same thing just needs adjusting for bolt length.

12/20/2023 12:40pm 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...

12/20/2023 10:45am 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.

12/20/2023 10:31am Eagle derailleur was feeling left out - so I made a thing - replaces the washer on a standard UDH dropout with a "Brace" that links the rear derailleur for strength and stiffness.
