If you look at the Shimano Techdocs, specifically the Exploded Views (EV's), there are many different part numbers, and even with the Road derailleurs, there are different parts for Mech & Di2 - what the difference is, no idea. Sometimes it's the material (e.g. the R7000 and R8000 are copmpatible, but one is steel vs 1 is alloy)StiffWeenies wrote: ↑Tue Oct 26, 2021 4:36 pmThank you. Do you also know if the Shimano Road DM hanger design is the same as the one on their 11 speed MTB derailleurs? I can theoretically attach a XTR M9000 RD via Sigeyi's DM hanger to a compatible road frame?

Thanks for the suggestion, it seems that M9000 and R9100 are different. I'll have to sit down and do some more digging on the other models later to try and find commonalities.MichaelB wrote: ↑Tue Oct 26, 2021 11:26 pmIf you look at the Shimano Techdocs, specifically the Exploded Views (EV's), there are many different part numbers, and even with the Road derailleurs, there are different parts for Mech & Di2 - what the difference is, no idea.

In the mean time, I shot an email to Wolf Tooth asking if the DM bolt holes are the same on their Goatlink 11 and Roadlink DM. If they are, I think I have a shot at making it all work.

The Shimano Mountain Direct-Mount standard (used on 10s & 11s group) is different than the Road Direct Mount standard (introduced with R9100/R8000)
The most obvious diffrence between the two is the angle of the stop for the b-tension bolt. You can see the difference with these 2 paragon machine works hanger:

Bummer. Thank you for the answer though. I guess I'll just go the custom CNC route and make my own frame specific DM RD hanger for Shimano MTB. I thought I could just bolt up a MTB DM RD to a Sigeyi hanger but life's never that easy.1llum4 wrote: ↑Wed Oct 27, 2021 2:39 pmThe Shimano Mountain Direct-Mount standard (used on 10s & 11s group) is different than the Road Direct Mount standard (introduced with R9100/R8000)

The Road DM hanger for Shimano is longer than the MTB hanger. The road hanger is 47.4mm from the center of the skewer bolt to the center of the RD mount bolt. The MTB hanger is 44.7mm Those dimensions are from the hangers produced by Paragon Machine Works to Shimano's specs. I have enclosed a PDF of their hangers.
I also enclosed a Shimano diagram for the dimensions they spec for DM.

Thank you. Your reply gives me more confidence in making it all work out. Surely that 2.7mm difference can be compensated for by adjusting the RD?BdaGhisallo wrote: ↑Fri Oct 29, 2021 10:40 amStiffWeenies wrote: ↑Tue Oct 26, 2021 4:36 pmThank you.
