Slightly weird question, a while ago I bought an 11sp SRAM RD on eBay that was going cheap as a last minute spot. When it arrived there was a little finger sized hole where I’d expect the bolt to be that mounts the mech to your hanger. I went back and checked the listing, and it had actually been photographed like that but without making it super obvious.
The mech seems fine otherwise, so I’m ok with me not having looked carefully, but I would like to use it! Does anyone know the proper name for this part and where I can find it? Additionally, is it an option to rob one from an old X7 RD I have kicking around?
Thanks!
