Thanks for that. The 724 is carbon? And you have the 12mm axle on the rear? Is the metal insert that is threaded bonded to the carbon of the stay, or does it just sit in there?
Mine is a bit different, there’s no threads to screw a 12mm axle in, so I guess there must be a replaceable nut/insert when 12mm is used, which I don’t have. Instead, theres a stepdown insert sitting in the chainstay on the non-drive side, to space the hole down from 12mm to 5mm, for a conventional qr, and on the drive side the mech hanger is machined to perform the same task. On the outside of the chainstay there’s a recess to hold a threaded nut, presumably either 5mm or 12mm inside diameter depending on the axle being used. I’ve lost that nut, which is for 5mm, and am after either a replacement, or the whole assembly to run it with a 12mm axle, which must use a different mech hanger.
