Gravel / Gravé / Gnarmac / Groad / ATB

the one that gets my goat is on the cursed Exploro because the rear one threads directly into the mech hanger which isn’t otherwise connected to the stays at all. So when you take it out to remove the rear wheel, the whole derailleur drops away which is supposed to be a good thing?!

Similar with Specialized, the hanger only have one bolt to attach it to the drop out, as well as having a slot for the wheel to sit, and the thread is in the frames, meaning it will move when you remove it, cue people thinking they fucked their bike up being unable to push the axle in.

Fortunately the wheel manufacturing version is better, but still.
