I don’t know what is going on but I am having an absolute ‘mare. I have a Chorus 11 speed rear mech that came attached to the hanger when I bought it. I cannot get the T25 to budge and undo from the hanger in order to fit to my frame that has an incorporated hanger as part of the frame. I have tried soaking in pb blaster, and clamping the hanger in an axle with a qr but still can’t get it to budge. The T25 grips well and isn’t spinning, but it is hard to get that much torque through it but that doesn’t feel like the issue, but it is totally solid! Is there anything I am doing wrong beyond this?

Sounds like it’s seized, get heat on it and lots of it. Heat the hanger, not the derailleur. It will come off. You will want a vice to hold the hanger whilst it’s hot and to allow you to get the thing undone.

Cheers for the reply, I figured this might have been the case. Also wondering whether a ratchet/socket set with T25 head might provide better torque than the long-handled t25 I have access to!
