Threads on derailleur hanger

[Roseland triker]

I haven't tried that , can everyone else agree to bolt out from the frame rather than into it ?

Good luck.

I may have done the threads in

Solutions above: choice will depend on your expertise. But "any ideas" how you did the threads in? The hanger presumably bent/broke in your mashing. That won't have done 'em in.
NB Thread title misleading.

Whatever happened when I came off the hanger didn't even brake as I believe it's meant the whole hanger was still attached to the derailleur with the two screws inside

Go careful. Aluminium dropouts are not ideal
The whole back end strength is governed by the rear hub.

These or similar are widely available and should be appropriate, if I understand the problem correctly:



Establish the best size, then drill out the hanger and fit with the hex bolt head facing out. If you can get the size just right, you can make the hole exactly the same size as the female threaded sleeve; then heat the hanger gently and push in the sleeve from the back. When the hanger cools it will grip the sleeve tightly. With an aluminium frame, be very careful not to use excessive heat — the hanger will melt. A hair dryer should be fine (definitely not a paint stripper!).
