so BB 95 bearing was seized into alloy cup and both drifted out together i have now seperated them so what loctite or other 'glue' to refit cup to frame. Guess it needs to be a 'permanent 'bond,
Any suggestions please

Wait for the better informed but I suspect you will want something along the likes of araldite.

See what others say before committing though!😁

I used something similar on my carbon Anthem, I'll have to check what one, then fitted a screw together wheels manufacturing bb.

I would be concerned about alignment rather than just sticking it in so I would talk to one of the composite repair specialists. A misaligned bearing seat would cause premature wear / annoyingly creak.

Epoxy is the likely solution. Normally it would be a version by loctite or araldite. I recently used some evostickn in testing that was exceptional. German, so cant remember the brand. Adhesion/tensile strength of 20+MPA.

As above though this won't help with alignment. It also still might not be enough to prevent it happening again. A sleeve might be better. Fiberlyte are good for repair they might be able to advise.

Plexus MA300 if you want to do it properly.

The token ninja bracket I mentioned guarantees perfect alignment and is considerably more looking lasting than standard press fit
