So my alloy BB shell/sleeve is starting to come away from the carbon frame, now at 2-3mm of play.
Any good recent experience of having this repaired?
I thought of getting a replacement frame, like an old 853, hoping it is stronger...

Following, since it may be looking deeper into carbon repairs, if I/the dealer can't get Cube to sell me a frame part...

I got a quote of £350-£450 from one place - just wondered what other experiences people had.

I had a frame repaired by fibre lyte
They did a good job and service and price were very good

Normally I'd say do it yourself but bb shells need to be square so may need jigging in place. Plus it's how the shell is bonded to the rest of the frame.
A proper solution would be machine the old shell out a bond in a new one.

If it was a cracked tube, easy cutting and sticking job.

My Scott CR1 had its BB shell unscrew with the cups 😬

It wasn't worth getting repaired so I glued it back in and rivetted also. I've put a HT2 chainset on it as this should hold the bearings in 😆 but haven't put serious miles on it since.

Brant was quoted as saying home epoxy is as good as factory, so why not try? Mine went together in a way that kept it aligned, not sure if bigdeans concerns are relevant to you.

Yes, i'm beginning to think some industrial strength glue is the way to go. Not much play atm so it could be possible to inject something around the sleeve, which will hold everything together.

don't know where you're based, but if you're near / in the the north west i can recommend target composites - they did a couple of structural and cosmetic frame repairs for me and did a great job. really good finish as well, could tell at all

Had a cracked downtube repaired by Carbon Bike Repairs in Surrey last year, cost around £350ish, held up fine so far. The only downside was the time it took but that was entirely down to them closing through covid lockdown

Yes, I tried Target, similar to my first quote. Seems like Fibre-lyte or CBT are the guys who will try bonding so thanks all. It's a fairly battered frame so I don't care for looks at this point.

Easy Composites is a great place to buy stuff if you want to try DIY. Making sure the cups were aligned would be my concern, so try to install BB cups and use a crank spindle to align them whilst the adhesive cures.
