Jonny is definitely infinitely more experienced than me but I do know several companies making carbon bike frames and parts use 3M DP420 or if you want a longer workable time before it sets DP460

You need a toughened structural adhesive with a high shear strength. Ideally you want to be able to get the rails all the way out and clean out any old adhesive first.

I was going to say Scotch Weld 9323 but it's dead expensive. Those two have a shear strength fairly close to 9323 so I'd give either of them a go.

9323: https://www.3m.co.uk/3M/en_GB/p/d/b40066445/You might find some cheap on eBay which is close to or slightly over its use by date. It'll still be fine.

As you seem to know about these things, I have the Tune Kom Vorr saddle where the rails have come away from the shell in one area. Could you direct me towards the right adhesive to be using? Two part epoxy just cracked again right away.
