Thanks for the opinion, you're probably right about that particular chinkshit tube not being strong enough (only 2mm wall thickness, I don't know what thickness or carbon layup seat tubes usually are)
But as for not fitting the hole, 31.6mm is a very precise measurement to find a premade tube for, which is why I asked. In theory it would be relatively simple to adapt a premade tube using some extra carbon weave and resin at the lugs and sanding it down if it overshot the dimensions, then epoxying the tube into the lugs. It would also act as butting increasing the overall strength. I just need to know what makes a good carbon tube for a frame, and the kind of stresses a seat tube is under, so I can find a premade one. Chink carbon is often absolutely fine - most carbon is chink anyway, just with more stringent quality control (i.e. checking down the frame's tube for deformities and correctly applying filler, non-issues with simple straight unpainted rolled tubes)
so what kind of tube do you think I'd need, and how would you make it fit my lug diameter?
