So I drilled it out. I don't think that any kind of adhesive, epoxy would be strong enough to hold this on. JB Weld? I dunno. I'll need a skinny threaded rod to run through there and 2 nuts on the end...which would prohibit me from using downtube shifters but I could put on the cable mounts for the brake/shift levers. And I am going to lightly sand and clear coat the carbon tubes because of the flaking.
