|Ok, on New Years Day I had a minor crash in which a brand new wheelset (Campy Scirocco) was ruined. The front is destroyed; the rear is fine, as is almost everything else. Here is where it gets tricky. Somehow, the braze on water bottle bolts were ripped out of the frame. I tried a metal epoxy; it didn't really work. Besides the obvious answer of having the bolts brazed back in, how would you attempt to fix this at a reasonable price. I appreciate your time and thought.

|If the bolts were ripped out of the bosses, I say do what rwbawdley says and clean the holes and tap them to the next size up. If the bosses were ripped off (when I think about it, it sounds unlikely) then you have to have them brazed back on.

|same type of fastener used on modern thin wall frames like my starlight.
hit mcmaster-carr's website (mcmaster.com) and search for item number 91230A221, $5 per 10 pack. should be exactly what the doctor ordered.
the installation tool is part number 98590A100, not cheap at $53 tho. with a bit of creativity you can seat the inserts without the manufacturer's install tool. you can cobble a servicible one together with using a bolt, a star washer, a flat washer, and a strip of scrap metal w/ a 4mm hole drilled in one end. experiment on some scrap metal stock using some of the spare inserts before going for the gold on your frame.
if you don't trust yourself to pull it off i'm sure you could find a metal fabrication shop in your area that already has the goods, or if you live in new mexico give me a holler

|Most waterbottle bosses are riveted in in the first place. I'd just get a new rivet and re-do the job - it should work perfectly well.|

|Talk to your mechanic. He very well may have a Riv-nut tool. I have a mechanic-friend that does...
