I recently acquired a Lemond 853 frame with all the braze-ons shaved off in an attempt to make it more streamlined for fixie cult approval (@#$!%&*!!!!). It's a tragic thing I know but I am determined to breathe life into this frame and restore it at least to some semblance of functionality but here's the thing.....I've never brazed before. And cost of local builders repairing it is not an option. So...couple questions. JB-Weld. Strong enough for airplane wings, strong enough for bicycle braze-ons? The tensile strength of an average JB-Weld listed on their website is 3950 PSI. Is this a good number for downtube cable stops etc? I know it sounds extreme but... The other option that is slightly less cost prohibitive than taking it to a local builder would be to buy an eccentric hub (white Industries makes a good one for about $175) and build up a wheel for it but forever condemn the bike to singlespeed/fixiedom.
