I recently bought a bike which had been built up from a new steel Italian frame from Ricci cycles in Cornwall. The bike had done only a few miles. Today I was riding when the cranks locked solid. The back wheel continues to roll forward no problem but it won't turn backwards of course. On looking at the crank area I see the bottom bracket has unscrewed itself several turns... I guess this caused the locking. See photos:

How do I repair this? I'm guessing I'll have to do it like this: 1 Undo the crank bolt (Centaur) with my 8mm allen key - hope this hasn't locked too. 2 Then I'll have to buy a crank extractor to take it off completely. 3 Buy a b bracket tool to screw it in again? Would this be right? I presume it unscrewed itself because the original DIYer didn't torque it up properly? Or perhaps, because its an Italian threaded Veloce bracket with a right-hand thread, it came loose because he didn't put some kind of loctite on the threads? Campag say that frames should have a drainage hole when using their brackets. I don't see one on this frame - is this a problem? Any help appreciated. Steve
