• Driving myself crazy here..

    I recently bought a frame with a 65mm Italian threaded shell and I can't seem to find a bottom bracket anywhere (apart from possibly an old campag record pista?). I initially fitted a standard 70mm bb but there's obviously overhang on the NDS, which I'm sure could be remedied with a locknut and spacers; problem there is that for some reason I can't seem to find Italian BB spacers (36mm dia?) anywhere.

    I'm hoping that my lack of BB knowledge isn't helping but this is making me even more grey at the temples so any help would be much appreciated!

    Sorry I can't help, but I'm curious as to how it ended up losing 5mm.

    Have you checked the crank clears the chainstay? You might need to spacer both sides.

    Is the shell still centred, ie has the shell been trimmed equally on both sides?
