• well paul components hub are a 44mm chainline, when usually it's a 42mm and when a company gives a reccomendation for bb length it's based on getting a 42mm chainline.

    Miche cranks are bit of guesswork now, they used to be 107mm iso for a 42mm chainline, if yours are the 107mm iso, you'll need 111mm iso bb to work perfectly with the paul hubs as the extra 4mm will put the cranks an extra 2mm out on each side

    However miche changed their cranks recently to a 107mm jis, and didn't tell anybody, or put any new markings on, which is a bit of a fucker for the likes of you.

    At a guess though, yours are the iso version so look for a 111mm iso bb, not tifosi or token though as they're shit, anything campag will do the job
