I have a pair of blue anodized Nervar 165mm cranks that were on a Vitus track bike I recently bought. The frame is being sold off but I'm thinking if I should keep the cranks and use them or something. My Kalavinka (not keirin) is in desperate need of a pair of cranks you see but it has a Sugino 75 BB and I'm not sure if the Nervar cranks will fit. I've heard the Nervar cranks fits Campagnolo BB. What's the difference between the japanese and the italian BBs again? I'm so dumb I know but I really need to learn.

Do you have any recommendations for what I should do to get the most out of these cranks? I know they're not the pretties on the planet but I'd rather have a working Kalavinka than having it sitting in my living room unused.
