pista bottom bracket question
I have an older (~'73) campy pista crankset, but no bottom bracket. Do I have to find an older campy bottom bracket, or will a newer one fit the same? Are there other modern (or older) cheaper brands that would work, such as miche? Or is the spindle taper specific to campy?
