Wherever you're reading that, the Pista BB is probably labeled "track only" because the 111mm spindle length may not be compatible with any of Campy's road cranks.

You can use any ISO square tapered BB having a spindle length of 111mm (or close) with that crankset, it doesn't need to be a Campy BB. For example, a Phil Wood 110.5mm ISO will also work just fine.
