I own Colnago Master Piu. I believe it is a 1993. This bike has a Cinelli bottom bracket (raised lettering on the underside of the BB). Most of the pictures I have seen of Colnago bikes have the clover/club cutout on the underside of the BB. Does anyone know if there were certain models that had the Cinelli BB or did Colnago bikes use Cinelli BB during a certain time period?

By the way, my daughter has a 1984 Raleigh Team Professional with a Cinelli BB. Many of those didn't have the Cinelli BB either.
