I have plenty of bikes, but if a Black 60's in a 55 or 56 presented itself... maybe. At this point, appropriate to sell off some to manage the purchase.
I read someplace (can't recall where now) what the tubing wall thicknesses were for Cinellis before the terms "SL" and "SP" had been coined. Up to 60cm or 61cm (not sure which), the dimensions match up exactly with what is now known as SL. Above that (like mine), the measurements match up exactly with SP.
