Oh sheesh, now I was confused too because the linked chart is wrong. I just measure mine, and it's the same as your, 62cm c-c along the TT, 63cm effective. I never used that chart anyways, it's either a preliminary version or it's simply a misprint, I'm guessing a misprint as the ETT jump from 56 to 60 frame should be 60.5 to 63, respectively. Every geo chart ever printed by Riv, and I've kept most if not all, show the 60cm Bomba @63cm ETT.
As for the tire clearance, those Supremes are what, in the 46-48cm range ? Yes, there's lots of room between the stays, and on the front you can fit a 2.2 without a fender. Between the blades is 63-64mm I think, where the fender would go. The chainstays and bridge however I'm not so sure, you'd have to either apply some widened calipers to guestimate the width and how forward, or just put a mounted tire in there. How much room is enough ? Enough that you don't crash and burn if caught in a "jam" !
