Thanks for the info, guys. FWIW, mine measures out to about 56cm, but since the Pista wasn't offered as a 56 (that I'm aware of), it must be a 57. Double-butted CroMoly tubing. I'll post some pictures later today.

Now I have to commit to selling it. We finally live within driving distance of a nice velodrome, but alas, I think my dreams of track glory are behind me...

Thanks again.
Scott
