I ride a large frame size and I've looked at quite a few NOS late 1980s/early 1990s Columbus tubing frames over the past couple years. During all my searching, I don't think I've ever seen an SLX frame larger than 59cm. I beleive the manufacturers in those days used "SLX-SP" or "SPX" for frames 60cm and larger. As I understand it, SLX-SP is/was a standard SLX tubset with SP tubing used for the seat tube. SPX is simply a version of SLX (i.e., with the helical reinforcement), but made with thicker tubing.

What might be the problem with a large SLX frame and a heavy rider? Probably too much flex of the frame.
