Thanks...please keep me posted on your experience with MAX. I also ride large frames (59-60cm, center to center). Regarding Columbus SL, I beleive we share the same view...it's a comfortable ride...I think Columbus SL is under-rated as a "bottom of the line tubing" (i.e., it seems SLX is always more desireable). My next build is a SLX-SP, so I'll finally be able to do somewhat of a comparison.
