I want to kick this frame review back up for discussion in the forum. I have a 1999 Bianchi MegaPro Tri-bike. Frame size is 57cm seat tube with a 54cm top tube (650C wheels and 77 seat tube angle). I’m 6’ with long legs and short torso. The Bianchi Crono 57cm TT bike with a 55cm top tube (700C wheels and 74 seat tube angle) looks like it would fit me just right. Also isn’t this frame a few years old and just now being offered in the US. The defunct Team Coast road this TT frame in 2002.

I’d like some expert opinions on what I’m over looking between these 2 frames and also how big of a difference would my ride be in moving from a 77 to 74 seat tube angle. With my saddle height (BB - saddle) at 78cm, what is the over all difference in cockpit length between these 2 frames.
My big race this year is Ironman Canada and I’ll also be doing Wildflower and Muncie as I prepare for IMC.
