That's interesting! Let us know if you find out for sure. The seat tube angle on my Bianchi is 74, which was one of the reasons I bought that bike. But am now thinking of getting something a little lighter and faster as I contemplate Olympic length races next season, so I have been pondering all this just lately.
What's ALSO interesting is that you are the second coach/PT in less than 24 hours to say---not sure that a tri bike is better than a road bike for races. Especially around here, where some of the courses are pretty hilly.
"My predominant feeling is one of gratitude. I have loved and been loved;I have been given much and I have given something in return...Above all, I have been a sentient being, a thinking animal, on this beautiful planet, and that in itself has been an enormous privilege and an adventure." O. Sacks
