Kathi: Thanks for the link for info on seat tube angles. I have the specs for my road bike around here somewhere, so I'll check and see what was prescribed for me. Assuming equal rider measurements, is there a difference in seat tube angle between road bikes and mountain bikes?



Cari, no there is not a difference. The length of the femur determines your seat tube angle. MY road and mtn bikes are 74.5 - 75 degrees. I have one mtn bike, my Voodoo which has a 72 degree st angle. I really notice the difference when I ride it, I'm to far away from the center of the bike to get good power on it. With a zero degree seatpost and my saddle as far forward as it will go, I can't get a good kops measurement, my femur is that short.

I specifically went for the Titus because of the st angle. There weren't many companies making a mtn bike with the steeper st angle which I need.
