After reading about how Cervelo is designed to be able to be ridden in a variety of seat angles without compromise I was wondering what is it about the design fo the bike which allows for this feature, along those lines, what is it about road bike design to allow for varieatin between seat angle (73 - 75 versus 75 - 78)

I have to say as I learn more about bike fit from this website I am more and more curious about the intersection of bike fit and bike design. There are things such as head tube, top tube, and set angle, which make sense but I would like to hear more about the other things in bike design and how they affect performance. Things like fork rake, head tube angle, chain stay length, top tube slope, bottom bracket design, tube diameter mixing...

I admire bikes such as the cervelo line... but what is it that makes them so good? For that matter what makes bikes like colnago so great... It sobviously not just about weight.

And Gerard if you are reading this... any chance that the red and white P3 will be released.
