People seem to say that the "relaxed" road bike geometry is better for longer road riding than "twitchy" track geometry. However, unless I'm wrong, I think a lot of triathlon bikes have even steeper seat tube angles than track bikes do, and people ride triathlon bikes for pretty long distances on the road. What am I missing? The reason I ask, is that I have a surly steamroller with some pretty nice components, and sometime in the future I might like to get a nice used lugged track frame to use with some of my present stuff. I really like how the steamroller rides though. I don't want to end up with something that looks good but really doesn't ride well.
