I'm currently riding a 2002 steel frame KHS Flite 500 which at some point prior to my ownership of it was upgraded to a Campy Xenon grouppo. I'll commute 40km per day on that bike when it's sunny, with longer rides up to 150km semi-regularly. I don't race, but I wouldn't want to rule that out at some point - I'm still pretty new to cycling semi-seriously. I would like a ride that's comfortable enough for gran fondo distances, but aggressive enough to let me ride as fast as I want - I've learned from having to commute on a hybrid when it's raining that I love riding best when I'm going fast. Thoughts?
