I want to replace my Leader at some point, and I'm considering either another Leader (one of the models with fat-but-not-aero tubing), a Kilo TT or possibly one of these Visp frames. I'd really love a Cinelli Vigorelli but I feel that riding these expensive frames on the road to get around town is kinda terrible. Do the Visp frames come with headset? Are they integrated or just hidden?
