ZING! the only problem i had was the cable routing for the brakes. we tried to push the cables through the little aero holes on the handlebars, but it put too much of a kink in them, so we just left them coming straight out of the hoods...not very "aero," or "clean looking" but then again, neither is the regular STI setup with the shifting cables flappin' out there in the breeze. i don't like road drops because i can never seem to get enough leverage on the brakes from the hoods, and that's where i keep my hands most of the time, so i figured, why the hell not? so far, i've put a bunch of miles on it, including some hill climbs and descents and sprints and distance rides with no comfort problems.
