This guy (Giuliano Calore) is friggin sweet ! He rides with no bars, thus no brakes, and has descended a hill at 80 km p/h, unbelievable !! too bad his official website is only in italian.
Heres a video of him riding on an ice rink no handed, he also does some crazy maneuvers through a group of flags. 'Lest you start laughing, the guy is no slouch: his 1985 descent of the 48 hairpins of the Stelvio Pass on a bike with no handlebars or brakes took just over 27 min., averaging 80 km/h; in 1989 he climbed the Stelvio on a bike without handlebars or brakes in 1 hour and 17 minutes.(_via)'
