Assistir Assistir PobreTV. Mash is a group of friends: racers, artists, students, musicians, designers, and photographers, all connected through bikes. What started as a small video project and have grown into a team of racers, a line of bikes produced with Cinelli, and an outlet for friends to support each other through bikes. The accompanying video takes a narrower view than the book, focusing primarily on street-riding in San Francisco. With exceptional riding and up-close cinematography, the video captures the joy of riding track bikes in a city like SF and passes that excitement along.
