"The Marin San Quentin shreds the boundaries of the mountain bike genres - doing it all with a huge splash of big air, speed and style.Designed with the input of freeride legend Matt Jones, the San Quentin takes the DNA of our dirt-jumping Alcatraz and mutates it into a go-further and faster all-round, hardcore hardtail. Pedal all day in the hills, send it at the dirt jumps, carve the skatepark, go big in the bike park - it's all good on the San Quentin."
