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.

DIRT JUMP INSPIRED FRAME STYLE

Taking cues from the Alcatraz, the San Quentin line up provides all the benefits of the DJ style with massive stand over, slick frame tubes, and a sexy paint job.

MODERN TRAIL GEOMETRY

The slack head tube angle paired with a steep seat tube angle create a ride that will fly uphill with perfect front wheel precision but then descend like it’s on rails. The balanced rider position thanks to the steep seat tube puts your weight between the wheels for impressive climbing and handling on flats, while the slack front end and short rear center help to pull you through the rough descents and corners with an intuitive feel.
