Marin San Quentin 20 2026
We took our Matt Jones-inspired Marin San Quentin and shrunk it down to fit 20â wheels. It's the perfect bike for kids who are ready for their first proper, hardcore hardtail mountain bike.
The Marin San Quentin 20â, just like the big kidâs version, 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. The San Quentin 20â will feel just like a âgrown upâ mountain bike to your little ripper, built with a stout Series 2 aluminum frame, 20â wheels, an SR Suntour XCM suspension fork, 8-speed Shimano drivetrain and kidâs specific hydraulic disc brakes.
