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 24" will feel just like a 'grown up' mountain bike to your little ripper, built with a stout Series 2 aluminum frame, 24" wheels, and for 2025/26, a new Manitou J Unit 100mm air suspension fork meaning more adjustability for lighter shredders.

Further updates include a one piece seatpost and saddle to allow for a lower standover and ride height, 1 x 9-speed Shimano Cues drivetrain, tubeless compatible tyres kid's specific hydraulic disc brakes.
