Description

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 20" will feel just like a 'grown up' mountain bike to your little ripper, built with a stout Series 2 aluminum frame, 20" wheels, and a Manitou J Unit 80mm 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 8-speed clutch enabled MicroShift Acolyte drivetrain, tubeless compatible tires kid's specific hydraulic disc brakes.
