Overview
About this bike
Developed in conjunction with freeride legend Matt Jones and taking its name from the most rough and tumble piece of Marin County, the San Quentin collection lives up to the notoriety of the namesake maximum security California State Prison. Blending the strength an style of our Alcatraz dirt jump frame with the natural trail savvy of the best hardtails, the San Quentin family of aggressive trail hardtails is the perfect mash-up for the modern trail rider.
