Marin San Quentin One 27.5” (650b)







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