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.
TWO FRAME SIZES
Newly updated for 2022, the Alcatraz is now offered in either short (385mm reach) or long (430mm reach) to better fit a wider range of riders.
FUN, STRONG, AWESOME
Usually in life you can't get everything you need, but with the Alcatraz dirt jumper you can – a fun, burly bike that will let you explore what is possible with two wheels.
IF MATT JONES SAYS IT'S GOOD...
