Details

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...
What better way to know a product will perform than having it proven on the FMB World Tour by Matt Jones? Check out the Red Bull-produced "Frames of Mind" to see the Alcatraz proving its mettle.

ONE-STOP SHOPPING
With the Alcatraz, you no longer need to scour the classifieds for a set of cranks and a single speed rear wheel — we took all of the frustration out of picking the correct parts to make sure you have the best bike right out of the box.
