ULTIMATE DIRT JUMPER
The Alcatraz was designed from the ground up to be the best dirt jump and slopestyle bike you have ever ridden. We worked hand-in-hand with Matt Jones to define the exact needs of a modern dirt jump frame, and are proud to release the complete Alcatraz into the world. The 6061 Series 3 aluminum alloy frame is stiff and overbuilt for abuse, with a tapered headtube and 135x10mm horizontal dropouts.
TWO FRAME SIZES
The Alcatraz is now offered in either short (385mm reach) or long (430mm reach) to better fit a wide range of riders.
ONE-STOP SHOPPING
With the Alcatraz, you no longer need to scour the classifieds or parts catalogs 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.
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.
