Designed from the ground up to take on the skies. With Matt Jones’ expert insight, we made the Marin Alcatraz to be the very finest dirt jump, slopestyle, pump track and freestyle mountain bike you’ll ever boost.
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 drop outs. Available as a complete bike or a frame kit, so you can get the bike of your dreams for throwing big whips and flips.
We have optimized the chainstay length of the Alcatraz to make sure you can have the shortest chainstays possible, giving you the ability to pop a wheelie or manual anywhere at anytime.
135X10MM HORIZONTAL DROPOUTS
The Alcatraz features 135x10mm horizontal single speed only dropouts — the standard in dirt jump technology for axle and dropout strength.
AMBIDEXTROUS INTERNAL ROUTING
The location of the internal routing port allows for the rear brake to be located on the left or right hand side of the handlebars.
