Designed in conjunction with Marin ambassador/MTB legend Matt Jones, the Alcatraz collection is ready for dirt jumps, pump tracks, skateparks, slopestyle, or virtually anything you throw at it.
The Series 3 aluminum frame is built for the hard knocks and is stiff enough for lightning-fast acceleration and tough enough for the heavy hits. Short stays keep manuals easy and ambidextrous cable routing means you can run your brake on the left or right of the bars. There’s a 100mm Manitou Expert coil fork, front and rear Shimano hydraulic disc brakes, Vee Tire rubber and plenty of bombproof Marin components. Best of all, it’s available in two frame sizes, regular and long.
Technology
Series 3 Aluminum Frame
The Alcatraz features a 6061 Series 3 alloy frame, with a burly double butted tubesets for the best ride quality and stiffness, tapered headtubes for maximum strength on big jumps, and horizontal drop out with slotted IS disc brake tabs.
Short Chainstay
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.
135 x 10mm Horizontal Dropout
The Alcatraz features 135 x 10mm horizontal dropouts — the standard in dirt jump technology for axle and dropout strength.
Dirt Jump Suspension Fork
100mm travel X-Fusion Slant DJ-specific fork with air spring, compression and rebound damping, and tapered alloy steerer tube.
