Marin Alcatraz 1 Dirt Jump Bike - Blue/ Blue Fade

Season:2025

Brand:Marin

Code:7391160BLUFADE

The Alcatraz 1 allows the rider to follow in Matt Jones’ footsteps to build and personalize the best dirt jump bike possible. At home boosting your local 6-pack, ripping up the pump track, or hitting the local skate park the Alcatraz has what you need to take care of business.

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 suspension-corrected CrMo fork, front and rear Tektro disc brakes, Vee Tire rubber and plenty of bombproof Marin components. Best of all, it’s available in two frame sizes, regular and long.

  • 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 CHAINSTAYS - 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 dropouts — the standard in dirt jump technology for axle and dropout strength.
  • DIRT JUMP SPECIFIC SUSPENSION FORK - 100mm travel X-Fusion Slant DJ-specific fork with air spring, compression and rebound damping, and tapered alloy steerer tube.
