Marin Alcatraz 1

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.
