Product Details

Description

The Alcatraz was designed from the ground up to be the best dirt jump and slopestyle bike you have ever ridden. Marin 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. 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 Alcatraz 1 offers up a Series 3 aluminum frame built for the hard knocks, it’s 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 mechanical disc brakes, Marin Custom Extrusion 26” Rims rolling on Vee Tire 2.25” rubber and plenty of bombproof Marin components. Best of all, it’s available in two frame sizes, regular and long to suit all rider heights.
