MARIN-25 ALCATRAZ 1- BLUE FADE-Dirt Jumper
The Alcatraz 1 is the entry level into the Matt Jones matrix, the base to which, if they wish, the rider can build from 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 1 allows you to take care of business in a solid and reliable package.
The Series 3 aluminum frame is built for hard knocks and stiff enough for lightning-fast acceleration. Short chainstays make manuals easy whilst little details like ambidextrous cable routing means you can run your brake on the left or right of the bars. There’s a suspension-corrected CrMo fork to keep the angles as Matt designed, 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.
