Marin Alcatraz 1 Dirt Jump Bike

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.

Pump lips to get the ultimate boost with Alcatraz 1’s suspension-corrected CrMo rigid fork and fast-rolling Vee Tire XCV rubber. Tektro’s hydraulic rear disc brake amps up the stopping power and our ready-to-ride Marin parts will take a beating, so your bike is never out of action. Whether you’re finding the rhythm at your local six-pack, flowing at the pump track or sessioning your favorite park, the Alcatraz 1 takes care of business so you can focus on fun.

Built from 6061 aluminum, the Alcatraz’s Series 3 frame has carefully crafted tubes designed to handle the rough and tumble of your airborne antics.

Lightweight and tough, the frame has got what matters and none of the clutter that doesn’t. Internal cable routing keeps it looking sleek and cuts the rattle. Spend less time wrenching and more time sending with a 73mm BSA bottom bracket and horizontal dropouts, built with our custom chain tensioning device. ISCG 05 chain guide tabs are retention device ready – perfect for the wildest tricks.

Dial up or tone down the party vibes with two frame sizes – long or short. The short frame keeps you connected to your BMX roots, while the long frame offers a calmer ride and fits riders 5ft 11in or taller.
