The Alcatraz was designed from the ground up to be the best dirt jump bike you have ever ridden. Marin worked hand-in-hand with Matt Jones to develop a modern dirt jump frame, equally at home a your local pump track or skatepark. The Series 3 6061 aluminium frame is built for abuse, with burly double butted tube sets, a tapered headtube and 135x10mm horizontal dropouts with slotted IS disc brake tabs, and a chain tension device for either single speed or geared builds. Marin designed the Alcatraz with the shortest chainstays possible, giving you the ability to pop a wheelie or manual anywhere at any time. Spec’d with a 100mm travel X-Fusion Slant Dirt Jump specific fork with air spring, compression and rebound damping. Rolling on 26” Vee XCV dirt jump tyres and paired with hydraulic disc brakes. The Alcatraz has what you need to take care of business, whether it’s going big at your local your Dirt Jump track, boosting the pump track, or tearing it up at the local skate park.
