The Marin Alcatraz 2 Marin's pro-level dirt jump and pump track bike built for riders who want bigger airtime, smoother landings and total confidence on every line. Whether you’re boosting jumps, throwing tricks or charging berms, the Alcatraz 2 is designed to push your progression further.

Up front, the Manitou Circus Expert fork with 100mm travel delivers proven dirt jump performance, soaking up heavy landings while maintaining precise control. The PNW Range handlebars with 38mm rise provide the perfect balance of comfort and leverage, reducing hand fatigue on harsh impacts while giving you confident front-end control.

When it’s time to scrub speed, the Tektro four-piston hydraulic rear disc brake delivers powerful, consistent stopping performance — ideal for technical jump lines and steep roll-ins.

At the core of the Alcatraz 2 is Marin’s Series 3 6061 aluminium frame, engineered specifically for dirt jump riding. Carefully shaped tubing delivers exceptional strength-to-weight performance, built to withstand hard landings, spins and repeated sessions at the trails or skatepark.
