Alcatraz 1 26 2026

The Marin Alcatraz 1 is a pro-level dirt jump bike designed for pump tracks, trail jumps and skatepark sessions. Fast, tough and low-maintenance, it’s built for riders who want maximum boost with minimal fuss.

Up front, the suspension-corrected CrMo rigid fork delivers precise handling and direct feedback for pumping transitions and boosting lips. Paired with fast-rolling Vee Tire XCV tyres, the Alcatraz 1 carries speed effortlessly through berms, rollers and jump lines.

Control comes courtesy of a Tektro hydraulic rear disc brake, providing reliable, powerful stopping performance when you need to set up for the next feature. Durable, ready-to-ride Marin components are built to handle heavy landings and repeated sessions, keeping your bike running strong with minimal maintenance.

Whether you’re flowing your local pump track, sessioning dirt jumps or riding park, the Alcatraz 1 keeps things simple so you can focus on progression and fun.

At the heart of the Alcatraz 1 is Marin’s Series 3 6061 aluminium frame, engineered specifically for dirt jump and pump track riding. Carefully shaped tubing provides the strength to handle hard landings and technical tricks while keeping weight low for responsive handling.
