Product Details - Marin Alcatraz 1 Dirt Jump Hardtail Mtb Bike 2026 Blue Green Fade
The Marin Alcatraz 1 is a tough, no-nonsense dirt jump bike built for riders who want to push their skills without breaking the bank.
Inspired by Marin's pro-level Alcatraz range and developed with input from Matt Jones, it delivers a responsive, playful ride that's perfect for pump tracks, dirt jumps and street sessions. Its Series 3 aluminium frame is built to handle hard riding while staying light and agile, with short chainstays and a compact geometry that make manuals, jumps and tricks feel natural and controlled. A durable Cro-Mo fork keeps things simple and strong, while quality components ensure it's ready to ride straight out of the box. A hydraulic rear disc brake provides dependable stopping power and control, while the single-speed drivetrain keeps maintenance low and reliability high. With wide tyres and a solid wheelset, the Alcatraz 1 is ready for everything from skateparks to trails. Built for progression and packed with value, the Alcatraz 1 is the ideal entry point into dirt jumping and freestyle riding.
