The Marin Alcatraz 2 26" Jump Bike is a purpose-built dirt jump machine designed for big moves, precise control and dependable durability on demanding jump lines. Its Series 3 6061 aluminium frame delivers the ideal balance of strength and low weight, while the Manitou Circus Expert fork provides 100mm of controlled travel to smooth harsh landings. With short chainstays for quick manuals, a stable jump-focused geometry and a carefully selected component build, the Alcatraz 2 gives riders the confidence to push progression without unnecessary complexity or maintenance.

Key Features and Benefits:

• Series 3 6061 aluminium frame: Carefully shaped aluminium tubing provides high strength while keeping overall weight low. This strong yet responsive frame construction handles repeated hard landings and aggressive riding while maintaining the agility needed for spins, manuals and technical jump lines.
• Manitou Circus Expert fork with 100mm travel: A purpose-built dirt jump fork designed to absorb heavy impacts and harsh landings. The coil spring design delivers predictable suspension performance that keeps the front wheel controlled and stable when landing large jumps or technical tricks.
• Short chainstay dirt jump geometry: Compact rear triangle design places the rear wheel closer to the rider, making it easier to lift the front wheel and control manuals. This responsive geometry improves bike handling during jumps, spins and quick line adjustments.
• Tektro HD-M535 four-piston hydraulic disc brake: A powerful four-piston rear brake system delivers strong and consistent braking performance. The increased braking force helps riders control speed precisely before jumps or technical features.
• PNW Range handlebars with 38mm rise and Marin CNC stem: Wide 800mm handlebars with increased rise improve rider leverage and control. This cockpit setup reduces impact through the hands and improves stability when landing jumps or correcting body position mid-air.
• Horizontal dropouts with Marin chain tension device: Adjustable rear dropouts allow precise chain tension without using a derailleur. This simple and reliable drivetrain setup reduces maintenance while ensuring consistent power transfer and chain stability during hard riding.

The Alcatraz 2 focuses on durability, control and simplicity so riders can focus on progression. Its strong aluminium frame absorbs the abuse of repeated jump sessions, while the purpose-built suspension and stable cockpit maintain control during demanding tricks. A simple single-speed drivetrain, threaded bottom bracket and sealed bearings reduce maintenance demands and keep the bike running smoothly between sessions.

For riders who want a reliable jump bike that supports skill progression and consistent performance, the Marin Alcatraz 2 delivers a balanced blend of strength, control and low maintenance. It is ready for the pump track, dirt jumps or street riding whenever the next session begins.
