Marin Alcatraz 24" Youth Jump Bike
Marin Alcatraz 24" Youth Jump Bike
Marin have taken the Alcatraz 1 and scaled it down for smaller riders. Built upon the same tubing as the larger models, it features a 360mm reach, 69° headtube angle, and 72° seattube angle, with 369mm chainstays. A suspension-corrected rigid CrMo fork is designed to handle rough-and-rowdy riding, and a simple and stout single-speed drivetrain and Tektro mechanical disc brakes ensure a fun and safe ride.
SERIES 3 ALUMINUM FRAME
The Alcatraz features a 6061 Series 3 alloy frame, with a burly double butted tubesets for the best ride quality and stiffness, tapered headtubes for maximum strength on big jumps, and horizontal drop out with slotted IS disc brake tabs.
SHORT CHAINSTAYS
Marin have optimised the chainstay length of the Alcatraz to make sure you can have the shortest chainstays possible, giving you the ability to pop a wheelie or manual anywhere at anytime.
135X10MM HORIZONTAL DROPOUTS
The Alcatraz features 135x10mm horizontal dropouts — the standard in dirt jump technology for axle and dropout strength.

100mm travel X-Fusion Slant DJ-specific fork with air spring, compression and rebound damping, and tapered alloy steerer tube.
