The Alcatraz was designed from the ground up to be the best dirt jump and slopestyle bike you have ever ridden. We worked hand- in-hand with Matt Jones to define the exact needs of a modern dirt jump frame, and are proud to release the complete Alcatraz into the world. The 6061 Series 3 aluminum alloy frame is stiff and overbuilt for abuse, with a tapered headtube and 135x10mm horizontal drop outs. Available solely as a complete bike, so there is less time between you and throwing big whips and flips.
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.
We have optimized 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.
The bike comes as a single speed, but we added an ISCG tab if you want to protect you chainring, or if you want to change out to gears and run a chain guide.
135X10MM HORIZONTAL DROPOUTS
The Alcatraz features 135x10mm horizontal dropouts — the standard in dirt jump technology for axle and dropout strength.
