Marin Alcatraz Frame

The Alcatraz was designed from the ground up to be the best dirt jump hardtail 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 Alcatraz into the world. The 6061 aluminum frame is stiff and overbuilt for abuse, with a tapered headtube and 135x10mm horizontal dropouts with a chain tension device for either single speed or geared builds.

The Alcatraz frame allows the rider to follow in Matt Jones’ footsteps to build and personalize the best dirt jump bike possible. At home boosting your local 6-pack, ripping up the pump track, or hitting the local skate park, the Alcatraz has what you need to take care of business.
