Marin Alcatraz

Marin Alcatraz
This item is currently not available.


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 complete 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.
