2019 Marin Alcatraz Dirt Jump Grey
The Alcatraz was designed from the ground up to be the best dirt jump hardtail you have ever ridden. Marin 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.

Use our size guide to see which size you need.
Disclamer: Height is a good general guideline to discover the appropriately sized frame, but bear in mind that it is only the first part of the bike fitting process; please also note that your inseam length and arm length will play a big part in your overall comfort. Other factors to consider are your torso length, lower back and hip flexibility, preferred riding position, core muscle strength, and experience with riding. All of our Bike Barn stores are qualified to help perform a bike fitting for you - stop in for a checkup if you are looking to upgrade your comfort level!
