The Alcatraz was designed from the ground up to be the best dirt jump and slopestyle bike you've ever ridden. Marin worked closely with the legendary Matt Jones to determine 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 so you can do rad jumps without worrying if it can take the abuse, and comes with a tapered headtube and 135x10mm horizontal dropouts. Available as a complete bike, making for less time between you and throwing big whips and flips in your back yard or the bike park.

IF MATT JONES SAYS IT’S GOOD... What better way to know a product will perform than having it proven on the FMB World Tour by Matt Jones? Check out the Red Bull-produced “Frames of Mind” to see the Alcatraz proving its mettle.
“THE BEAUTY OF THIS PARTNERSHIP IS THAT THERE WERE
NO GUIDELINES TO WORK WITH OTHER THAN CREATING
THE ULTIMATE DIRT JUMP FRAME FOR MYSELF TO
PERFORM ON. THAT’S WHAT MAKES THE MARIN
ALCATRAZ SO SPECIAL TO ME.”
