Alcatraz Dirt Jump YELLOW os

Season:2025

Brand:Marin

Code:739060001

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.
