Marin Alcatraz Dirt Jump Frame Kit Long Purple is backordered and will ship as soon as it is back in stock.
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
