Details
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 before proudly releasing 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. The X Fusion Slant 26 DJ fork is the de facto choice for dirt jump aficionados, offering 100mm of travel for smooth landings. A forged alloy crankset and external bottom bracket form a lightweight and durable combo, while a set of Tektro hydraulic disc brakes make it easy to dial your approach speed. A suite of quality Marin components rounds out the build, including 750mm wide bars and a dirt jump specific saddle and seatpost.
