The Samox Silver DJ-1 was developed for what dirt jump riders need – strength and durability to take the hits. The DJ-1s 2-piece, forged alloy design was developed to deliver standout durability and stiffness. That increased strength and stiffness is provided by the integrated cross channel structure on the inside of each crankarm. And to make installation and maintenance easier, Samox used their new FAS (fixed axle-bolt system) that allows the crankset to be easily installed using a single bolt instead of the more complicated, traditional pinch bolt design.
