Knuckle Box Suspension System
All the scientific reasoning and engineering jargon in the world won't help you understand how the Knuckle Box suspension system performs. To truly appreciate how the system works, you really need to ride one. However, all bikes with Knuckle Box systems do share some common traits. The first is an optimized wheel rate, the parameter that defines what the suspension will feel like when riding. The Knuckle Box is shaped in such a way that the wheel rate starts off linear and finishes slightly progressive. This results in great small bump compliance, more perceived travel, and great bottom-out protection. Riders will also enjoy an optimized axle path--the parameter that defines your pedal feedback. By manipulating the pivot locations of the Knuckle Box system, Diamondback has come up with a design that produces very low chain-growth values, so you barely feel any pedal feedback at all. Finally, the Knuckle Box offers a low center of gravity. With most of the mass concentrated low in the frame, the bike feels lighter and more balanced, and maneuvers better than other mountain bikes.

The Mission 3's Knuckle Box suspension system helps the bike feel light, smooth, and maneuverable.
