3 reasons the Diamondback Knuckle Box is the best suspension system
All of the scientific reasoning and engineering definitions in the world won’t help you understand just how well the platform performs and how much fun it is to ride. But we have attempted to sum it up in order to give you a better idea of what makes it work.
Diamondback Knuckle Box Effective Wheel Rate

Definition: Wheel Rate is the effective spring rate measured at the wheel. Fact: The wheel rate is the parameter that defines what the suspension will feel like when riding.

One of the advantages of a four bar linkage is that you have great control over the wheel rate. By manipulating the shape and position of the linkage you can achieve unlimited variations of the wheel rate. 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 a great bottom out protection.

Diamondback Knuckle Box Axel Path

Definition: Axle Path is the composite curve of the rear axle travel in relation to the BB shell.

Fact: The Axle Path is the parameter that defines pedal feedback of the suspension system.

The four bar layout of the Knuckle Box design achieves an optimized and neutral axle path. By manipulating the pivot locations of the Knuckle Box design we have come up with a design that has very low chain growth values, resulting in imperceptible to non-existent pedal feedback.

Diamondback Knuckle Box Low Center of Gravity
Low Center of Gravity

Definition: Center of gravity is the point where all the weight of an object is concentrated

Fact: A low center of gravity makes an object more stable.

When using a four bar layout you can locate the linkage anywhere you want. The position and shape of the Knuckle Box are designed with a low center of gravity in mind. Concentrating most of the mass low in the frame results in a lighter feeling, more balanced bike with increased maneuverability.
