Full suspension bikes have a system used to suspend the rider and all or part of the bicycle in order to protect them from the roughness of the terrain over which they travel. Diamondback utilizes its own unique suspension design called “Knuckle Box” suspension. Knuckle Box bikes employ Diamondback’s Knuckle Box suspension technology. The Knuckle Box, or bell crank, is the core of our single-pivot four-bar suspension platform. Optimally placed pivots equate to a low leverage ratio, and ultimately to superior pedaling efficiency and small-bump compliance. This equates for the perfect off road XC, trail, AM or gravity bike.
