This system is designed to reduce vibration to the riders hands.  This can be up to 300% more vibration damping than anti vibe cones alone.  The system also reduces the shock felt by the rider's hands, wrests, elbows, and shoulders from roots, rocks, ruts, square edges greatly lowering rider fatigue.
