The EK SRX Series Chains are equipped with QX-rings, surpassing traditional O-ring chains in performance. Laboratory tests demonstrate that QX-rings reduce friction by 40 percent, extending chain lifespan by up to 50 percent. Each chain link is designed with weight-saving holes, maintaining strength while minimizing rotating mass. These features combine to maximize rear wheel horsepower delivery and enhance throttle response.
