ZENsystem Slip changes the direction of the pedal stroke near the bottom blind spot. Adjusting the angle of the pedal face compared to the shoe sole will provide the fastest transition and boost your cadence. All this without any change in posture.ZENsystem Slip is a patented technology. It fits between the normal cleat and the sole of the shoe. Despite the addition at the bottom of the shoe, the position of the foot remains exactly the same while the Zenslip helps you over the transition from dead center. Cycling will feel exactly the same during rotation (at 30° - 150°), but at dead center (at 150° - 210°) you will feel a 'slipping' effect that helps you get over the dead center. The effect will be most noticeable when climbing due to the angle of inclination of the bicycle. You will clearly notice the acceleration over dead center. In addition, you will also feel less of an urge to get out of the saddle while climbing. You will notice the acceleration (slippage) while climbing at 140° and will continue until after dead center up to 215°.
