HABS Sync Brake - advanced brake technology. In cooperation with Swiss scientists. we found out that heel brakes have a better function when the braking angle is higher. You will need to lift your toes a bit higher than usual. but then you are able to put your full body weight onto the brake. The higher pressure on the brake pads means you are able to stop faster. You can adjust the height of your brake pads to either customize it to fit your skate style or to optimize the performance when the pad is worn down. The brake pad is made of long-lasting and abrasion-resistant NR/SBR material. a mix of natural and synthetic rubber blends. The HABS Sync brake fits all skates featuring the Elite Syncro frame with 270mm length/3x110mm setup.
