Small Urban Brake - the universal brake for setups with a maximum of 4x80 mm. Many skates are sold without brakes. At Powerslide, we care about your safety and have developed several types of universal brakes that can be easily attached to your current skates. The Urban Brake can be used on the most common frames available on the market. The small size is specifically designed for setups of skates up to 4x80 mm or smaller. The brake includes all the necessary parts for installation. It takes about two minutes to install the brake. The brake pad is made from wear-resistant and durable NR/SBR material, a blend of natural and synthetic rubber.
