Powerslide Roadhog Speedbrake - the ORIGINAL for speedskates. The Powerslide Road Hog brake was the first-ever developed especially for marathon- and speedskates. It´s not traditional to create a brake for speed skates however, not every skater is a pro that knows what to do in case of emergency. The Road Hog brake can be used on the most common speed frames in the market. It has been specially developed for max. 4x110mm frame setups. The brake includes all necessary hardware. It takes about two minutes to assemble the brake. The brake pad is made of long-lasting and abrasion-resistant NR/SBR material, a mix of natural and synthetic rubber blends.
