Overview
The JRZ Cobra Steel Runners are quickly taking over the game and giving players a step up on their competition. They have manufactured their steel with such precise accuracy that you'll get a consistent 10 ft. neutral pitch radius and high-quality product every time you purchase JRZ steel.
They also have a raised height of 22mm with added height to the toe and heel of the blades. This in turn provides even more sharpening life over standard steel, especially for the player who consistently profiles their blades. Players will also be able to maximize the lean in their turns and obtain more control when stopping and accelerating.
IW can have your skate blades delivered profiled, sharpened and game-ready! With custom blade profile options including Zuperior, Quad and Ellipse, you can immediately improve your speed, stability and agility compared to stock flat profiles. We also offer a wide range of sharpening options and when it is time for a fresh profile or edge tune-up, use our Express Mail-In Skate Blade Profiling and Sharpening service. Select your blade profile and sharpening hollow when you add a blade to your cart. Learn even more here.
