The Revision Variant Steel Hockey Wheels come with all the bells and whistles from the previous Variant Steel's but with an improved color scheme. The pro-level urethane combined with their Torus Technology provides excellent grip while turning and increased raw speed. These wheels offer a 78A hardness which is unusual for an indoor roller hockey wheel but they are designed for the player who puts a lot of pressure on their wheels when they skate. This will allow the wheels to last longer while still providing excellent grip through turns. Revision offers a 30-day guarantee on these wheels because they're sure you're going to love them! Ideal playing surfaces: Sport Court, Hockey Tiles, Wood, Smooth Concrete Made in the USA Wheel Hardness Body Weight Level of Play Surface 78A Up to 220 lbs Performance Indoor
