The Roll-Line Magnum FreeStyle Wheels (49D, 53D, 57D, and 60D) provide a durable, high-quality wheel used for various skating surfaces and preferred by international FreeStyle competitors for its grip and roll. Made with a strong, light, and precise design, it is able to withstand extreme abuse and maintain its close tolerances. The color of the wheel indicates its hardness for varying levels of grip on different surfaces. The softer the wheel, or lower Shore “D” hardness number, the more the grip and slightly less roll. The harder the wheel, or higher Shore “D” number, the more the roll, with slightly less grip.
