PU BLACK NILS EXTREME wheels are made of polyurethane. The most important parameters of the wheels are hardness and diameter. The hardness of the wheels determines both the comfort of driving and the adhesion to the ground. PU-82A wheels provide good shock absorption and perfect adaptation to any surface. The diameter of the wheels has a direct influence on the speed of the ride. Wheels with a larger diameter allow you to reach higher speeds, but do not guarantee as much maneuverability as wheels with a smaller diameter. ABEC 9 bearing, made of high-quality carbon steel that provides excellent hardness and strength. It is characterized by the lowest rolling resistance, which translates into the highest speed in the American Annular Bearing Engineering Committee standard, abbreviated as ABEC.
