Includes 8 wheels, 16 Hybid Ceramic Bearings, 8 8mm Spacers, and 8 6mm Stepped Spacers (You only need 1 set of spacers depending on your skates, we inclue both as a courtesy). An all around wheel designed for the intermediate player looking for good speed, grip and wear on a variety of surfaces. These Shooter wheels are made right here in the USA by the family owned Labeda business. Amp Hybrid Ceramic bearings are like stimulants for your wheels. With this bearing you get the precision of ceramic and the durability of steel balls. The single Ceramic ball cleans debris and cools friction allowing for a longer lasting bearing.
