SPEED - Amphetamine Ceramix Silver bearings are capable of high speeds with a high level of durability and longevity.

PRODUCTION - Silicon Nitride ceramic balls have the lowest tolerances to make sure your board doesn't slow you down.

FEATURES - Ceramic bearings are lighter and faster than steel ball bearings with an oil-free raceway. Additionally, ceramic bearings pulverize dirt and dust meaning they stay cleaner, longer.

PRE-LUBRICATED - Amphetamine bearings are pre-lubricated with Amp Synthetic Speed Oil and are ready to provide high speeds straight out of the package.

INCLUDES - 16 Bearings, 8 8mm Spacers, and 8 6mm Spacers which is enough for 8 wheels. We include BOTH 8mm and 6mm spacers, but you will only need to use on or the other based on the axle type that your skates feature.
