SONIC ABEC 9 Inline Skate Bearings

Sonic ABEC9 Inline Skate Bearings are the top of the line ABEC offering. These bearings use the highest-level of precision during the manufacturing process. Combined with the heat-treated and honed premium Japanese SUJ2 chrome steel, these offer some of the best smooth speed, especially at this price. Unlike most other companies, the Sonic ABEC 9s have labyrinth seals that prevent dirt and grime from damaging the bearings. Also unique to Sonic is the polymer cage that absorbs vibrations and reduces weight better than traditional brass or steel.
