Sonic Speed 608 are high performance bearings. Each bearings has 1 blue seal and 1 green seal allowing skaters to customize their wheels and cross check wheel rotation. Unlike most brands, Sonic uses labyrinth seals to prevent dirt and debris from getting inside, which greatly extends the life of the bearing. Sonic also uses premium SUJ2 steel from Japan that maintains its high-level of performance at all levels of play. The zero waste packaging doubles as a useful skate parts organizer.
