Sonic ABEC7 Skate Bearings are built using high-precision, heat treated balls and races that are made of some the highest quality Japanese SUJ2 chrome steel. To lighten the bearing and to dampen vibration, Sonic uses a polymer cage rather than brass or steel. The labyrinth seals do an excellent job keeping the bearing clean without slowing the skater down.
