The Sonic SuperSonic ABEC 7 Skate Bearings are built using high-precision, heat treated balls and races that are made of some the highest quality 52100 chrome steel. To lighten the bearing and to dampen vibration, Sonic used a polymer cage rather than brass or steel. The stepped inner races and non-contact rubber seals do an excellent job keeping the bearing clean without slowing the skater down.
