Fast, smooth, and very long lasting, they remain unequaled in their class. Bones Swiss feature the same ultra high performance components used in Bones Swiss Ceramics, except that the balls are polished chromium steel instead of ceramic.
Bones Swiss have earned their fame through decades of proven, dependable, superior performance for the best skaters in the world. No hype, (ABEC-99!) just the best... ask anyone who has been skating for a few years.
Skate Rated™ - Skate Rated bearings are engineered and tested by Bones Wheels to withstand the high impacts of hard landings and the high side loads of turning. These bearings roll faster and last longer than bearings that use the ABEC rating system. To give Skate Rated bearings an ABEC rating would ignore all the improvements Bones has made over the industry standard. Skate Rated bearings are specifically designed for skateboarding, not electric motors.
Swiss - Swiss bearings accelerate faster, roll smoother and last longer than traditional steel bearings.
