The SUPER BADDEST ABEC7 is a combination of NINJA’s high performance bearing “Raijin” and the highest quality oil “NINJA SUPER BADDEST OIL”. The structure of the bearing is designed to have a larger radial schema (gap between the pawl that supports the ball) and to rotate faster than NINJA’s regular “Raijin ABEC7” NINJA ABEC7. The larger radial schema also reduces the load on the ball due to thermal expansion. This bearing is optimized for skateboarding. NINJA SUPER BADDEST OIL, NINJA’s highest grade oil, is used. The oil is a pure Japanese chemical synthetic oil made to have ultra-low viscosity and ultra-low friction but still clings well. Performance: ABEC7 Lubricant: Oil 1 set/8pcs.
