THE BASICS

10MM system – Fits thicker 10mm axles only.

Premium Ceramic balls – Lighter, smoother, harder, lower in friction, self-lubricating, more heat-resistant, completely rustproof. Increased acceleration, speed, and durability versus Steel balls.

Exceptionally tight, consistent assembly and raceway tolerances – Significantly less internal play, friction, wear, and noise. Superior speed, handling, and durability.

Extra-tough steel – Raceways hold strictest curvature and finest surface finish – and bearings stay tight and fast – for far longer.

State-of-the-art Built-In spacing / alignment system – Integral half-spacers with smarter, stricter dimensional specs square up inside wheels with outstanding precision and stability. System levels and steadies all working components of seated bearings to unlock truly exceptional paired performance. Synergizes with all advanced features in individual bearings to maintain extremely consistent wheel contact and grip; support highly predictable slide performance; and noticeably extend both wheel and bearing life.

High-end lubricant – Formulated for peak performance under real-world skating stresses (not max free-spin time).

Labyrinth-style outer seals – Edges of seals slot inside V-shaped grooves for maximum resistance to dust and debris.

Next-level anti-contaminant ball retainers – Expanded outer diameter slots into groove in outer ring just like a second seal, to form a unique integral barrier against dirt and grime.
