Seismic Fullspin 6-Ball Steel XT Classic Lagers (set of 8)

THE BASICS 6-Ball system Less total friction, better acceleration and speed on straightaways. Recommended for LDP and top-speed pursuits. Premium Steel balls Truer, lower-friction ball spin inside bearings. Exceptionally tight, consistent assembly and raceway tolerances Significantly less internal play, friction, wear, and noise. Superior speed, handling, and durability. Extra-tough steel and thicker outer rings Raceways hold strictest curvature and finest surface finish and bearings stay tight and fast for far longer. Thicker, 60%-stiffer outer rings resist flexing, spin truer and faster, and keep seals from popping off on extreme impacts. State-of-the-art Classic spacing / alignment system Fullspin spacers precision-machined from premium bearing steel with smarter, stricter dimensional specs have thicker walls that square up against matching extra-wide inner ring surfaces with superior precision and stability. System levels and steadies all working components of seated bearings better than Classic designs from any other brand, to unlock outstanding paired performance. Synergizes with all advanced features in individual bearings to maintain highly consistent wheel contact and grip; support more predictable slide performance; and 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.
