Designed for high-performance cycling applications, this ABEC 5 Grade 3 bearing is ideal for hubs and bottom brackets where low friction and corrosion resistance are critical.
Built using Silicon Nitride (Si3N4) ceramic balls paired with precision-ground steel races, the Zero Ceramic range delivers superior speed, reduced rolling resistance, and enhanced longevity compared to standard steel or ceramic hybrid bearings.
- Reduced rolling resistance for increased speed
- Enhanced corrosion resistance
- Improved power transfer efficiency
- Lightweight at just 13g
- Ideal for performance-focused cyclists
- Long service life compared to standard steel bearings
Grade 3 Hybrid Ceramic Performance
Unlike standard hybrid ceramic bearings, the Zero Ceramic series features:
- Grade 3 Silicon Nitride (Si3N4) ceramic balls for ultra-precise roundness
- Mirror-finished, precision-ground steel races
- Black oxide-treated races for improved corrosion resistance
- Near-perfect tolerances for maximum drivetrain efficiency
The result is a low-friction, high-speed bearing ideal for road, gravel, and MTB performance upgrades.
