Features:
Experience a comprehensive transformation of your bicycle's most critical bearing interfaces with this high-performance hybrid ceramic bearing set. Designed as a direct-fit upgrade, these bearings integrate durable stainless steel races with advanced silicon nitride (Si3N4) ceramic balls to deliver unmatched efficiency, smoothness, and durability at the core of your drivetrain. Elevate multiple contact points simultaneously for a holistic improvement in power transfer and ride quality.
✅ Optimize Crankset Efficiency & Responsiveness
Installed at the bottom bracket, the hybrid ceramic core dramatically reduces rotational friction where the crankset meets the frame. This results in a significantly more direct and lively pedaling connection, minimizing energy loss for quicker acceleration and sustained momentum. Experience a tangible improvement in drivetrain efficiency, translating more of your power into forward motion.
✅ Enable a Smoother, More Efficient Rear Wheel
Precision-fitted within the rear hub, these bearings ensure optimal wheel alignment with exceptionally low rolling resistance. Their advanced construction promotes incredibly smooth and stable rotation, leading to superior power transfer from the drivetrain to the rim. Enjoy enhanced freewheel performance, better speed retention, and reduced energy loss.
✅ Built for All-Weather Durability & Reliability
Constructed from corrosion-resistant stainless steel and protected by high-performance dual-contact rubber seals, these bearings offer superior defense against harsh conditions. They effectively repel water, mud, and abrasive contaminants, ensuring consistent, reliable operation for commuting, adventure riding, and competitive cycling in any environment.
✅ Precision-Engineered for Long-Lasting Performance
Pre-lubricated and manufactured to exacting standards, each sealed bearing unit is engineered for extended service life with minimal maintenance. The wear-resistant ceramic balls and robust construction significantly reduce long-term wear compared to standard bearings, providing a dependable, low-maintenance solution for lasting performance.
Equip your bicycle with the essential upgrades for peak performance. This set delivers measurable gains in responsiveness, durability, and overall efficiency across key drivetrain points, providing the high-performance foundation serious riders demand.
