Cema 6805-2RS ABEC5 Hybrid Ceramic Bottom Bracket Bearing 25x37x7 mm

The Cema 6805-2RS ABEC5 Hybrid Ceramic Bottom Bracket Bearing 25x37x7mm is engineered to maximize drivetrain efficiency and deliver ultra-smooth rotation. Ideal for performance-oriented cyclists, it reduces friction and improves power transfer for a faster, more responsive ride.

Optimized for Bottom Bracket Systems: Specifically designed for bottom bracket applications, this bearing ensures precise alignment and minimal resistance. It enhances drivetrain smoothness and consistency, making every pedal stroke feel lighter and more efficient.

Hybrid Ceramic Construction for Superior Performance: Built with high-precision silicon nitride ceramic balls and durable steel races, this hybrid design offers the best of both worlds—lightweight efficiency with exceptional strength. The result is reduced rolling resistance, increased corrosion resistance and extended bearing life.

Double-Sealed for Long-Lasting Protection: Featuring 2RS double seals, the bearing is fully protected from water, dust and contaminants. The seals keep lubrication intact, ensuring consistent smoothness and durability, making it a reliable upgrade for both professional and recreational riders.

Manufactured to ABEC5 standards, the bearing meets strict tolerance requirements for high rotational accuracy. This ensures smooth, quiet operation and excellent stability even under heavy pedaling loads.
