Features:
Upgrade your bicycle's critical rotation points with this direct-fit hybrid ceramic bearing kit. It combines durable, high-carbon chromium steel (GCr15) races with precision silicon nitride (Si₃N₄) ceramic balls. This hybrid approach delivers the resilience of steel alongside the friction-reducing benefits of advanced ceramics. Produced to ABEC-9 standards and shielded by high-grade, double-contact rubber seals (2RS), these bearings enhance efficiency and durability where your bike needs it most.
✅ Direct & Efficient Bottom Bracket Performance
Once fitted to your bottom bracket, these bearings significantly reduce rotational drag at the crankset. The ultra-smooth Si₃N₄ ceramic balls minimize energy loss from micro-vibrations, yielding a more immediate and solid pedal feel. This results in crisper power delivery during efforts like sprints, while the sturdy steel races manage everyday road shocks.
✅ Freer, Sustained Wheel Rotation
Installed in your hubs, these bearings promote low-friction, true rotation. The lighter ceramic balls decrease rotational mass for improved acceleration and speed retention. Effective 2RS seals guard against dirt and moisture, maintaining smooth performance on varied surfaces. This means a more lively wheel feel and efficient power transfer to the road.
✅ Dependable in All Conditions
The high-performance 2RS seals actively repel water, grit, and road contaminants—key for longevity where standard bearings suffer. Corrosion-resistant materials ensure consistent function in wet, muddy, or dusty conditions. This design prioritizes real-world sealing reliability for lasting performance.
✅ Engineered for Lasting Value
Pre-greased and built to precise tolerances, these hybrid bearings better resist wear, pitting, and contamination than standard steel bearings. While periodic maintenance is still needed, their robust design extends service intervals, especially in adverse conditions, offering a smart investment in reduced upkeep and sustained ride quality.
Opt for this hybrid bearing set for a tangible upgrade: a more responsive drivetrain, smoother-rolling wheels, and reliable all-weather operation. When properly installed, it elevates your bike's core performance through thoughtful engineering, proving that true value lies in enhanced efficiency and durability for the long ride.
