Features:
Engineered to eliminate the hidden friction that robs you of speed, this set of Hybrid Ceramic Bearings provides the definitive upgrade for the cyclist's most critical rotating interfaces. Designed for both bottom bracket and rear hub service, this pack systematically converts parasitic drag into pure, usable power, delivering a drivetrain that feels electrified—responsive, silent, and seamlessly connected to the road beneath you.
✅ Aerospace-Grade Core for Frictionless Momentum
Each bearing utilizes silicon nitride (Si3N4) ceramic balls within precision-hardened steel races. This hybrid core reduces rolling resistance at the molecular level, allowing your crank and rear wheel to spin with unprecedented freedom. The result is a palpable surge in efficiency, transforming your sustained power output into greater speed with less perceived effort, especially noticeable during threshold efforts and long, steady climbs.
✅ Total Environmental Sealing for Unwavering Consistency
Protected by dual rubber contact seals (2RS), each bearing is shielded from the real-world elements that degrade performance. This robust sealing technology actively blocks water, abrasive dust, and corrosive road salts, ensuring the buttery-smooth, quiet rotation you experience on day one remains perfectly intact through monsoon rains, gritty gravel sectors, and winter training miles.
✅ Extended Durability for Season-Long Performance
The exceptional hardness of ceramic and the corrosion resistance of the bearing components combat the primary causes of wear. This set is engineered to withstand the repeated, high-load impacts of sprinting and climbing far longer than stock bearings, preventing the onset of rough spots, pitting, and the dreaded "crunchy" feel that signals the end of a standard bearing's life.
✅ Holistic Drivetrain Transformation
Installing this complete set creates a synergistic effect, upgrading the entire power path from pedals to rear wheel. By replacing the standard bearings at both ends, you eliminate compliance and drag across the system. This unification delivers a transformative riding sensation: immediate power engagement, a whisper-quiet drivetrain, and a direct, unfiltered connection that makes the bicycle feel like a precise, natural extension of your body.
This is not merely a replacement—it is a recalibration of your bike's fundamental mechanics. It is the upgrade that makes high-end performance feel intuitive and effortless, proving that the greatest gains often come from perfecting the smallest, most essential components.
