PERFORMANCE SPECS

  • Smoothest Ceramic Bearings

    Engineered for the Long Haul

    ONI Bearings aren't just an upgrade; they are a transformation. ONI ceramic bearings deliver approximately six times longer continuous wheel rotation compared to standard manufacturer bearings.

  • Lowest Torque Ceramic Bearings

    Lightest Feel

    Unlock the lightest pedal stroke in cycling. ONI Bearings drastically reduce internal torque compared to even the most popular bearings brands in the industry, ensuring every watt goes directly into your speed.

  • Graph showing ONI Bearings maintain rotational performance over 100,000 km of use

    Engineered to Last: Zero Degradation Over 100,000 km

    Stand-alone endurance tests confirm that ONI Bearings retain their peak rotational performance even after 1,250 hours (approx. 100,000 km) of use. Our testing showed no signs of internal abrasion, with aged bearings performing identically to factory-new units.

    Disclaimer: While these test results highlight exceptional durability, 100,000 km is not a guaranteed service life for all riding conditions.

    Post-Race Analysis: Zero Performance Degradation

    Following a full season of elite-level racing, ONI Bearings were recovered and analyzed to evaluate internal wear patterns. Our investigation confirmed that even after a year of high-torque competition and environmental exposure, the bearings exhibited zero measurable abrasion. Performance metrics remained identical to brand-new units, confirming ONI's superior longevity.
