ONI Bearing ROAD BIKE



ONI BEARING Performance

Highly rated for their supreme low-torque performance, these
bearings are used on the race bikes of MATRIX POWERTAG, one of
Japan's leading road bike racing teams.

Well-received by riders of this team, ONI BEARINGS have been
praised as being “incomparably lighter” and “especially nimble when
coming out of corners,” and are expected to make further
contributions to the team's performance this season.

SMOOTHESTRolling Resistance In The Industry

ONI BEARINGS are recommended for long rides, as they provide about six times longer continuous wheel rotation than wheel manufacturer original bearings. They also provide smooth rolling resistance that ensures stability when coming out of corners and during riding.

LOWESTTorque In The Industry

ONI BEARINGS have achieved the lightest pedaling in the industry because they feature significantly lower torque than wheel manufacturer original bearings.

AMAZINGDurability!

Rotational performance that remains unchanged in endurance tests equivalent to 100,000 km of use

<Test Results>
<Test Conditions>
  • Bearing: 6903 (17×30×7)
  • Load: 500 N (twice the anticipated load during riding)
  • Rotational speed: 600r/min-1(equivalent to 80 km/h)

We conducted stand-alone endurance tests on ONI BEARINGS.
After 1250 Hours (approx.100,000 km) ride, ONI BEARINGS kept the same rotational performance without abrasion. It kept the same performance as the new one.
*We do not guarantee for the 100,000 km ride.

Even without maintenance, performance remained the same after one season of use by a professional rider

<Test Conditions>
  • Tested bearings: ONI BEARINGS used for one season in 2022 by five professional riders

We provided ONI BEARINGS to the MATRIX POWERTAG professional riding team, after which we disassembled the ONI BEARINGS after being used for one season to investigate their state of wear and other conditions. Despite a grueling race for one season, it kept the same performance as the new one.

SIGNIFICANT TIME REDUCTION!Effective Even On Hill Climbs!!

We conducted time comparisons by having professional riders perform road tests using both
the wheel manufacturer's original bearings and ONI BEARINGS.
Tests were performed using the same measurement conditions for both bearings.

<Measuring Method>

Power was measured with power pedals, while other data was collected using a bike computer.
Time comparisons were performed twice—both with and without ONI BEARINGS.

<Measurement Conditions>
  • Test rider: Professional rider from MATRIX POWERTAG (62.8 kg)
  • Bicycle: Time Alpe d'Huez 01 (7.8 kg)
  • Wheels: Mavic Cosmic SLR 32
  • Tires: Continental Grand Prix 4000S25C
  • Tubes: TIOGA; Air pressure: 4.5 bar
  • Brakes: Disc; Front 160 mm, Rear 140 mm
  • Power pedals: Wahoo POWRLINK ZERO (dual-sided pedals)
  • Bike computer: Wahoo ELEMNT ROAM (WFCC4)
  • Riding conditions: Sustained riding at 290 W (watts)
  • Measurement distance: 3.8 km × 4 times (with ONI BEARINGS × 2 times, wheel manufacturer original bearings × 2 times)

Frequently Asked Questions for ONI Bearing ROAD BIKE

What is ONI Bearing?
ONI Bearing is a Premium High-Performance, Ultra-Low torque ceramic ball bearing developed by (KOYO) JTEKT Corporation specialized for road bicycles.
ONI Bearing used primarily by professional road cycling teams like Team Visma I Lease a BIke (TVL) a top-tier UCI World Team and Japan's MATRIX POWERTAG a leading Japanese road bicycle racing team.
- Material: Cermaic Ball

- Performance: Significantly lower friction and higher durability

- Impact: Approximately 6 x longer continuous rotation than normal road bike bearings.
1. Offer up to 6 times Longer.

2. Smoother Rotation than Stock Bearings.

3. Enabling Easier Pedaling.

4. Better Speed Maintenance.

5. Used by pro teams like Team Visma I Lease a bike, they are designed for maximum efficiency.
1. Advance Lubrication Method (Non-Churning) -  Unlike conventional bearings that pack grease directly onto the rolling parts, causing high churning resistance. ONI Bearing seal the grease in a seperate location. Only the oil component of the grease travels to the balls and rings tolubricate them, which prevents the buildup of old grease that normally requires cleaning.

2. High-Durability Ceramic Components - The Bearing balls are made of low-density, high - corrosion and wear - resistant ceramic. These materials are designed to operate effectively with minimal lubrication without experiencing significant seizure or wear even over long distances.

3. "Sealed for life" design - The bearing use specialized sealing that prevents external contaminants like water, dust and mud from entering, while preventing the internal lubrication from escaping.

4. Corrosion-Resistant Materials - The inner and outer rings are made of high-grade stainless steel (SUS 440C), Which prevents rust caused by rain or sweat, a common reason for needing to replace or service standard bearing.

5. Extensive Durability Testing - Tests have shown that ONI Bearing maintain their rotational performance for over 100,000 km, reducing the need to replace or mainteain them for a significant period.
 Performance Benefits

  • Reduced Rolling Resistance: Provides approximately six times longer continuous wheel rotation compared to standard manufacturer bearings.

  • Energy Efficiency: Drastically reduces internal torque, ensuring more of the rider's power is converted directly into speed.

  • Superior Durability: Engineered for a long lifespan, with tests showing zero performance degradation even after 100,000 km of use.

  • Smooth Handling: Enhances stability during riding and especially when exiting corners.

  • Corrosion Resistance: Uses stainless steel for inner and outer rings, preventing torque increases caused by rain or sweat.



  • Precision Alignment: JTEKT recommends using a specific installation jig that fits the bearing perfectly to ensure it is pressed in completely flat without play.

  • Required Tools: You will need a bearing press with the correct sized drifts for your specific bearing model (e.g., 6903). Using a hammer is strongly discouraged as it can crack the ceramic balls or mar the races.

  • Technique: Pressure must be applied only to the outer race when pressing into a hub shell, or the inner race when pressing onto an axle. Never apply force through the rolling elements.

  • Authorized Bike Shop: Stronly recommended to visit, consult and install by the well trained technician by us.
