3. Setup and Installation
Proper installation is crucial for the safety and performance of your wheelset. If you are unsure about any steps, please consult a professional bicycle mechanic.
3.1 Cassette Installation
The BUCKLOS wheelset is compatible with 8, 9, 10, and 11-speed cassettes. A cassette is not included with the wheelset and must be purchased separately. Follow the manufacturer's instructions for your specific cassette model. Ensure the cassette is securely fastened to the freehub body.
3.2 Disc Brake Rotor Installation (for Disc Brake Models)
If your bicycle uses disc brakes, you will need to install a compatible disc brake rotor onto the hub. The BUCKLOS wheelset is compatible with six-hole disc brake rotors. Rotors are not included with the wheelset.

3.3 Tire Installation
The rims are designed for 18-25c clincher tires and Presta valves. Install your chosen tires and inner tubes according to their respective manufacturer's guidelines. Ensure the tire bead is properly seated on the rim and inflate to the recommended pressure.
3.4 Wheel Installation onto Bicycle
The wheelset includes quick release skewers for easy installation. The front axle spacing is 9x100 mm and the rear axle spacing is 10x135 mm. Securely mount the wheels onto your bicycle's frame and fork using the quick release levers. Ensure the quick release levers are tightened correctly to prevent wheel detachment during riding.
4. Operating Instructions
Once installed, your BUCKLOS wheelset is ready for use. Always perform a pre-ride safety check to ensure all components are secure and functioning correctly.
4.1 Brake System Check
Verify that your brake system (either disc or rim brake) engages properly and provides adequate stopping power. Adjust brake calipers or pads as necessary to ensure proper alignment and function with the wheelset.
4.2 Tire Pressure
Maintain appropriate tire pressure as recommended by your tire manufacturer. Correct tire pressure is essential for ride comfort, performance, and puncture resistance.
4.3 Riding Conditions
This wheelset is suitable for various road conditions, including racing, rough roads, and different weather conditions. However, always ride within your skill level and adhere to local traffic laws and safety guidelines.

5. Maintenance
Regular maintenance will extend the lifespan of your BUCKLOS wheelset and ensure safe operation.
5.1 Cleaning
Clean your wheels regularly with mild soap and water. Avoid harsh chemicals or high-pressure washers, which can damage bearings and finishes. Pay attention to the braking surfaces (rim or rotor) to ensure they are free of dirt and grime.
5.2 Spoke Tension
Periodically check spoke tension. Loose spokes can lead to wheel instability and damage. If you notice any loose spokes or if the wheel appears out of true, have it inspected and adjusted by a qualified mechanic.
5.3 Bearing Inspection
Listen for any unusual noises from the hubs, which could indicate worn bearings. While the hubs feature sealed bearings for durability, extreme conditions or prolonged use may require professional inspection and servicing.
5.4 Rim Tape
Ensure the rim tape (tire pad) between the rim and inner tube is properly positioned and in good condition. A damaged or improperly seated rim tape can lead to pinch flats. Replace if necessary.
6. Troubleshooting
This section addresses common issues you might encounter with your wheelset.
6.1 Frequent Flats
- Cause: Improper tire pressure, sharp objects embedded in the tire, or faulty rim tape.
- Solution: Check tire pressure before each ride. Inspect tires for embedded debris. Ensure rim tape is securely covering all spoke holes.
6.2 Wheel Wobble or Untrue Wheel
- Cause: Loose or unevenly tensioned spokes, or impact damage.
- Solution: A slight wobble can often be corrected by adjusting spoke tension. For significant wobbles or after an impact, professional truing by a bike mechanic is recommended.
6.3 Noisy Hubs
- Cause: Contaminated or worn bearings, or issues with the freehub body.
- Solution: Inspect the hubs for dirt or damage. If the noise persists, professional servicing of the bearings or freehub is advised.
