The Campagnolo Bora Ultra WTO 45 [paid link] is a high-performance carbon wheelset designed for serious road cyclists looking for a balance of aerodynamics, lightweight construction, and durability. Proper installation, adjustment, and maintenance are crucial to ensure optimal performance and longevity.

This guide provides step-by-step instructions for installing the Bora Ultra WTO 45 [paid link], adjusting it for optimal rolling efficiency, and maintaining it to prevent wear and tear. By following these guidelines, you can maximize the lifespan and performance of your investment.

Tools Required

  • Torque wrench [paid link] (for proper tightening of quick-release or thru-axle components)
  • Cassette lockring tool [paid link] (for installing the cassette)
  • Tire levers (for mounting tubeless or clincher tires)
  • Floor pump or CO₂ inflator (to set proper tire pressure)
  • Spoke wrench (for minor spoke tension adjustments)
  • Wheel truing stand (for precise truing and alignment)
  • Grease or assembly compound (for hubs and axle threads)

Installation of the Bora Ultra WTO 45 Wheelset

1. Preparing the Frame and Fork

Before installing the wheels, ensure that the dropouts (fork and rear triangle) are clean and free of debris. Any dirt or grit can cause misalignment or unwanted noise when riding.

2. Installing the Cassette

  • Use a cassette lockring tool [paid link] to securely attach the cassette to the rear wheel’s freehub.
  • Tighten to the manufacturer’s recommended torque (usually 40 Nm for Campagnolo cassettes).
  • Ensure that the cassette is properly seated to prevent shifting issues.

3. Mounting the Tires

  • If using tubeless tires, install the tubeless valve first and ensure it is properly tightened.
  • Mount the tire onto the rim, making sure the bead is correctly seated.
  • Inflate the tire using a floor pump or CO₂ inflator to allow the bead to pop into place.
  • If using inner tubes, insert the tube carefully to avoid pinching.

4. Installing the Wheels onto the Bike

  • If using quick-release skewers, insert them through the hub, ensuring they are properly tightened.
  • If using thru-axles, slide them into place and use a torque wrench [paid link] to tighten them according to manufacturer recommendations.
  • Spin the wheels to check for proper alignment within the frame.

Adjusting the Bora Ultra WTO 45 Wheelset for Optimal Performance

1. Checking Hub Bearings and Preload

The Bora Ultra WTO 45 [paid link] features CULT ceramic bearings, which provide ultra-low friction. However, incorrect preload can cause premature wear.

  • Hold the wheel in your hands and spin it. It should rotate smoothly and silently.
  • If there is lateral play, adjust the preload collar on the hub until the play disappears.
  • Avoid over-tightening, as this can reduce bearing lifespan.

2. Ensuring Proper Spoke Tension

  • Check spoke tension using a spoke tension meter.
  • Uneven spoke tension can lead to lateral wobbles or instability during high-speed descents.
  • If necessary, make small adjustments using a spoke wrench, ensuring even tension across all spokes.

3. Aligning the Wheel in the Dropouts

  • Ensure the wheel sits symmetrically in the fork and rear dropouts.
  • If necessary, reinstall the thru-axle or quick-release and check for alignment.
  • Misalignment can lead to uneven braking performance, especially on rim brake models.

Maintenance of the Bora Ultra WTO 45 Wheelset

1. Regular Cleaning and Lubrication

  • Wipe down the rims and hubs after each ride using a microfiber cloth.
  • Avoid using harsh chemicals on the carbon fiber rims.
  • Periodically lubricate the freehub body to maintain smooth operation.

2. Inspecting Rim Brake Tracks (For Rim Brake Versions)

  • Check for wear indicators on the braking surface.
  • If the rim track appears worn down, replace the wheel or consult a professional mechanic.
  • Use Campagnolo-approved brake pads for optimal braking performance.

3. Tubeless Maintenance

  • Check sealant levels every 2-3 months and top up as needed.
  • Inspect the tubeless valves for blockages.
  • If the tire is difficult to seat, check for rim tape wear and replace it if necessary.

4. Checking for Carbon Rim Damage

  • Inspect for hairline cracks or signs of impact damage after crashes or potholes.
  • Carbon wheels are strong but can suffer from hidden damage, affecting safety.

5. Freehub Maintenance

  • Remove and clean the freehub body every 6 months to ensure smooth engagement.
  • Apply light grease to the engagement mechanism without over-lubricating.

Common Installation and Adjustment Issues

1. Noisy or Wobbly Wheelset

  • Solution: Ensure proper spoke tension and check for hub bearing wear.
  • If the wheel wobbles, place it in a truing stand and adjust accordingly.

2. Difficult Tubeless Setup

  • Solution: Make sure the rim tape is properly installed and the tire bead is fully seated.

3. Braking Issues on Rim Brake Models

  • Solution: Ensure brake pads are properly aligned and not worn down.
  • Use only Campagnolo-approved brake pads to prevent excessive wear.

4. Poor Cassette Engagement

  • Solution: Clean and re-grease the freehub body if shifting feels inconsistent.

Conclusion

The Campagnolo Bora Ultra WTO 45 is a top-tier wheelset that delivers aerodynamic efficiency, lightweight performance, and durability. However, proper installation, adjustment, and maintenance are key to unlocking its full potential.

By following this guide, you can ensure that your Bora Ultra WTO 45 wheels remain in peak condition for years to come. Regular maintenance, such as checking spoke tension, cleaning the freehub, and inspecting for wear, will help keep your ride smooth and efficient.
