The Campagnolo Bora One 35 [paid link] wheelset is a high-performance carbon road wheelset designed for cyclists seeking a balance of aerodynamics, weight savings, and stiffness. With a 35mm carbon rim, USB ceramic bearings, and 2-Way Fit tubeless compatibility, these wheels deliver speed and reliability. Proper installation and maintenance are key to maximizing performance and longevity.

This guide provides detailed instructions on installing, adjusting, and maintaining the Bora One 35 [paid link] wheelset, ensuring a smooth ride and long-lasting performance.

Tools Required

To properly install and maintain the Bora One 35 [paid link] wheelset, you’ll need the following tools:

  • Torque wrench [paid link] (for hub and cassette installation)
  • Cassette lockring tool [paid link]
  • Chain whip
  • Tire levers
  • Tubeless valve core remover (if using tubeless)
  • Track pump with pressure gauge
  • Spoke tension meter (for wheel truing)
  • Clean rags and isopropyl alcohol (for cleaning braking surfaces)

Installing the Bora One 35 Wheelset

1. Preparing the Frame and Fork

Before installing your Bora One [paid link] 35 wheels, inspect your bike’s dropouts and thru-axles (or quick-release skewer if applicable) to ensure they are clean and free of debris. This prevents improper alignment or slippage.

2. Installing the Cassette

  1. Place the freehub body on a flat surface and check for wear.
  2. Apply a small amount of grease to the cassette splines.
  3. Slide the cassette sprockets onto the freehub, ensuring proper order.
  4. Secure with the lockring, using a cassette lockring tool [paid link] and a torque wrench [paid link]. Torque to 40Nm.

3. Mounting the Tires

The Bora One [paid link] 35 supports both clincher and tubeless tires (2-Way Fit model). Follow these steps:

Clincher Setup:

  • Insert an inner tube into the tire.
  • Mount one side of the tire onto the rim, then carefully tuck the tube inside.
  • Finish seating the tire onto the rim.

Tubeless Setup:

  • Insert a tubeless valve and tighten the lockring.
  • Mount the tubeless tire onto the rim.
  • Use a tubeless inflator or high-pressure pump to seat the tire.
  • Add the recommended amount of sealant through the valve core.

4. Installing the Wheels on the Bike

  1. Align the Bora One [paid link] 35 wheelset into the fork and frame dropouts.
  2. Insert the thru-axle (or quick-release skewer) and secure it. Torque to 12-15Nm for thru-axles.
  3. Spin the wheel to check for proper alignment and clearance.

Adjusting the Bora One 35 Wheelset

1. Setting the Correct Tire Pressure

Tire pressure affects rolling resistance, grip, and comfort. Recommended pressures:

  • Clincher tires: 90-110 PSI
  • Tubeless tires: 75-100 PSI

Adjust based on rider weight and road conditions.

2. Hub Bearing Adjustment

The USB ceramic bearings in the Bora One 35 wheels require precise adjustment:

  1. Check for play in the hub by rocking the wheel side to side.
  2. If there is movement, use a cone wrench [paid link] to adjust the preload.
  3. Tighten until the wheel spins smoothly but without lateral movement.

3. Truing the Wheels

If your wheels develop a slight wobble, use a spoke tension meter to check tension:

  • Identify loose or excessively tight spokes.
  • Turn spoke nipples in ¼-turn increments to adjust lateral trueness.
  • Keep the rim centered within the brake calipers.

Maintaining the Bora One 35 Wheelset

1. Cleaning the Carbon Braking Surface

For rim brake versions, the carbon brake track must be clean for optimal braking:

  • Use isopropyl alcohol and a clean rag to wipe the braking surface.
  • Avoid using oil-based cleaners.

For disc brake versions, clean the rotors with isopropyl alcohol and a lint-free cloth.

2. Hub and Freehub Maintenance

  1. Remove the rear wheel and pull the freehub body off the axle.
  2. Clean old grease and inspect the pawls for wear.
  3. Apply a small amount of light freehub grease before reinstalling.

3. Checking Spoke Tension

Spokes should have even tension for durability. Check every 3-6 months and adjust as necessary.

4. Bearing Lubrication

Although the USB ceramic bearings are low-maintenance, cleaning and relubricating them yearly helps prevent contamination and wear.

Common Issues and Troubleshooting

1. Noisy Freehub

  • Solution: Clean and relubricate the freehub mechanism.
  • Use light grease on the ratchets but avoid over-applying.

2. Braking Issues on Rim Brake Versions

  • If braking feels weak or uneven, clean the carbon brake track.
  • Check if the brake pads are aligned properly with the rim.

3. Spoke Loosening

  • If you hear creaking noises, check for loose spokes.
  • Retighten using a spoke wrench to the correct tension.
