Tools Required

  • Torque wrench[paid link]
  • Cassette lockring tool[paid link]
  • Bottom bracket wrench (for centerlock disc rotor installation)
  • 5mm & 6mm hex keys
  • Spoke tension meter
  • Tubeless tire setup kit (if applicable)
  • Chain whip & cassette removal tool
  • High-quality bike grease

Step-by-Step Installation of the Bora WTO 45 Wheelset

1. Preparing the Wheelset

Before installation, inspect the wheels for any factory defects. Ensure the spoke tension and bearings are correctly set. If running tubeless, install the tubeless rim tape and valves.

2. Installing the Cassette

  • Place the cassette onto the freehub body, ensuring the largest sprocket sits flush.
  • Use a cassette lockring tool[paid link] to tighten the lockring to the manufacturer’s torque specification (typically 40Nm).

3. Mounting the Tires

  • If using clincher tires, insert the inner tube and carefully fit the tire onto the rim.
  • If using tubeless tires, ensure the tubeless tape is properly seated. Install the tubeless valve, add sealant, and inflate the tire to seat it.

4. Attaching the Rotors (Disc Brake Version Only)

  • For centerlock rotors, use a bottom bracket wrench to tighten the lockring to 40Nm.
  • For 6-bolt rotors, tighten the bolts in a star pattern to 6Nm.

5. Installing the Wheels on the Bike

  • Align the wheel with the dropouts.
  • Insert the thru-axle or quick-release skewer, ensuring it is securely fastened.
  • If using disc brakes, verify rotor alignment to prevent rubbing.

Adjusting the Bora WTO 45 for Optimal Performance

1. Checking Bearing Play and Preload

  • The USB or CULT ceramic bearings in the Bora WTO 45 require proper preload adjustment.
  • Spin the wheel in your hands and check for play by rocking it side to side.
  • If there’s movement, adjust the preload using a 5mm hex key[paid link] to eliminate excessive play.

2. Aligning the Brakes

  • For rim brake models, ensure the brake pads are aligned with the braking track.
  • For disc brake models, check that the rotor doesn’t rub by fine-tuning the caliper alignment.

3. Truing the Wheels

  • Use a spoke tension meter to check for even spoke tension.
  • If minor wobbles exist, adjust the spoke nipples 1/8 turn at a time to true the wheel.

Routine Maintenance for the Bora WTO 45

1. Cleaning the Wheelset

  • Use a soft brush and mild detergent to clean the rims and spokes.
  • Avoid high-pressure washers, as they can force water into the hubs and damage bearings.

2. Lubricating the Freehub

  • Remove the freehub body and clean it with a degreaser.
  • Apply a thin layer of high-quality grease or oil, ensuring smooth operation.

3. Bearing Inspection and Service

  • If you notice rough spinning or noise, remove and clean the bearings.
  • Campagnolo CULT bearings require minimal lubrication, while USB bearings benefit from a light application of bearing grease.

4. Spoke Tension Checks

  • Check the spoke tension every 3,000-5,000 km to prevent wheel deformation.
  • Uneven tension can lead to unstable handling, requiring truing adjustments.

Troubleshooting Common Bora WTO 45 Issues

1. Wobbling or Poor Stability

  • Check spoke tension using a tension meter.
  • Inspect the hub bearings for roughness.
  • Ensure the thru-axle or quick-release skewer is tightened correctly.

2. Freehub Slipping or Noise

  • Remove the freehub body and check for dirt buildup.
  • Lubricate the ratchet mechanism with a lightweight oil.

3. Brake Rub Issues

  • For disc brakes, re-align the calipers.
  • For rim brakes, check if the pads are evenly positioned on the braking track.

4. Difficulty Mounting Tires

  • Use soapy water on the tire bead to ease installation.
  • If tubeless, ensure the rim tape is properly applied and the valve core is tight.

Customization and Performance Optimization

1. Running Tubeless for Better Speed and Comfort

  • The Bora WTO 45 is tubeless-ready, which reduces rolling resistance.
  • Use a high-TPI tubeless tire and high-quality sealant to enhance puncture resistance.

2. Choosing the Right Tire Width

  • 25mm tires are ideal for aerodynamics, but 28mm provides better comfort and grip.
  • Ensure the tire width matches the frame clearance.

3. Upgrading Bearings for Maximum Speed

  • The Bora WTO 45 comes with USB ceramic bearings, but upgrading to CULT ceramic bearings reduces friction significantly.
