The Zipp 404 NSW [paid link] is a high-performance carbon wheelset known for its aerodynamic efficiency, lightweight construction, and superior handling. Whether you’re upgrading your road bike or maintaining your existing set, proper installation, adjustment, and regular upkeep are essential to maximize the wheels’ potential.

This guide will take you through the installation, adjustment, and maintenance of the Zipp 404 NSW [paid link] wheelset, covering essential tips for ensuring optimal performance and troubleshooting common issues.

Tools Required

Before starting the installation, gather the following tools:

  • Torque wrench [paid link] (for securing the cassette and thru-axles)
  • Cassette lockring tool [paid link] (for installing the cassette)
  • Tubeless tire levers (if using a tubeless setup)
  • Tubeless valve core remover
  • High-pressure floor pump or CO₂ inflator
  • Disc rotor lockring tool [paid link] (for disc brake models)
  • Spoke tension meter (for checking spoke tension)

Installing the Zipp 404 NSW Wheelset

1. Preparing the Wheelset

Before installation, inspect the wheels for any factory defects or damage during shipping. Ensure the hubs spin smoothly and check for any loose spokes.

2. Mounting the Cassette

  1. Select a compatible Shimano, SRAM, or Campagnolo cassette based on your drivetrain.
  2. Slide the cassette onto the freehub body, ensuring each sprocket aligns correctly.
  3. Use a cassette lockring tool [paid link] to tighten the lockring to the manufacturer’s specified torque (typically 40 Nm).

3. Installing the Tires

  • For clincher tires: Insert the inner tube, ensuring the valve is aligned properly. Carefully seat the tire bead into the rim.
  • For tubeless tires: Install a compatible tubeless valve, pour the recommended amount of sealant, and inflate using a high-pressure pump. Ensure the tire beads properly onto the rim.

4. Attaching the Wheels to the Bike

  • For quick-release axles: Slide the wheel into the dropouts, ensuring proper alignment. Tighten the quick-release lever securely but avoid overtightening.
  • For thru-axles: Insert the axle through the dropouts and wheel hub, then tighten to the recommended torque.

5. Installing Disc Rotors (If Applicable)

If using the disc brake version of the Zipp 404 NSW [paid link]:

  • Align the rotor with the hub mounting points.
  • Secure using a lockring tool [paid link] and tighten to 40 Nm.
  • Check for rotor alignment to avoid brake rub.

Adjusting the Zipp 404 NSW Wheelset for Optimal Performance

1. Checking Wheel Trueness

Spin the wheels to ensure they are true. If slight wobbling is present, a professional wheel truing session may be needed.

2. Optimizing Tire Pressure

  • For tubeless setups: Maintain 70–90 PSI for road applications.
  • For clincher setups: Follow tire manufacturer recommendations but typically within 85–100 PSI.

3. Ensuring Proper Hub Adjustment

The Zipp Cognition hubs are factory-adjusted but should be checked periodically. Ensure there is no side-to-side play by gently rocking the wheel at the axle.

4. Aligning Brakes for Maximum Efficiency

  • For rim brakes: Ensure the brake pads contact the braking surface evenly.
  • For disc brakes: Adjust caliper alignment if you hear rotor rubbing.

Maintaining Your Zipp 404 NSW Wheelset

1. Cleaning the Wheelset

Regular cleaning prevents contamination and extends lifespan. Use a mild detergent and soft brush to clean the carbon rims. Avoid high-pressure water jets that may force dirt into the bearings.

2. Checking and Retensioning Spokes

Every 1,000 miles, check spoke tension using a spoke tension meter. Loose or uneven spokes should be addressed immediately to prevent premature wear.

3. Inspecting Bearings and Hubs

  • Annually, remove the hub bearings for inspection.
  • If bearings feel rough or gritty, replace them with high-quality ceramic or steel options.

4. Ensuring Tubeless Sealant is Fresh

  • Every 3–6 months, check and replenish sealant to avoid puncture issues.

5. Monitoring Brake Track Wear (For Rim Brake Models)

Riders using rim brakes should check the brake track for excessive wear. A textured braking surface fading means it’s time to replace the wheel or switch to disc brakes.

Troubleshooting Common Issues with the Zipp 404 NSW Wheelset

1. Wheel Feels Sluggish or Slow

  • Check hub bearings for wear.
  • Ensure proper tire pressure for rolling efficiency.

2. Braking is Noisy or Inconsistent

  • For rim brakes, clean the braking surface with alcohol.
  • For disc brakes, check for contamination and realign the rotor.

3. Spokes Keep Coming Loose

  • If spokes frequently loosen, consult a professional wheel builder for tension adjustments.

4. Wheel Wobbles or is Out of True

  • Minor adjustments can be made using a spoke wrench, but major truing should be left to a pro.

Final Thoughts

The Zipp 404 [paid link] NSW wheelset is designed for speed and durability, but proper installation, adjustment, and maintenance are key to maximizing performance. By following this guide, you’ll ensure your wheels stay in top condition for years to come.
