Truing your wheels is an essential part of maintaining your bike, ensuring that your Next SL 29 [paid link] wheels perform at their best. This guide will walk you through the process of truing your wheels, offering tips for adjustments, troubleshooting common issues, and optimizing your setup. By following these steps, you’ll be able to achieve a smooth, reliable ride with your Race Face Next SL 29 [paid link] wheels.

Tools Required

Before beginning, make sure you have the following tools at your disposal:

  • Wheel truing stand
  • Spoke wrench (appropriate size for your spokes)
  • Dishing tool (optional, for checking wheel dish)
  • Caliper or ruler (for measuring spoke tension)
  • Bike stand [paid link] (for easy access and secure positioning)
  • Lubricant (for spoke nipples)

Understanding the Next SL 29 Wheels

The Race Face Next SL 29 wheels are designed for high-performance mountain biking, offering a lightweight yet durable setup. These wheels feature carbon fiber rims, which provide a balance of strength and responsiveness. As with any high-end component, regular maintenance, such as wheel truing, is crucial to keep the wheels functioning at their peak [paid link].

Why Wheel Truing is Important

Truing ensures that your wheels remain straight and spin without wobble. This process helps to:

  • Prevent tire wear caused by uneven contact with the ground.
  • Reduce unnecessary strain on your hub and spokes.
  • Improve braking performance and stability, especially at high speeds.
  • Prolong the life of your rims and spokes by keeping them properly aligned.

Step-by-Step Guide to Truing Your Next SL 29 Wheels

1. Secure the Wheel in a Truing Stand

  • Mount your Next SL 29 wheel in a truing stand. The stand should be stable, allowing the wheel to spin freely without any wobbling or interference. Ensure the wheel is centered on the stand, so you can accurately assess the truing process.

2. Inspect the Wheel for Wobble

  • Spin the wheel slowly and observe the rim. Look for any side-to-side movement (lateral wobble) or up-and-down movement (radial wobble). These are the two main issues that need addressing during truing.
  • For lateral wobble, the rim will shift side to side when spinning. For radial wobble, the rim will appear to move vertically, which often means the wheel is not perfectly round.

3. Tighten or Loosen Spokes for Lateral Truing

  • Use your spoke wrench to adjust spoke tension. Start with the high spots on the rim (the areas that cause wobble), and adjust the spokes on those sections.
  • To correct a lateral wobble, tighten the spokes on the side of the wheel where the rim is closest to the truing stand. This will pull the rim away from the stand, reducing the wobble.
  • Conversely, loosen the spokes on the opposite side of the wheel to allow the rim to move closer to the truing stand, thereby correcting the wobble.

4. Correct Radial Wobble

  • If you notice a radial wobble (vertical movement), inspect the spokes in the affected area. A spoke that is too tight or too loose can cause the wheel to be out of round.
  • Loosen spokes that are pulling too tightly, and tighten those that are too loose. Make small adjustments to avoid over-correcting, as this can cause further issues.

5. Check for Proper Spoke Tension

  • It’s important to maintain even spoke tension across the entire wheel. Uneven tension can lead to long-term issues with wheel integrity. Use a caliper or ruler to measure the spoke tension and adjust where necessary.
  • Spoke tension should be fairly consistent, with no single spoke feeling much tighter than the others. If you notice large variations, it may be time to replace some spokes or adjust their tension more thoroughly.

6. Inspect for Dishing

  • The dishing of your wheel refers to how evenly it sits in the center of the hub. Use a dishing tool to check the alignment of the rim with the hub. If the wheel is not properly centered, it may affect performance and handling.
  • Adjust the spoke tension on one side of the wheel to correct the dishing. Make sure the wheel remains centered in both lateral and radial directions as you go.

7. Final Checks and Re-Tensioning

  • After making adjustments, spin the wheel again to check for wobble. Repeat the process of tightening or loosening spokes until the wheel is true both laterally and radially.
  • Once you’re satisfied with the truing, check that all spokes have even tension. Re-tension the spokes as necessary to ensure consistency across the wheel.

Troubleshooting Common Issues

Uneven Spoke Tension

  • If one side of the wheel remains too tight while the other side is loose, it can result in a poorly balanced wheel. Ensure you’re adjusting spokes gradually and in small increments, checking tension often.

Rim Contact with Brake Pads

  • If your rim continues to wobble despite truing, check for other issues such as a worn-out or bent brake rotor. A bent rotor can cause the rim to shift slightly when braking, even if the wheel is otherwise true.

Persistent Radial Wobble

  • A radial wobble that doesn’t seem to resolve may indicate that your wheel has suffered damage, such as a cracked rim or a spoke that is broken but still under tension. Inspect all spokes carefully and replace any that show signs of damage.

Optimizing Your Next SL 29 Wheels

Adjusting for Performance

  • For racers or performance-oriented riders, maintaining your Next SL 29 wheels in optimal condition is critical. Consider using higher-quality spoke nipples and lubricant for smoother spoke movement and to prevent corrosion. Also, ensure that the spoke tension is at the higher end of the recommended range to improve the stiffness of the wheel.

Customization for Ride Style

  • Depending on your riding style, you may want to adjust spoke tension slightly for more compliance or stiffness. Lighter riders may find a slightly lower spoke tension comfortable for absorbing impacts, while heavier riders may benefit from higher tension for better support during hard riding.

Compatibility with Other Drivetrain Components

When working on your wheels, it’s essential to ensure compatibility with other drivetrain components. The Next SL 29 wheels are designed to work seamlessly with modern 1x and 2x drivetrains. However, you should verify the following before installation:

  • Hub Compatibility: Ensure the hub on your Next SL 29 wheels is compatible with your bike’s cassette and freehub system. The wheels are compatible with both Shimano and SRAM cassettes, but verify the freehub body type before installation.
  • Brake Compatibility: The wheels are available in both disc brake and rim brake versions. Be sure that your bike’s brake system matches the type of rim (or rotor mount) on your Next SL 29 wheels.

Conclusion

Truing your Next SL 29 wheels is a straightforward process with the right tools and techniques. By regularly checking for lateral and radial wobble, adjusting spoke tension, and ensuring proper wheel dishing, you can keep your wheels running smoothly for a long time. By following the steps outlined in this guide, you’ll be able to address common wheel issues, improve performance, and enhance the overall durability of your Race Face Next SL 29 wheels. Regular maintenance will ensure your ride is always smooth, safe, and enjoyable.
