The Stan’s NoTubes Arch S2 [paid link] wheels are a popular choice for cyclists who seek a balance of strength, lightweight performance, and durability, making them ideal for various types of road cycling. As with any high-performance wheelset, regular maintenance is essential to keep them in top condition, and one of the key aspects of wheel maintenance is truing. Truing ensures that your wheels remain perfectly round and straight, preventing wobbling, enhancing braking efficiency, and improving overall performance.

This guide will walk you through the process of truing your Stan’s NoTubes Arch S2 [paid link] wheels. Whether you’re an experienced rider or a beginner, this detailed step-by-step process will help you achieve a smooth, reliable ride. We’ll cover everything from the tools required to troubleshooting common issues, adjusting spoke tension, and ensuring proper alignment.

Tools Required

To properly true your Arch S2 wheels, you will need the following tools:

  • Spoke wrench (preferably one compatible with the spoke nipples on the Arch S2)
  • Truing stand (or a stationary setup that can hold the wheel in place while you work)
  • 5mm Allen wrench [paid link] (for removing the wheel if necessary)
  • A marker or chalk (for marking spoke nipples and identifying areas needing adjustment)
  • Tension meter (optional but helpful for checking spoke tension)
  • Rim tape (in case the tape needs adjustment or replacement)

Preparing the Wheel for Truing

Before you begin truing your Arch S2 wheels, it’s crucial to ensure the wheel is properly set up and free from any external interference. Follow these steps to prepare your wheel:

1. Remove the Wheel

Start by removing the wheel from your bike. Use a 5mm Allen wrench [paid link] to take out the quick release or through-axle if necessary. Place the wheel on a truing stand or a secure stationary setup that will allow the wheel to rotate freely.

2. Inspect the Wheel for Damage

Before truing the wheel, check it for any visible damage, such as bent rims, cracked spokes, or broken nipples. If you notice any issues that can’t be corrected through truing, consider replacing the damaged parts before proceeding.

3. Clean the Wheel

Clean the wheel thoroughly, especially around the spoke nipples and rim. Dirt and debris can affect the accuracy of your adjustments and may cause wear over time.

Truing Process

With your wheel set up and clean, you’re ready to begin the truing process. This involves adjusting the spoke tension to ensure that the wheel is true (straight and round).

1. Adjust Lateral Truing (Side-to-Side)

Lateral truing refers to correcting any side-to-side wobble in the wheel. To check this, rotate the wheel while it is in the truing stand and observe how the rim behaves in relation to the fixed reference point.

  • If the rim wobbles left or right, identify the sections where the wobble is most pronounced.
  • Using the spoke wrench, tighten or loosen the spoke nipples on the side of the wheel where the rim is displaced.
    • Tighten the spokes on the side that is further from the centerline.
    • Loosen the spokes on the opposite side to reduce tension and bring the rim closer to the center.

Be sure to adjust the spokes gradually and make small, consistent changes to avoid over-tensioning.

2. Adjust Radial Truing (Roundness)

Radial truing ensures the wheel stays evenly round. To check for roundness, rotate the wheel and observe if any section of the rim deviates inward or outward from the wheel’s center.

  • If there’s any noticeable bulge or dip in the rim, adjust the spokes evenly around the wheel.
    • For a bulging area, slightly tighten the spokes in that section.
    • For a recessed area, loosen the spokes to allow the rim to expand outward.

Make sure to rotate the wheel and check the roundness frequently, making small adjustments as needed.

3. Use a Marker for Precision

To help with precision when truing your Arch S2 wheel, mark the spoke nipples with a small chalk or marker. This allows you to easily identify the areas that need adjustment and track progress over time.

Checking and Adjusting Spoke Tension

Proper spoke tension is critical for wheel longevity and performance. An even spoke tension will help the Arch S2 maintain its true form under pressure. Use a spoke tension meter for the most accurate results.

  • Start by checking the tension of each spoke. Spokes that are too loose or too tight can cause the wheel to go out of true faster.
  • Adjust spoke tension across the entire wheel to ensure consistency. Typically, the spokes on the drive side will have a slightly higher tension than those on the non-drive side, but the tension should be balanced around the wheel.

Troubleshooting Common Set-Up Issues

1. Wheel Wobbling After Truing

If your wheel still wobbles after truing, the issue could be uneven spoke tension. Check all spoke tensions again and make small adjustments to ensure they are consistent across the entire wheel.

2. The Rim Is Not Staying True

If the rim continues to shift despite adjustments, there could be an issue with the spoke nipples or the rim itself. Check for any loose or damaged nipples and replace them as necessary. Additionally, ensure the rim is properly seated on the hub and that no parts are misaligned.

3. Uneven Brake Pad Contact

If the brake pads are not making even contact with the rim after truing, ensure that the wheel is properly centered in the brake calipers. Adjust the calipers or spacers if needed to align them with the rim.

Customizing and Optimizing Your Arch S2 Wheels

Once your Arch S2 wheels are true and tensioned correctly, you may want to optimize them for better performance, depending on your riding style.

  • Wheel Alignment for Aerodynamics: If you are using the wheels for competitive cycling, aligning the spoke tension for optimal aerodynamics can improve speed. This involves slightly altering the spoke tension on the non-drive side to make the wheel more stable at high speeds.
  • Tubeless Set-Up: The Arch S2 wheels are tubeless-ready. If you have not already set up your wheels with tubeless tires, this can help reduce the risk of punctures and improve ride quality. Ensure that the rims are properly sealed, and follow the recommended guidelines for tubeless setup.

Comparison with Other Models

The Stan’s NoTubes Arch S2 wheels are known for their strength, light weight, and durability. When compared to other wheels in their class, such as the Zipp 303 Firecrest or Mavic Ksyrium Pro, the Arch S2 offers superior rim strength without sacrificing weight. While the Zipp wheels may offer more aerodynamics, the Arch S2 is an excellent choice for road cyclists who prioritize a combination of durability and weight savings. When comparing performance, the Arch S2 is well-suited for cyclists looking for versatility across different terrains and conditions.

Compatibility with Other Drivetrain Components

The Stan’s NoTubes Arch S2 wheels are compatible with most modern drivetrains, including both Shimano and SRAM systems. The wheels come with a range of freehub options, including Shimano HG and SRAM XD, so you can easily pair them with your existing cassette. However, be sure to double-check your cassette’s freehub compatibility before installing it to avoid any issues during installation. Additionally, the Arch S2 is compatible with both disc brakes and rim brakes, making it a versatile [paid link] choice for a variety of bike setups.

By following these steps, your Stan’s NoTubes Arch S2 wheels will stay true and perform at their best, ensuring a smooth and efficient ride for miles to come. Regular truing and proper maintenance will help maximize the lifespan of your wheels and improve your cycling experience.
