The DT Swiss EXC 1200 SPLINE [paid link] wheels are an excellent choice for riders seeking high-performance road wheels. They are designed to provide exceptional durability and strength, making them ideal for aggressive riding and long-distance cycling. One of the most important aspects of maintaining these wheels is ensuring they remain true. Wheel truing involves correcting the lateral and radial deviations of the rim to ensure it runs smoothly and efficiently.

In this guide, we will walk you through the step-by-step process of truing your EXC 1200 SPLINE [paid link] wheels, providing detailed instructions on installation, adjustment, and maintenance. We will also cover common issues and how to troubleshoot them, ensuring your wheels continue to perform at their best.

Tools Required

To successfully true your DT Swiss EXC 1200 SPLINE wheels, you will need the following tools:

  • Spoke wrench (compatible with DT Swiss nipples)
  • Truing stand (optional, but highly recommended)
  • Ruler or caliper (for checking rim alignment)
  • Tension meter (optional, for checking spoke tension)
  • Lubricant or anti-seize compound (for spoke threads)

Installation and Initial Setup of the EXC 1200 SPLINE Wheels

Before diving into the truing process, it’s essential to ensure that your EXC 1200 SPLINE wheels are correctly installed on your bike. The installation procedure is straightforward but requires attention to detail for optimal performance.

  1. Install the wheels onto the bike: Secure the wheels into the frame dropouts or thru-axles, making sure they are properly aligned.
  2. Ensure brake rotor alignment: If your EXC 1200 SPLINE wheels are equipped with disc brakes, check that the rotor is correctly installed and aligned with the caliper.
  3. Check tire pressure: Ensure that the tires are inflated to the recommended pressure. Over- or under-inflation can affect the wheel’s true alignment.

Once the wheels are installed, proceed with the truing process. This is crucial if you’ve noticed any wobble, rubbing, or inconsistent braking performance.

Step-by-Step Guide to Truing Your EXC 1200 SPLINE Wheels

Truing involves correcting both lateral and radial misalignments of the wheel. Follow these steps to accurately true your EXC 1200 SPLINE wheels.

1. Prepare Your Truing Stand

While it’s possible to true a wheel without a truing stand, having one makes the process much easier and more precise. Position the wheel on the stand, making sure it’s securely fastened. Spin the wheel slowly and observe any deviations in the rim’s path.

  • Lateral deviations: This occurs when the rim moves side to side.
  • Radial deviations: This happens when the rim moves up and down, causing a hop.

2. Inspect the Wheel for Deviations

Spin the wheel slowly and observe the rim’s movement. Any lateral or radial misalignment needs to be addressed.

  • Lateral misalignment: If the rim wobbles side to side, you’ll need to adjust the spoke tension on the opposite sides of the wheel.
  • Radial misalignment: If the rim bounces up and down, the spoke tension needs to be adjusted to even out the tension across the wheel.

3. Adjusting Lateral Truing

  • Begin by loosening the spoke nipples on the side opposite the deviation. This will relieve tension and allow the rim to move back to the center.
  • Tighten the spoke nipples on the side of the deviation, gradually pulling the rim toward the center.
  • Repeat this process, checking the wheel regularly to ensure it’s becoming more centered.
  • Work in small increments and make fine adjustments, as overtightening spokes can cause further misalignment.

4. Adjusting Radial Truing

Radial truing focuses on eliminating any hop or vertical wobble in the rim. To correct this, identify the highest point of the wheel (the point with the greatest vertical deviation).

  • Loosen the spoke nipples on the section of the wheel just before the high point of the rim.
  • Tighten the spokes directly after the high point to pull the rim down.
  • Make small adjustments, moving around the wheel, and ensuring even pressure on all spokes.

5. Check Spoke Tension

Once the wheel is close to being true, use a tension meter to check the spoke tension. Ensuring that the tension is consistent across all spokes is crucial for wheel strength and longevity.

  • Tighten or loosen any spokes that show irregular tension to achieve an even balance.
  • Keep in mind that the EXC 1200 SPLINE wheels are designed with specific spoke tension in mind for optimal performance, so don’t exceed recommended tension limits.

6. Recheck the Wheel

After making all the necessary adjustments, spin the wheel again to verify that it is now true. The wheel should spin smoothly, without any wobble or bounce.

  • If the wheel still shows signs of lateral or radial misalignment, repeat the process until the wheel is perfectly true.
  • You can use a ruler or caliper to measure the gap between the rim and the brake pads or the truing stand to ensure uniformity.

Troubleshooting Common Set-Up Issues

Sometimes, issues can arise during the truing process that may require troubleshooting. Here are some common problems and how to resolve them:

1. Persistent Lateral Deviation

If lateral misalignment persists after adjustments, it could be due to uneven spoke tension or a bent rim. Recheck all spoke tensions and ensure they are balanced. If the rim is still not true after adjustments, it may need to be replaced.

2. Radial Misalignment That Won’t Correct

If you are unable to fix a radial hop, inspect the spokes for any damage or breakage. A broken spoke can create an uneven tension, making it impossible to properly true the wheel. Replace any damaged spokes and attempt the truing process again.

3. Excessive Spoke Tension

Too much spoke tension can cause issues with wheel performance, including excessive wheel flex or difficulty in truing. Use a tension meter to measure the tension and ensure you are within the recommended range for the EXC 1200 SPLINE wheels.

Customization and Optimization for Better Performance

To get the most out of your DT Swiss EXC 1200 SPLINE wheels, consider the following customization and optimization tips:

1. Upgrading Spokes and Nipples

The EXC 1200 SPLINE wheels come with high-quality spokes and nipples, but upgrading to titanium or aero spokes can reduce weight and improve aerodynamics. Be sure to choose components that are compatible with the EXC 1200 SPLINE’s design.

2. Wheel Lacing Patterns

While the factory lacing pattern on the EXC 1200 SPLINE wheels is optimal for most riders, you can experiment with different spoke lacing patterns for specific types of riding. For instance, radial lacing is more aerodynamic, while a 2-cross or 3-cross pattern can provide added strength and durability for aggressive riding.

3. Wheel Tension and Riding Style

Adjusting the spoke tension according to your riding style can optimize performance. Higher tension improves stiffness and responsiveness, which is ideal for competitive cycling, while slightly lower tension offers more comfort for long-distance riders.

Compatibility with Other Drivetrain Components

The DT Swiss EXC 1200 SPLINE wheels are compatible with a wide range of road bike drivetrains. However, it’s essential to ensure the compatibility of the wheels with your existing components, such as the cassette, chain, and bottom bracket.

  • Cassette Compatibility: The EXC 1200 SPLINE wheels are designed to work with both Shimano/SRAM and Campagnolo cassettes. Ensure that your cassette type matches the freehub body of the EXC 1200 SPLINE.
  • Brake Compatibility: The EXC 1200 SPLINE wheels come in both rim brake and disc brake options, so make sure you choose the correct version for your bike’s braking system.

By ensuring proper installation, regular maintenance, and occasional adjustments, your DT Swiss EXC 1200 SPLINE wheels will continue to perform at their peak [paid link] for years to come.
