Tools Required

  • 5mm Allen wrench [paid link]
  • 3mm Allen wrench [paid link]
  • Torque wrench [paid link]
  • Tire levers
  • Rim tape (if needed)
  • Valve core remover tool
  • Spoke tension meter (optional)
  • Tubeless tire sealant (for tubeless setups)
  • Disc brake rotor adapter (if applicable)
  • Bicycle stand (optional but recommended)

Installation of EXC 1200 SPLINE Wheels

Installing the DT Swiss EXC 1200 SPLINE wheels on your bike requires a few key steps. Follow the instructions carefully to ensure proper setup and maximize the performance of your wheels.

Step 1: Preparing the Bike Frame

Before installing the wheels, ensure that your bike’s dropouts or axle standards are compatible with the EXC 1200 SPLINE wheels. The EXC 1200 SPLINE features a 12mm thru-axle compatibility, but you should confirm your frame is designed for this standard. If your frame uses quick release, make sure you have the appropriate adapters.

Step 2: Installing the Rear Wheel

  1. Insert the rear wheel into the bike frame, aligning the cassette with the freehub body.
  2. If you are using a thru-axle, slide it through the wheel hub and secure it tightly.
  3. Ensure the wheel sits correctly in the dropouts and that the axle is properly tightened to the manufacturer’s recommended torque specification. Use a torque wrench [paid link] for accurate installation.

Step 3: Installing the Front Wheel

  1. Insert the front wheel into the fork, ensuring the axle is fully seated in the dropouts.
  2. Tighten the axle according to the recommended torque values.
  3. Double-check that the wheel spins freely and that the rotor (if installed) does not rub against the brake pads.

Step 4: Installing the Disc Brake Rotors (if applicable)

  1. If your EXC 1200 SPLINE wheels are equipped with disc brake hubs, install the rotors onto the wheel hub. Use a 6-bolt pattern and align the rotor holes with the corresponding holes on the hub.
  2. Tighten the bolts using a torque wrench to ensure the correct torque values. The recommended torque for disc rotor bolts is usually 6–8 Nm.

Maintenance of EXC 1200 SPLINE Wheels

Regular maintenance of the DT Swiss EXC 1200 SPLINE wheels is essential to keep them performing optimally for years. These wheels are designed to handle demanding riding conditions, but proper care will ensure long-term durability and safety.

1. Cleaning the Wheels

Clean your EXC 1200 SPLINE wheels after every ride to prevent dirt and grime buildup that could cause friction or wear on the hubs and rims. Use mild soap, water, and a soft brush to remove debris. Be sure to avoid using harsh chemicals that could damage the wheel’s surface or bearings.

2. Checking the Hubs

The EXC 1200 SPLINE wheels are equipped with DT Swiss hubs, which require minimal maintenance. However, it’s important to check the hubs periodically for any play or excessive wear. If you notice any unusual sounds or resistance during wheel rotation, it may be a sign that the bearings need servicing. To maintain smooth performance, lubricate the hubs annually with a high-quality grease, especially if you often ride in wet or muddy conditions.

3. Tubeless Setup Maintenance

If you’ve set up your wheels tubeless, it’s crucial to check the tire sealant levels every few months. Add more sealant if necessary, especially if you notice any tire pressure loss. The EXC 1200 SPLINE is compatible with tubeless tires, which offer improved ride quality and puncture protection.

4. Spoke Tension and Truing

Inspect the spoke tension regularly. A spoke tension meter can be used to check consistency across all spokes. If you notice any issues with the wheel truing, take your bike to a professional mechanic or perform minor adjustments using a spoke wrench. Proper spoke tension ensures optimal wheel performance and longevity.

Troubleshooting Common Set-Up Issues

Despite being a premium product, the DT Swiss EXC 1200 SPLINE wheels may occasionally present some issues. Below are a few common problems and their solutions.

Issue 1: Hub Drag or Resistance

If you notice resistance when spinning the wheels, it may be due to:

  • A tight thru-axle or improperly installed hub.
  • Insufficient lubrication of the hub bearings.
    To fix this, ensure that the axle is not overtightened and that the bearings are adequately lubricated.

Issue 2: Brake Rotor Rub

If the disc brake rotor rubs against the brake pads, it could be due to:

  • Misalignment of the rotor during installation.
  • The rotor being slightly bent.
    To resolve this, check that the rotor is securely attached to the hub and that it is true. If bent, carefully straighten it using a rotor truing tool.

Issue 3: Loss of Tire Pressure (for Tubeless Setup)

If your tire pressure drops frequently:

  • Inspect the tire for punctures or sealant leaks.
  • Check the valve core to ensure it is properly tightened and sealed.
    If necessary, replace the valve core or add more sealant to the tire.

Customization and Optimization for Better Performance

The DT Swiss EXC 1200 SPLINE wheels are already optimized for excellent performance, but customization can further enhance your ride experience. Here are a few ways to optimize the wheels:

1. Tire Selection

The choice of tire significantly affects the performance of your EXC 1200 SPLINE wheels. Lighter tires with lower rolling resistance can improve speed and efficiency, while wider tires can enhance comfort and grip, especially on rougher terrain. Make sure to select a tire that matches your riding style and conditions.

2. Adjusting Spoke Tension

Adjusting the spoke tension slightly can change the ride quality of the wheels. Higher spoke tension generally leads to a stiffer wheel, which may improve responsiveness but reduce comfort. Conversely, lower spoke tension offers a more forgiving ride, though it may sacrifice some performance. Experiment with different tension levels to find the balance that works best for you.

3. Rotor Size Adjustment

If you feel that your braking performance could improve, consider upgrading to larger rotors. The EXC 1200 SPLINE wheels support up to 180mm rotors, which can increase stopping power, especially on steep descents. Larger rotors provide better heat dissipation, reducing the risk of brake fade.

Compatibility with Other Drivetrain Components

The EXC 1200 SPLINE wheels are compatible with most modern road bike drivetrains, but compatibility with other components must be verified before installation. The wheels come with a DT Swiss 12x100mm and 12x142mm thru-axle setup and can be paired with Shimano, SRAM, and Campagnolo drivetrains. For compatibility with specific cassettes, the freehub body must be matched to the appropriate driver (Shimano/SRAM or Campagnolo).

Make sure to check the number of gears on your cassette and ensure that your derailleur can accommodate the range. Additionally, if you use disc brakes, confirm that your bike frame and fork are compatible with the rotor mount standards (6-bolt or Centerlock).

Comparison with Similar Models

While the DT Swiss EXC 1200 SPLINE wheels are designed for high-performance road cycling, there are other wheel models from DT Swiss and other brands that cater to similar needs. Here’s a brief comparison to help you choose the best option:

DT Swiss PRC 1100 DICUT vs. EXC 1200 SPLINE

The DT Swiss PRC 1100 DICUT wheels are a step up in terms of aerodynamics, featuring deeper rims and optimized for time trials or triathlons. However, the EXC 1200 SPLINE is more versatile [paid link], with a better balance between weight, strength, and cost. The PRC 1100 wheels are slightly lighter but are best suited for flat or fast terrain.

Zipp 303 Firecrest vs. EXC 1200 SPLINE

Zipp’s 303 Firecrest wheels are known for their aerodynamics and wide rims, designed for gravel and rough roads. The EXC 1200 SPLINE wheels are a better choice for riders seeking a more versatile [paid link] wheel that performs well across a variety of road conditions while still maintaining excellent stiffness and power transfer.

Conclusion

The DT Swiss EXC 1200 SPLINE wheels are an excellent choice for cyclists who want a combination of performance, durability, and versatility.
