Installation and Adjustment

Installing the EXC 1200 SPLINE Wheels

Proper installation is critical to ensure your DT Swiss EXC 1200 SPLINE wheels perform optimally from the start. Follow these steps for a secure installation:

  1. Prepare the Bike:
    • Ensure your frame is compatible with the EXC 1200 SPLINE wheels. These wheels typically feature a 12mm through-axle, so your frame must support that standard.
    • Clean the dropouts on your frame and fork thoroughly to avoid dirt or debris from causing damage during installation.
  2. Install the Front Wheel:
    • Insert the front wheel into the fork, ensuring the quick release or thru-axle fits securely into the designated slots.
    • Tighten the axle or quick release mechanism to the correct torque value (check manufacturer specifications for exact torque).
  3. Install the Rear Wheel:
    • Position the rear wheel into the frame, aligning the cassette with the derailleur hanger.
    • Tighten the thru-axle or quick release on the rear wheel. Again, check torque specifications to ensure it is fastened correctly.
  4. Check Brake Rotor Alignment:
    • If your EXC 1200 SPLINE wheels come with disc brakes, ensure the rotor is aligned with the caliper. A misaligned rotor can lead to brake rubbing and poor performance.

Adjusting the Hub Bearings

Regular hub maintenance ensures smooth performance and prevents premature wear. The EXC 1200 SPLINE wheels feature DT Swiss’ Ratchet System, known for its reliability and efficiency. Follow these steps for adjusting the bearings:

  1. Check the Bearing Condition:
    • Spin the wheel by hand and check for any roughness or resistance in the hub. If the hub feels gritty or difficult to rotate, it may be time to service the bearings.
  2. Disassemble the Hub:
    • Using a 5mm Allen key, remove the end cap and the axle from the hub.
    • Take out the ratchet system and inspect the bearings for any signs of wear or contamination.
  3. Clean and Lubricate:
    • Clean all the components thoroughly with a degreaser.
    • Apply a thin layer of appropriate grease to the bearings and the ratchet system before reassembling the hub.
  4. Reassemble the Hub:
    • Carefully reassemble the hub components, ensuring everything is seated correctly.
    • Tighten the axle and end caps according to the recommended torque values.

Maintenance Tips for Long-Lasting Performance

Keeping the Wheels Clean

Maintaining clean wheels not only enhances performance but also prevents unnecessary wear. Regular cleaning will also help you spot issues early, such as cracks in the rim or damage to the spokes.

  1. Use Mild Soap and Water:
    • Avoid harsh chemicals, as they can damage the finish of your EXC 1200 SPLINE wheels. Use mild soap and water to clean the rims and hubs.
    • Gently wipe the spokes and rim edges with a soft cloth to remove dirt.
  2. Drying:
    • After cleaning, use a clean, dry cloth to wipe down the wheel and ensure no moisture is trapped in the components, which could cause rust over time.
  3. Brake Pads and Rotor Cleaning:
    • For disc-brake models, clean the brake rotors with isopropyl alcohol. Ensure there is no oil or grime on the rotor surface, as this can reduce braking efficiency.

Lubrication and Grease Application

Lubricating the moving parts of your wheels is essential to keep them operating smoothly. Focus on the following areas:

  1. Hubs:
    • The ratchet mechanism and bearings need periodic lubrication. Apply a light layer of lubricant to prevent wear and enhance the freehub’s engagement.
  2. Spokes:
    • While spokes don’t require regular lubrication, applying a small amount of spoke grease during installation can prevent them from seizing over time.
  3. Quick Release or Thru-Axle:
    • Lightly grease the contact points of your quick release or thru-axle to make sure they don’t bind or become difficult to remove.

Troubleshooting Common Set-Up Issues

1. Wheel Wobble or Uneven Rotations

If you experience a wobble while riding, or the wheel doesn’t rotate smoothly, there could be an issue with the spoke tension or the hub.

  • Spoke Tension:
    • Check the spoke tension using a spoke wrench. Uneven spoke tension can lead to an out-of-true wheel. Use a truing stand to check for true alignment, and adjust spoke tension accordingly.
  • Hub Maintenance:
    • If the issue persists, it may be a hub-related problem. Check the hub bearings and grease the components. If bearings feel rough or gritty, they may need to be replaced.

2. Noisy Freehub

If your freehub produces excessive noise or has poor engagement, the issue likely lies with the ratchet mechanism or lack of lubrication.

  • Cleaning the Ratchet Mechanism:
    • Remove the freehub body and clean the ratchet mechanism thoroughly. Re-grease the pawls and reassemble the freehub carefully to ensure proper function.

3. Braking Issues

For those using disc brakes, ensure the rotor is not warped or rubbing against the brake pads.

  • Rotor Alignment:
    • If you hear constant rubbing, check the rotor alignment with the brake caliper. Use a rotor truing tool to bend the rotor back into shape if necessary.
  • Brake Pad Wear:
    • Inspect the brake pads for wear and replace them if they are too thin.

Customization and Optimization for Better Performance

The DT Swiss EXC 1200 SPLINE wheels can be further customized for specific riding preferences and conditions. Here’s how:

1. Tire Selection

Choosing the right tire width and pressure can significantly affect your ride quality. Wider tires provide better comfort and grip, while narrower tires reduce rolling resistance and improve aerodynamics.

  • Tire Pressure:
    • Always maintain the recommended tire pressure for your riding conditions. Lower pressures are better for rougher terrain, while higher pressures are suited for smooth, fast roads.

2. Upgrading Hubs

If you are looking for a quieter, more responsive ride, consider upgrading the freehub system to one with a higher engagement rate. The EXC 1200 SPLINE hubs are already quite efficient, but higher-end versions may provide quicker power transfer.

3. Spoke Lacing

Experiment with different spoke lacing patterns for strength and weight savings. The DT Swiss wheels are versatile [paid link], and the spoke pattern can influence how the wheel handles under different loads.

Compatibility with Other Drivetrain Components

The DT Swiss EXC 1200 SPLINE wheels are compatible with a wide range of drivetrains. However, it’s crucial to confirm compatibility with your current setup.

1. Shimano/SRAM Compatibility

The EXC 1200 SPLINE wheels can easily accommodate both Shimano and SRAM 11-speed and 12-speed drivetrains. Ensure the cassette freehub body is compatible with your cassette type.

2. Compatibility with Brake Systems

These wheels are compatible with both rim and disc brake systems. If using disc brakes, ensure the rotor size matches your frame’s specifications.

3. Axle Compatibility

The wheels typically come with a 12mm through-axle. Ensure that your frame and fork support the corresponding axle standard. You may need to purchase additional adapters for compatibility with different axle types.
