The DT Swiss XRC 1200 SPLINE [paid link] wheels are a high-performance option designed for serious road cyclists. One critical aspect of maintaining these wheels is ensuring the bearings are in optimal condition. Over time, bearings may wear out due to regular use or exposure to elements such as water, dirt, or excessive heat. This guide will provide a step-by-step process for replacing the bearings in the DT Swiss XRC 1200 SPLINE [paid link] wheels. Proper bearing maintenance is essential for smooth rolling, reducing drag, and extending the life of your wheels.

Tools Required

  • Bearing puller or an appropriate bearing removal tool
  • 10mm hex key
  • 5mm Allen key
  • Torque wrench [paid link]
  • Grease (preferably high-quality bike-specific grease)
  • A small hammer (if necessary for bearing removal)
  • Plastic or wooden mallet (for bearing installation)
  • Rags for cleaning
  • New bearings (specific to the XRC 1200 SPLINE)

Preparation

Before beginning, ensure you have a clean and stable workspace. Clean the wheels and remove any dirt or debris. You should also gather all the required tools and ensure the new bearings are compatible with the XRC 1200 SPLINE wheels. For this model, DT Swiss typically uses specific bearings, so confirm their specifications for proper replacement.

Step 1: Remove the Wheel from the Bike

To start, remove the wheel from your bike. For the rear wheel, it’s important to remove the cassette before proceeding with any further disassembly. This will allow you to work directly on the hub where the bearings are located. For the front wheel, simply remove it from the fork.

For Rear Wheel:

  1. Remove the quick release skewer or thru-axle, depending on your bike.
  2. Carefully remove the rear wheel from the frame.
  3. Use a cassette removal tool to remove the cassette if necessary.

For Front Wheel:

  1. Remove the quick release skewer or thru-axle.
  2. Take the wheel off the fork dropouts.

Step 2: Identify and Access the Bearings

The XRC 1200 SPLINE wheels have sealed hubs, meaning the bearings are housed inside the hub and are protected by a series of seals. Depending on the hub design, you may need to remove certain covers or the freehub body to access the bearings.

  1. For the front wheel, the bearings are usually accessed by removing the end caps on each side of the hub.
  2. For the rear wheel, remove the freehub body after removing the cassette to reach the internal bearings.

Using your 10mm hex key, unscrew any bolts that are securing the hub parts. Be sure to keep track of the order and orientation of the parts you are removing for reassembly.

Step 3: Remove the Bearings

Once you have access to the bearings, the next step is removal. Depending on the tightness of the bearings and the hub design, you may need to use a bearing puller tool to safely extract the old bearings.

  1. Use the bearing puller to carefully remove the bearings from the hub shell. Be gentle to avoid damaging the hub’s internal surface.
  2. In some cases, you may need to use a small hammer with a wooden or plastic mallet to tap the bearing out if it is stuck. Avoid using a metal hammer as it can damage the bearing surfaces or hub.

If the bearings are extremely tight, try applying a bit of heat using a heat gun to expand the hub shell slightly, which can make removal easier. Be cautious to avoid overheating, which could damage the hub material or seals.

Step 4: Clean the Hub

Before installing the new bearings, it’s essential to clean the hub thoroughly. Use a rag to remove any grease, dirt, or debris from the hub’s interior. This will ensure that the new bearings sit in a clean, smooth environment, reducing the risk of contamination and premature wear.

Step 5: Install the New Bearings

Now it’s time to install the new bearings. Ensure that the new bearings are properly sized for the XRC 1200 SPLINE model.

  1. Apply a small amount of bike-specific grease to the bearing seats inside the hub to facilitate smooth installation and prevent corrosion.
  2. Carefully press the new bearings into place using your bearing press [paid link] tool or a plastic mallet. Tap them gently until they are seated properly. Make sure the bearings are aligned and sitting flush within their recesses. If using a mallet, avoid hitting the bearing directly with metal; use a plastic or wooden piece as a buffer.

Make sure that the orientation of the bearings matches the original configuration, and avoid forcing them in. If they do not fit easily, recheck the bearing size and alignment.

Step 6: Reassemble the Hub

Once the bearings are installed, you can begin reassembling the hub. Follow the order of disassembly to ensure that all parts go back into their correct positions.

  1. Reinstall any seals, freehub body, and end caps, ensuring they fit snugly.
  2. Tighten all bolts using the appropriate torque specifications for the XRC 1200 SPLINE wheels. This is important to avoid damaging the hub or causing the wheel to fail during use.

Step 7: Install the Wheel Back on the Bike

Once the bearing replacement and hub reassembly are complete, it’s time to reinstall the wheel back onto your bike.

For Rear Wheel:

  1. Reinstall the cassette if it was removed.
  2. Place the rear wheel back into the frame, ensuring that the chain is properly routed over the cassette.
  3. Secure the wheel with the skewer or thru-axle.

For Front Wheel:

  1. Place the front wheel back into the fork dropouts.
  2. Secure the wheel with the skewer or thru-axle.

Step 8: Test the Wheel

After reassembling the wheel and reinstalling it on the bike, it is crucial to test the bearing performance. Spin the wheel and listen for any unusual sounds, such as grinding or roughness, which may indicate improper installation or defective bearings.

Check that the hub spins smoothly and without resistance. If there is any roughness or play in the bearings, recheck the installation and ensure the bearings were installed correctly.

Troubleshooting Common Issues

Issue: Bearing Noise

If the wheel is making noise even after bearing replacement, it could be due to improper installation or contamination of the bearings during installation. Recheck the bearing seats, clean the hub thoroughly, and ensure that the bearings are properly greased.

Issue: Rough Rotation

If the wheel is not spinning smoothly, ensure the bearings are properly seated and not too tight. Over-tightening the hub bolts can create friction, preventing smooth movement. Adjust the tension accordingly.

Conclusion

Replacing the bearings in the DT Swiss XRC 1200 SPLINE wheels is a straightforward task if done carefully and methodically. By following this step-by-step guide, you can ensure that your wheels continue to perform at their best, delivering smooth and efficient rides for years. Regular maintenance and bearing replacement are essential for prolonging the lifespan of your wheels and ensuring optimal performance.
