The Race Face Atlas 30 [paid link] wheels are known for their strength, durability, and performance on the trail. Over time, the bearings in your wheels can wear out due to exposure to dirt, moisture, and general use. When this happens, you’ll notice that your wheel’s performance starts to degrade. Replacing the bearings is a straightforward task, but it requires the right tools, knowledge, and care to ensure a smooth replacement. This guide will walk you through the step-by-step process of bearing replacement in your Atlas 30 [paid link] wheels.

Tools Required

  • Bearing puller tool
  • Torque wrench [paid link]
  • Socket set
  • Flathead screwdriver
  • Grease (high-quality bearing grease)
  • 10mm and 15mm wrenches
  • Clean rags or cloth
  • Bearing press [paid link] tool (for reinstallation)
  • Adjustable spanner (optional)

Preparation for Bearing Replacement

Before starting the replacement process, it is essential to prepare your workspace and ensure that all tools are within reach. You should also clean your wheels thoroughly to prevent any debris from contaminating the bearings during the replacement. The work area should be well-lit and clean, allowing you to perform the task efficiently and without distractions.

Removing the Wheel from the Bike

  1. Shift to a Lower Gear: To make the wheel removal easier, shift your drivetrain to the lowest gear.
  2. Release the Wheel from the Bike: Use your 15mm wrench to release the quick release or the thru-axle, depending on your wheel setup.
  3. Remove the Wheel: After loosening the axle, carefully remove the wheel from the bike.

Disassembling the Hub

  1. Remove the End Caps: Most Atlas 30 wheels come with end caps that protect the hub’s bearings. Use a flathead screwdriver or your hands to carefully remove these end caps.
  2. Loosen the Hub’s Nuts: Use a 10mm wrench to remove any nuts securing the hub. This might vary depending on your specific wheel setup, but generally, these nuts are designed to secure the hub to the spokes.
  3. Remove the Freehub Body (if applicable): For wheels with a freehub, remove it by gently pulling it off. Be cautious during this step, as it contains a spring mechanism that can be under tension.

Removing the Old Bearings

Once the hub is fully disassembled, you will need to remove the worn-out bearings.

  1. Inspect the Bearings: Carefully inspect the bearings inside the hub. If they feel rough when turned by hand or have visible damage, they need to be replaced.
  2. Use the Bearing Puller: Place the bearing puller on the inner race of the bearing. Ensure that the puller is well-positioned to extract the bearing without damaging the hub.
  3. Extract the Bearings: Slowly turn the puller to remove the bearing from the hub. Be sure to do this gently to avoid damaging the bearing housing or other internal components.
  4. Clean the Bearing Area: After removing the old bearings, use a clean rag to wipe down the bearing housing. Ensure that no debris or contaminants remain inside the hub.

Installing the New Bearings

With the old bearings removed, it’s time to install the new ones.

  1. Apply Grease to the Bearing Housing: Before inserting the new bearings, apply a light coating of high-quality bearing grease to the bearing housing to prevent corrosion and ensure smooth rotation.
  2. Insert the New Bearings: Carefully place the new bearings into the housing. Use the bearing press [paid link] tool to ensure the bearings are seated correctly. Apply gentle but firm pressure to avoid misalignment.
  3. Verify Bearing Movement: After installation, rotate the bearings by hand to ensure smooth movement. There should be no grinding or roughness.

Reassembling the Hub

After the bearings have been successfully installed, it’s time to put the hub back together.

  1. Reinstall the Freehub Body: If you removed the freehub body earlier, now is the time to reinstall it. Make sure it’s properly aligned and secured.
  2. Reattach the Hub Nuts: Use the 10mm wrench to tighten the nuts that hold the hub in place. Ensure that these are torqued to the manufacturer’s specifications to avoid any issues while riding.
  3. Replace the End Caps: Reinstall the end caps that protect the bearings. Ensure these are seated correctly and securely.

Reinstalling the Wheel

  1. Mount the Wheel: Place the wheel back on the bike, making sure the axle is aligned with the dropouts.
  2. Secure the Axle: Tighten the axle with the 15mm wrench, ensuring it’s torqued correctly to prevent any wobbling or misalignment.
  3. Check the Alignment: Once the wheel is secured, check that the wheel spins freely and that the hub rotates smoothly.

Testing the Wheel

Before hitting the trails, it’s important to ensure that the new bearings are functioning properly.

  1. Spin the Wheel: Rotate the wheel by hand to check for smoothness. There should be no grinding noises or resistance.
  2. Ride the Bike: After the installation, take your bike for a short ride. Pay attention to the wheel’s performance, and listen for any unusual sounds or resistance.

Troubleshooting Common Bearing Replacement Issues

  1. Bearings Not Spinning Smoothly: If the new bearings are not spinning smoothly, ensure that the bearing housing is clean and free of debris. Double-check that the bearings are seated properly and not misaligned.
  2. Wheel Wobble: If the wheel wobbles after installation, check the axle tension and alignment. A loose or improperly torqued axle can cause wobbling.
  3. Excessive Noise: If you hear noise after the replacement, recheck the grease level and ensure that the end caps are installed properly. Sometimes, improper installation of the freehub can also cause noise.

Conclusion

Replacing the bearings in your Race Face Atlas 30 wheels can significantly improve their performance and longevity. By following the steps outlined in this guide, you’ll be able to restore smoothness and efficiency to your wheels, ensuring a better ride. With the right tools and a bit of patience, bearing replacement is a manageable task that any cyclist can handle. Whether you’re maintaining your wheels for competitive use or just for regular trail rides, this process will help you keep your Atlas 30 wheels in top condition for years to come.
