Replacing spokes on your DT Swiss H 1900 SPLINE Hybrid [paid link] wheels can be a crucial skill to ensure your wheels maintain their integrity and performance. Over time, spokes can break due to wear and tear, impacts, or improper tensioning. This guide will walk you through the process of replacing the spokes on your H 1900 SPLINE Hybrid [paid link] wheels, covering installation, adjustment, and maintenance to keep your wheels in top shape.

Tools Required

  • Spoke wrench
  • 3mm and 5mm Allen wrenches [paid link]
  • Needle nose pliers
  • Tension meter (optional but recommended)
  • Spoke remover tool (optional)
  • Truing stand (for wheel alignment)
  • Lube or anti-seize compound
  • Replacement spokes (specific to the H 1900 SPLINE Hybrid)
  • Spoke nipples (matching the original ones)
  • Tire levers (if removing the tire is necessary)

Preparing the Wheel for Spoke Replacement

Before starting, it’s essential to prepare your wheel for the repair process.

1. Remove the Wheel from the Bike

  • Use a 5mm Allen wrench [paid link] to remove the wheel from the bike.
  • If you’re working on the rear wheel, you might need to remove the cassette as well. Use a cassette tool to safely remove it.

2. Inspect the Wheel

  • Check the overall condition of the wheel, including any other broken or loose spokes. Take note of any damage to the rim or hub that could affect the replacement process.
  • If the wheel is out of true, use a truing stand to assess how much adjustment is needed before starting.

3. Remove the Tire

  • If the broken spoke is on the rim side, you might want to remove the tire to make it easier to access the spoke nipples. Use tire levers to carefully remove the tire.

Removing the Broken Spoke

Before replacing the spoke, you’ll need to remove the broken one.

1. Loosen the Spoke Tension

  • Use the spoke wrench to carefully loosen the spoke that is broken. Work slowly to avoid damaging adjacent spokes.

2. Remove the Broken Spoke

  • Once the spoke is loose, carefully remove the spoke nipple from the rim. Use needle nose pliers if necessary to remove any part of the spoke still threaded through the nipple.
  • If the spoke is stuck or tightly wedged in place, use a spoke remover tool or gently wiggle the spoke out of the nipple.

Installing the New Spoke

Now that the broken spoke is removed, it’s time to install the new one.

1. Prepare the New Spoke

  • Choose a replacement spoke that matches the length, gauge, and threading of the original. The H 1900 SPLINE Hybrid uses a specific spoke size, so ensure you select the correct one.
  • Apply a small amount of lube or anti-seize compound to the threads of the spoke to prevent corrosion and ensure smoother threading.

2. Insert the New Spoke into the Hub

  • Thread the new spoke into the corresponding hole in the hub. Ensure the spoke is properly aligned with the spoke holes to maintain proper tension and alignment.
  • If you’re working on the rear wheel, make sure the spoke is inserted in the correct position for the freehub, as this can affect the overall alignment and tension.

3. Insert the Spoke Nipple

  • Once the spoke is threaded through the hub and the rim, insert the spoke nipple into the corresponding hole in the rim.
  • Tighten the spoke nipple by hand until it is just snug. Be careful not to over-tighten at this stage.

Tensioning the Spoke

Proper tension is essential to keep the wheel true and prevent future breakages.

1. Initial Tension

  • Use the spoke wrench to gradually tighten the spoke nipple. Start by tightening the nipple until it is secure, but do not over-tighten it.
  • Work around the wheel, tightening each spoke a little at a time to ensure even tension. If you’re replacing multiple spokes, make sure to replace them one by one and gradually increase the tension of each.

2. Use a Tension Meter

  • For precise tension, use a tension meter to check the tension of each spoke. The goal is to achieve consistent tension across all spokes on the wheel, ensuring it’s within the recommended range for your wheel model.
  • DT Swiss recommends a spoke tension of around 120-140 kgf for the H 1900 SPLINE Hybrid wheels, but always consult the manufacturer’s recommendations for your specific wheel model.

Truing the Wheel

Once the new spoke is in place and properly tensioned, you’ll need to true the wheel to ensure it spins smoothly.

1. Check for Lateral and Radial Truing

  • Place the wheel in a truing stand, and check for lateral (side-to-side) and radial (up-and-down) truing.
  • Use the truing stand’s gauge to monitor the wheel’s movement as it rotates. If the wheel is out of true, adjust the tension of the spokes accordingly.

2. Adjust the Spokes

  • If the wheel is laterally out of true, tighten the spokes on one side and loosen the spokes on the opposite side. Make small adjustments to avoid causing the wheel to become too tight on one side.
  • For radial truing, ensure the rim is evenly spaced from the hub across its circumference.

3. Final Check

  • Once the wheel is true, check again with the tension meter to ensure the tension is still within the correct range.
  • Spin the wheel and observe if it runs smoothly without wobbling or rubbing against the brake pads.

Reinstalling the Wheel

Once your spoke replacement is complete, reinstall the wheel onto your bike.

1. Reinstall the Tire

  • If you removed the tire, reinstall it onto the rim, ensuring it is seated properly.
  • Inflate the tire to the recommended pressure and check for any bulges or inconsistencies.

2. Reinstall the Cassette (if applicable)

  • If you removed the cassette from the rear wheel, reinstall it carefully using the cassette tool.

3. Reinstall the Wheel on the Bike

  • Reinstall the wheel onto the bike frame and ensure it is properly secured with the quick release or through-axle, depending on your bike’s setup.

Troubleshooting Common Set-Up Issues

Even with the best effort, some issues may arise during or after spoke replacement. Here are some common problems and solutions.

1. Wheel is Still Out of True After Replacement

  • If the wheel remains out of true, it may indicate uneven spoke tension. Recheck the spoke tension with a tension meter, and adjust the spokes incrementally until the wheel is true.

2. Spoke Breaks Again Quickly

  • If the new spoke breaks soon after replacement, it could indicate improper tensioning or a damaged rim. Ensure the spoke tension is consistent across all spokes and that the rim is free of cracks.

3. Noise or Creaking

  • A creaking noise may occur if the spoke nipples are not properly lubricated or if the spokes were not tensioned evenly. Double-check all spoke nipples for tightness and lubrication.

Maintenance Tips for Longevity

To extend the life of your H 1900 SPLINE Hybrid wheels, regular maintenance is crucial.

  • Periodically check spoke tension and truing, especially after riding on rough terrain or after a crash.
  • Keep the wheels clean and free of debris, as dirt can wear down the spokes and nipples.
  • Lubricate the spoke nipples during each maintenance check to prevent rusting and binding.

By following these steps, you can replace the spokes on your H 1900 SPLINE Hybrid wheels and ensure they continue to perform at their best. With proper maintenance and attention, your wheels will provide reliable performance for many rides to come.
