The DT Swiss EX 1700 SPLINE [paid link] wheels are a popular choice among cyclists for their durability and performance, especially for mountain and gravel bikes. One of the key benefits of these wheels is their tubeless compatibility, which allows riders to set up their tires without the need for inner tubes. Tubeless setups offer several advantages, such as reduced punctures, better grip, and the ability to run lower tire pressures. This guide provides a detailed, step-by-step process for setting up your EX 1700 SPLINE [paid link] wheels with a tubeless system.

Tools Required

  • EX 1700 SPLINE wheels
  • Tubeless-ready tires
  • Tubeless valve stems
  • Tubeless rim tape
  • Tire levers
  • Floor pump with a high-pressure capacity
  • Liquid tubeless sealant (suitable for your tire type)
  • Soapy water (for sealing)
  • Scissors (for trimming rim tape)

Preparing the Wheels for Tubeless Setup

Before you begin the tubeless setup process, it’s crucial to properly prepare your EX 1700 SPLINE wheels. This ensures the tubeless system functions as intended and that the tire properly seals against the rim.

  1. Remove the Existing Tire (if applicable): If you have any existing tires mounted on the wheel, remove them carefully using tire levers. Be mindful not to damage the rim or the valve stem.
  2. Clean the Rim: Thoroughly clean the rim of the EX 1700 SPLINE with a clean cloth to remove any dirt, grease, or residue. This step helps ensure proper adhesion for the tubeless tape and sealant.
  3. Inspect the Rim: Ensure that the inner rim surface is free of any sharp edges or debris that could puncture the tubeless tire. Check for any visible cracks or damage to the rim that may affect the setup.

Installing Tubeless Rim Tape

The EX 1700 SPLINE wheels are designed to be tubeless-ready, but they still require a proper tubeless tape installation to seal the rim bed. Follow these steps carefully to install the tape correctly.

  1. Choose the Correct Rim Tape Width: The EX 1700 SPLINE rims are designed for 30mm-wide internal rims. Ensure you have tubeless rim tape that matches the width of the rim to ensure a secure and tight seal.
  2. Start at the Valve Hole: Position the tape at the valve hole and begin wrapping it around the rim. Make sure the tape overlaps slightly at the valve hole to create a complete seal.
  3. Apply Even Pressure: While wrapping the tape around the rim, apply consistent, even pressure to ensure that the tape adheres firmly to the rim. This will prevent any gaps that might lead to air leaks.
  4. Trim Excess Tape: Once you’ve wrapped the tape around the entire rim, trim any excess tape using scissors. Make sure the tape is flush with the rim edge to prevent any interference when mounting the tire.

Installing the Tubeless Valve Stem

The next step is to install the tubeless valve stem. This part is crucial for ensuring a tight seal between the wheel and the valve, which allows for easy inflation and tire maintenance.

  1. Create a Hole in the Rim Tape: Use a sharp object (like a small knife or hole punch) to make a hole in the center of the rim tape at the valve hole. Be careful not to damage the rim.
  2. Install the Valve Stem: Insert the tubeless valve stem through the hole in the rim tape and push it through until it sits securely. Tighten the nut on the valve stem to hold it in place, ensuring there is no gap between the valve and the tape.

Mounting the Tubeless Tire

With the rim and valve prepared, it’s time to mount the tubeless tire on your EX 1700 SPLINE wheel.

  1. Place the Tire on the Rim: Begin by placing one side of the tire onto the rim. Work your way around the wheel, ensuring that the tire bead is securely seated on the rim.
  2. Seat the Other Side: Carefully work the other side of the tire onto the rim. If you find resistance, use tire levers to help, but be gentle to avoid damaging the tire or rim.
  3. Check for Proper Seating: Before moving on to the next step, check that both beads of the tire are evenly seated on the rim. The tire should sit snugly against the rim on both sides.

Adding Tubeless Sealant

Adding the correct amount of tubeless sealant is critical for ensuring a good seal and preventing air leaks. The amount of sealant required depends on the tire size and manufacturer recommendations.

  1. Shake the Sealant: Shake the tubeless sealant bottle thoroughly to ensure even consistency.
  2. Pour Sealant into the Tire: Remove the valve core using a valve core remover tool. Pour the recommended amount of sealant into the tire, usually around 2-3 ounces for most road and gravel tires.
  3. Reinstall the Valve Core: After adding the sealant, reinsert the valve core and tighten it securely. Be sure that the valve core is fully seated to avoid leaks.

Inflating the Tire

Inflating a tubeless tire can be tricky if you don’t have a high-pressure floor pump or a compressor. To get the tire bead to pop into place and form a secure seal, follow these steps.

  1. Use a High-Pressure Pump: Attach your floor pump to the valve stem and begin inflating the tire. If you’re using a hand pump, make sure it can handle high-pressure inflation (typically 60-80 PSI for tubeless setups).
  2. Listen for the Bead to Pop: As you inflate, listen for the tire bead to pop into place. You may need to apply additional soapy water to the rim to help the bead seat properly.
  3. Continue Inflating: Once the bead is seated, continue inflating until you reach your desired tire pressure. Remember, lower pressures are generally better for grip, but they should still be within the recommended range for your tire.

Checking for Leaks

After inflation, it’s important to check for any potential leaks in the system. A well-installed tubeless setup will be airtight, but leaks can occur if the tape, valve, or tire weren’t installed properly.

  1. Inspect the Tire: Rotate the wheel and look for any signs of air escaping around the valve or tire beads. If you hear hissing or see air bubbles forming, it’s a sign that there’s a leak.
  2. Apply Soapy Water: If you suspect a leak, spray soapy water on the valve and tire bead. The bubbles will help identify the source of the leak.
  3. Fix Leaks if Necessary: If you find a leak, you may need to adjust the valve, reseat the tire bead, or add more sealant to ensure a proper seal.

Final Adjustments

Once your tire is properly sealed and inflated, make sure to double-check the overall setup.

  1. Check Tire Pressure: Recheck the tire pressure after a few minutes to ensure it hasn’t dropped. If necessary, top up the pressure to your preferred PSI.
  2. Perform a Test Ride: Take your bike for a short test ride to ensure that the tire performs as expected. Listen for any unusual noises or feel for any loss of pressure.

Troubleshooting Common Tubeless Setup Issues

Despite the benefits, tubeless setups can sometimes present challenges. Here are some common issues and how to resolve them:

  • Tire Bead Not Seating: If the tire bead refuses to seat, try using a tire bead seating tool or re-inflate with a compressor to give it an extra burst of air. Soapy water can also help lubricate the bead.
  • Leaks Around the Valve: If air leaks from around the valve, check the valve core for tightness, and ensure the valve stem is properly installed and seated.
  • Sealant Clumps: Occasionally, sealant can form clumps that block the valve or create uneven sealing. Ensure the sealant is well-shaken before installation, and replace it if it becomes thick or expired.

Conclusion

Setting up your DT Swiss EX 1700 SPLINE wheels with a tubeless system can greatly enhance your riding experience by reducing punctures and improving performance. By following this detailed guide, you’ll be able to install, adjust, and maintain your tubeless setup with confidence. Regular checks and sealant maintenance will keep your wheels in top condition, ensuring a smooth and reliable ride for many miles to come.
