Industry Nine’s EN355 Hydra [paid link] wheels are designed to be compatible with tubeless tires, making the setup process relatively straightforward. This guide provides step-by-step instructions for installing, adjusting, and maintaining a tubeless system on your EN355 Hydra wheels, with insights on troubleshooting common issues and optimizing your setup for improved performance.

Tools Required

• Tubeless-compatible tires
• EN355 Hydra wheels
• Tubeless rim tape (if not pre-installed)
• Tubeless valve stems
• Sealant (latex-based recommended)
• Tire levers
• Floor pump or compressor
• Valve core remover (optional)
• Isopropyl alcohol or cleaning solution
• Cloth or towel
• Rim tape cutter or scissors (if rim tape needs to be applied)

Preparing the EN355 Hydra Wheels

Before you begin setting up your tubeless system, it’s essential to ensure that your EN355 Hydra wheels are ready for the process.

Clean the Rim

Begin by cleaning the rim of the EN355 Hydra wheels. Dirt or debris on the rim can affect the adhesion of the tubeless tape and cause air leaks. Use a clean cloth and some isopropyl alcohol to wipe down the entire rim surface thoroughly. This step will ensure a tight seal once the rim tape is applied.

Check for Pre-installed Rim Tape

Many EN355 Hydra wheels come with tubeless rim tape pre-installed. If your wheels do not have the tape already in place, you will need to apply it yourself. The tape should cover the entire inner surface of the rim and form a smooth, even layer without any gaps or wrinkles.

Installing the Tubeless Rim Tape

If your EN355 Hydra wheels require new rim tape, follow these steps:

1. Cut a piece of tubeless rim tape long enough to cover the entire inner circumference of the rim.
2. Start at the valve hole and apply the tape, stretching it slightly as you go.
3. Ensure that the tape is applied smoothly without any folds. Use your fingers to press the tape into the rim to eliminate any air bubbles.
4. Overlap the tape by about 1 inch to ensure complete coverage.
5. Once applied, use a tire lever or other tool to press the edges of the tape into the rim, ensuring a good bond.

Installing the Tubeless Valve Stems

Once the rim tape is in place, the next step is to install the tubeless valve stems.

1. Align the valve stem hole on the rim with the valve hole on the rim tape.
2. Insert the valve stem into the hole and tighten the locknut on the outside of the rim.
3. Ensure the valve is seated securely and that there is no gap around the valve stem.

Adding the Tubeless Sealant

The next step is to add tubeless sealant. Sealant helps to form an airtight seal between the tire and rim and can seal small punctures as they occur.

1. Remove the valve core using a valve core remover tool.
2. Shake the sealant bottle well to ensure it is evenly mixed.
3. Add the recommended amount of sealant through the valve stem. The amount will vary depending on the tire size but typically ranges between 2 to 4 ounces (60-120 ml).
4. Replace the valve core once the sealant has been added.

Installing the Tubeless Tire

Now that the rim tape, valve stem, and sealant are in place, it’s time to install the tubeless tire onto the EN355 Hydra wheel.

1. Position the tire on the rim and ensure that the bead (the edge of the tire) is seated properly inside the rim.
2. Work the tire onto the rim using your hands or tire levers. Start at the valve area and gradually work your way around the wheel.
3. Once the tire is mostly in place, ensure that the tire bead is evenly seated on both sides of the rim.

Seating the Tire Bead

With the tire in place, the next step is to seat the tire bead. This step is crucial for creating an airtight seal.

1. Use a floor pump or compressor to inflate the tire. You may need to use a high-volume pump to quickly inflate the tire and seat the bead.
2. As you inflate, the bead will pop into place, creating an audible “pop” sound. Keep pumping until the tire reaches the recommended pressure.
3. Check that the tire bead is evenly seated on both sides of the rim. If the bead is not seated properly, deflate the tire slightly and adjust it before re-inflating.

Final Adjustments and Checking for Leaks

Once the tire bead is seated, it’s important to check for any air leaks that may compromise the tubeless setup.

1. Inspect the tire carefully for any hissing sounds or visible leaks. If you notice any issues, you can rotate the tire to allow the sealant to spread evenly across the rim and seal any minor holes.
2. If the tire is still leaking, you may need to add more sealant or check for any gaps in the rim tape.

Troubleshooting Common Set-Up Issues

Tire Not Inflating Properly

If the tire is not inflating properly, it could be due to the following reasons:

• The tire bead is not seated properly. Deflate the tire and ensure the bead is positioned correctly on both sides of the rim.
• The valve stem is not tight enough. Ensure the valve stem is securely attached to the rim, and there is no air escaping around the valve.
• Insufficient sealant. If you suspect a leak, add more sealant through the valve stem.

Leaking Sealant

If sealant is leaking from the sidewall or bead area, it may be due to an improper bead seating or insufficient sealant. In this case:

• Deflate the tire slightly, rotate it, and bounce it gently to help the sealant coat the inner sidewalls of the tire.
• Check for any visible gaps in the rim tape and reapply if necessary.

Customizing and Optimizing Your EN355 Hydra Tubeless Setup

To optimize the performance of your EN355 Hydra wheels with tubeless tires, consider the following tips:

1. Tire Pressure: Running lower tire pressure can improve comfort and traction, but it’s essential to avoid going too low, as this may cause rim damage. Test different pressures to find the optimal balance.
2. Sealant Maintenance: Over time, tubeless sealant can dry out. Check your tire regularly and top up the sealant if necessary.
3. Tire Selection: Choose tires that are designed for tubeless use and are compatible with the EN355 Hydra rims. Tires with a strong, puncture-resistant casing work best.

Compatibility with Other Drivetrain Components

The EN355 Hydra wheels are compatible with most modern road bike drivetrains, including Shimano, SRAM, and Campagnolo systems. Ensure that your wheels and tires match the specifications of your drivetrain, including gear ratios and brake compatibility.

Conclusion

Setting up tubeless tires on your EN355 Hydra wheels can provide significant benefits in terms of performance, comfort, and durability. By following these steps for installation, maintenance, and troubleshooting, you can achieve a reliable, high-performance tubeless setup. Regular checks and adjustments will ensure that your tubeless system continues to perform optimally, allowing you to enjoy your rides without worrying about punctures or air loss.
