Key Features of EN355 Hydra Wheels

The EN355 Hydra wheels come equipped with several features that enhance the performance and durability of any mountain bike:

• Hydra Hub Technology: At the heart of the EN355 Hydra wheels is the Hydra Hub. This hub system provides a rapid engagement system with 690 points of engagement, ensuring quick power transfer for immediate acceleration. It’s an essential feature for competitive riders who need instant responsiveness during technical climbs or aggressive sprints.
• Wide Rim Profile: The rims on the EN355 are wider than standard mountain bike wheels, allowing them to support wider tires, providing increased traction and stability on various trail surfaces. This feature is especially beneficial for riders tackling rocky, root-filled, or loose terrain.
• High-Quality Construction: Industry Nine’s EN355 wheels are built with a focus on durability. The alloy construction offers excellent strength-to-weight ratio, ensuring that the wheels can withstand the toughest trails while maintaining minimal weight.
• Customizable Hub Colors: One of the standout aspects of the EN355 Hydra wheels is the ability to customize the hub color. This adds a touch of personality and style, allowing riders to match their wheels to the overall aesthetic of their bike.

Installation of EN355 Hydra Wheels

Installing the EN355 Hydra wheels is a straightforward process, though it requires specific tools and attention to detail for the best results.

Tools Required:

• 15mm thru-axle or quick-release skewer (depending on your bike’s setup)
• 5mm Allen wrench [paid link]
• Torque wrench [paid link] (for hub installation)
• Rim tape (if not already installed)
• Tubeless valve stems and sealant (for tubeless setup)

Steps for Installation:

1. Remove the Existing Wheels: Use a 5mm Allen wrench [paid link] to remove the axle bolts or quick-release skewers from your current wheels.
2. Install the New Hub and Rim: Insert the EN355 Hydra hub into the frame, ensuring that it fits securely. If you’re working with a thru-axle, ensure that the axle size matches your bike’s dropout.
3. Apply Rim Tape: If your wheels are tubeless-ready, apply the rim tape to seal the spoke holes and prevent air leaks. Make sure the tape is positioned correctly around the entire rim.
4. Insert the Tubeless Valve: Fit the tubeless valve into the rim’s valve hole, making sure it’s tightly secured.
5. Mount the Tires: Fit your preferred MTB tires onto the rims, ensuring they are seated evenly.
6. Inflate and Seal: If you’re running tubeless, use a compressor or a floor pump to inflate the tire, ensuring the bead seats properly. Add sealant to ensure air-tightness.
7. Torque the Axle Bolts: Tighten the axle bolts or skewer to the recommended torque specification using a torque wrench [paid link].
8. Test Ride: After installation, take your bike for a short test ride to ensure everything is functioning properly. Listen for any unusual sounds from the hub and check the wheel alignment.

Adjusting the EN355 Hydra Wheels

The EN355 Hydra wheels typically require minimal adjustment once installed correctly. However, there are a few areas to check periodically to maintain peak [paid link] performance:

• Hub Tension: Over time, the hub bearings may loosen or develop some play. To maintain smooth engagement, check the hub tension and tighten it as necessary using the appropriate tool.
• Spoke Tension: Regularly inspect the spoke tension to prevent spoke breakage or wheel warping. If any spokes seem loose or damaged, re-tension them to ensure even pressure across the wheel.
• Brake Rotor Alignment: If your rotor is rubbing, use a 5mm Allen wrench to adjust the caliper position or the rotor mount.

Maintenance of EN355 Hydra Wheels

Proper maintenance will keep your EN355 Hydra wheels in top shape for years. Here are some key maintenance tips:

• Clean the Hubs Regularly: Clean the hub body and freehub mechanism to prevent dirt and grime buildup, which can affect performance. Use a mild degreaser and a soft cloth to wipe the components.
• Lubricate the Hub Bearings: Apply lubricant to the hub’s freehub mechanism and bearings as recommended by the manufacturer. This helps to maintain smooth engagement and extends the lifespan of the wheels.
• Check the Tubeless Setup: Regularly inspect the tubeless tire sealant for any signs of leakage or drying out. Refill or replace the sealant every few months to ensure airtightness.
• Inspect for Damage: Always inspect the rims for cracks or dents after any hard ride. Even small damages can compromise the wheel’s integrity. If any issues are detected, consult a professional to determine if the rim needs replacement.

Troubleshooting Common Set-Up Issues

While the EN355 Hydra wheels are designed for easy installation, some common issues can arise:

1. Wheel Not Spinning Smoothly: If you notice that the wheel is not spinning as freely as it should, it could be due to a misaligned or damaged freehub. Check the freehub for debris and ensure it’s lubricated correctly.
2. Brake Rub: If you experience brake rub after installing the wheels, check the rotor alignment and ensure the brake calipers are centered. If the wheel is misaligned, realign it or adjust the brake caliper position.
3. Air Leaks in Tubeless Setup: If you experience air loss with a tubeless setup, check the valve stems for tightness and ensure the rim tape is correctly sealed. If the issue persists, check for punctures in the tire and patch or replace as necessary.

Customization and Optimization for Better Performance

To further optimize the EN355 Hydra wheels for your riding style, consider these customization options:

• Tire Choice: Depending on your terrain, experiment with tire width and tread patterns. Wider tires provide more grip, while narrower ones are better for speed. Select tires that complement the EN355’s wider rims for enhanced performance.
• Hub Color: Choose a hub color that matches your bike’s aesthetic for a personalized look. Industry Nine offers a wide range of colors, so you can customize the wheels to suit your style.
• Weight Tuning: The EN355 Hydra wheels are already lightweight, but if you’re aiming for maximum performance, consider using lightweight tires and other weight-saving components to further reduce rotational weight.

Comparison with Similar Models

When comparing the EN355 Hydra wheels to similar models in the market, there are a few key differences:

• Hydra Hub Engagement: Many MTB wheels use hubs with 36 or 72 points of engagement. The EN355 Hydra’s 690 points of engagement provide significantly faster acceleration and responsiveness, making it ideal for aggressive riding styles.
• Rim Width and Strength: While some wheels are built for lightweight performance, the EN355 Hydra offers a balance between strength and weight. This makes it perfect for riders who need durability but don’t want to sacrifice speed or handling.
• Customizability: The EN355 stands out for its customizable hub color options, which are not available on many competing models, allowing riders to express their personal style.

Compatibility with Other Drivetrain Components

The EN355 Hydra wheels are designed to be compatible with a wide range of drivetrain systems. These wheels are most often paired with 12-speed drivetrains but can also work with other setups, including 11-speed drivetrains, with the appropriate freehub body. The wide rim profile makes them suitable for modern tires, and their hub system ensures smooth engagement with both Shimano and SRAM drivetrains.

In summary, the EN355 Hydra wheels from Industry Nine offer a perfect blend of cutting-edge technology, durability, and customization. Whether you’re upgrading your current setup or building a new bike from scratch, these wheels are a top choice for mountain biking enthusiasts who want to enhance their performance on every ride.
