Replacing the spokes on your EN355 Hydra [paid link] wheels from Industry Nine is an essential part of bike maintenance that helps ensure your wheels remain true, strong, and reliable. This task requires some skill, patience, and the right tools, but with careful attention, it can be completed successfully. This guide covers the step-by-step process for replacing spokes on your EN355 Hydra [paid link] wheels, including essential tools, troubleshooting tips, and advice on customization for better performance.

Tools Required

• Spoke Wrench: To adjust and tighten the spoke nipples.
• Nipple Driver: For easier installation of new spoke nipples.
• 16mm or 15mm Spoke Wrench: Depending on the size of the spokes.
• Philips or Flat Head Screwdriver: To remove the wheel hub cover if necessary.
• Rim Tape: To protect the inner rim from damage caused by spoke nipples.
• Truing Stand: For ensuring the wheel is perfectly straight after replacing the spokes.
• Tension Meter: To check the spoke tension and ensure uniformity across all spokes.
• Replacement Spokes: Ensure you have the correct size and spoke type for your EN355 Hydra wheels.

Preparation and Removal of the Damaged Spokes

Before you begin the spoke replacement process, ensure that your bike is in a safe and stable position, preferably in a repair stand. The following steps outline how to remove the damaged spokes.

1. Inspect the Wheel: Check for any broken or severely bent spokes. Identify which spokes need to be replaced, and note their positions on the wheel. If the wheel is severely out of true, you may want to mark the positions of the broken spokes to guide the replacement process.
2. Remove the Wheel: If the wheel is still on the bike, remove it carefully using the appropriate quick-release lever or axle tool. Ensure you set the wheel down on a clean surface to avoid damaging the rim or spokes.
3. Loosen the Tension: Before removing any spokes, reduce the overall spoke tension by loosening all the spoke nipples slightly. This prevents unnecessary stress on the remaining spokes during the removal process. Using a spoke wrench, carefully loosen the nipple on the broken spoke, turning counterclockwise.
4. Remove the Damaged Spoke: After loosening the nipple, carefully remove the spoke from the hub and rim. Depending on the design, the spoke may have a straight or J-bend at one end. Remove it gently to avoid damage to the surrounding spokes.
5. Inspect the Hub and Rim: Once the damaged spoke is removed, inspect the hub and rim for any potential issues, such as cracks or damage that could affect the installation of the new spokes. Clean the area where the spoke was installed, and ensure there is no debris or corrosion.

Installing the New Spokes

With the damaged spokes removed, it’s time to install the new spokes onto your EN355 Hydra wheel.

1. Prepare the New Spokes: Take the replacement spokes and ensure they match the specifications of the original spokes, including length and type. For EN355 Hydra wheels, it’s crucial that the spokes are the correct size to ensure proper wheel tension and performance.
2. Position the Spokes: Insert the new spokes through the appropriate holes in the hub. Begin by threading the spoke through the hub from the inside, ensuring that the spoke’s J-bend or straight end aligns with the rim holes properly. Position the spoke so that it enters the rim hole from the inside, and the J-bend faces the outside of the wheel.
3. Install the Nipples: Thread a nipple onto the end of the spoke. For easier installation, use a nipple driver. The nipple should be placed carefully into the rim’s spoke hole, ensuring it’s positioned correctly to avoid cross-threading.
4. Preliminary Tensioning: Tighten the nipple just enough to hold the spoke in place, but avoid over-tightening at this stage. This is to ensure that the spoke remains in position while the other spokes are installed.
5. Repeat for All Spokes: Continue this process for all the damaged spokes, ensuring that each spoke is installed correctly. Pay attention to the spoke pattern as per the wheel’s design to ensure consistency. For the EN355 Hydra, this typically follows a 3-cross lacing pattern (or another specified pattern for the wheel).

Truing and Tensioning the Wheel

Once all new spokes are installed, the next step is to true the wheel and ensure the spokes are evenly tensioned.

1. Mount the Wheel in a Truing Stand: Place the wheel on a truing stand. Spin the wheel slowly to check for any lateral or radial deviations. Make adjustments to the spoke tension as necessary to correct any misalignment.
2. Adjust Spoke Tension: Using a spoke wrench, adjust the tension of each spoke in small increments. Tighten or loosen the spoke nipples evenly to ensure uniform tension across all spokes. A tension meter can help you measure the exact spoke tension for a more precise adjustment.
3. Check for Trueness: As you adjust the tension, periodically check the wheel for trueness by spinning it in the truing stand. If the wheel wobbles to the side, adjust the spokes that are too tight or too loose in the areas where the wheel is deviating.
4. Final Tightening: Once the wheel is true and all spokes are at an even tension, perform a final tightening on all nipples to ensure they are securely fastened. This step is critical to ensure the spokes will remain tight during use.
5. Test Ride: Before fully reassembling the bike, take the wheel out for a brief test ride to ensure that everything feels secure and the wheel is functioning smoothly. Pay attention to any unusual noises or sensations that could indicate that the spokes are not properly tensioned.

Troubleshooting Common Set-Up Issues

While replacing spokes on the EN355 Hydra wheels, you might encounter some common issues. Here are some troubleshooting tips:

• Wheel Wobble: If your wheel is still wobbly after replacing the spokes, it may be that the spoke tension is uneven. Recheck the tension on each spoke, making small adjustments as necessary.
• Loose Nipples: Over time, spoke nipples may loosen. After replacing spokes, it’s a good practice to check the nipples after a few rides to ensure they are tight and the wheel remains true.
• Spoke Failure: If new spokes break shortly after replacement, it could be due to incorrect spoke length or poor tensioning. Ensure the spokes are the right size for the EN355 Hydra wheels and that the tension is evenly distributed.

Customization and Optimization for Better Performance

To get the most out of your EN355 Hydra wheels after replacing the spokes, consider the following tips:

1. Upgrade to Stronger Spokes: For heavier riders or more aggressive riding styles, you might want to upgrade to stronger spokes, such as double-butted or straight-gauge spokes. This can improve the durability of your wheels.
2. Carbon vs. Aluminum Nipples: While aluminum nipples are standard for most wheels, carbon fiber nipples can help reduce weight. However, they can be more difficult to adjust and maintain.
3. Adjusting Spoke Tension for Performance: Experimenting with spoke tension can have an impact on wheel stiffness and ride quality. Generally, stiffer wheels provide better performance but less comfort, while more compliant wheels offer better comfort at the cost of some stiffness.
4. Periodic Maintenance: Regularly check spoke tension and wheel trueness as part of your bike maintenance routine. Keeping the spokes in good condition will help prolong the life of your EN355 Hydra wheels.

Conclusion

Replacing spokes on your EN355 Hydra wheels from Industry Nine is a task that requires precision, the right tools, and an understanding of wheel mechanics. By following the proper steps for spoke removal, installation, and wheel truing, you can ensure your wheels remain durable and perform optimally. With regular maintenance and attention to spoke tension, your wheels will continue to provide the performance and reliability that you need on your rides.
