This guide will explore the installation, maintenance, and optimization of the EN355 Hydra [paid link] wheels, along with troubleshooting common issues and comparing them to other models to help riders make an informed decision. Additionally, we’ll examine how these wheels integrate with various drivetrain components and highlight their potential for customizations.

Tools Required

  • Torque wrench [paid link]
  • 5mm hex wrench
  • Spoke wrench
  • Tubeless tire kit
  • Rim tape (if not pre-installed)
  • Valve stems
  • Sealant
  • Tire levers
  • Hub grease
  • 15mm or 20mm thru-axle tool (depending on your fork/frame compatibility)
  • Hub oil (for periodic maintenance)

Installation of EN355 Hydra Wheels

Installing the Industry Nine EN355 Hydra wheels is a relatively straightforward process, but it requires attention to detail to ensure proper setup and performance.

  1. Remove the Old Wheels: Use a 5mm hex wrench to remove the axle bolts and take off the existing wheels from the bike. If you’re switching out your current wheels for the EN355 Hydra, make sure that the new wheels’ hub and axle type are compatible with your frame and fork.
  2. Install the Front Wheel: Begin by inserting the front wheel into the fork dropouts. Use the appropriate thru-axle or quick-release skewer, ensuring the wheel is centered and locked in place.
  3. Install the Rear Wheel: For the rear wheel, align the cassette with the derailleur. Insert the wheel into the dropouts, ensuring it sits flush. Tighten the axle with a torque wrench [paid link] to the manufacturer’s recommended settings.
  4. Tubeless Setup (Optional): If you’re setting up the wheels as tubeless, install the rim tape, valve stems, and sealant before mounting the tires. Carefully mount the tire using tire levers, ensuring it’s seated properly before inflating. Use a high-pressure pump to seat the bead, and ensure there are no air leaks.
  5. Final Checks: Spin the wheels to ensure they are running true, without any wobble. Check brake pad clearance, ensuring there is no rubbing on the rims or rotor (if disc brakes are used).

Adjusting and Maintaining EN355 Hydra Wheels

The EN355 Hydra wheels are built for performance and durability, but like any high-performance component, they require regular maintenance to maintain optimal performance.

Hub Maintenance

  1. Hydra Hub Engagement: The EN355 wheels feature Industry Nine’s Hydra hub, which uses a 690-point engagement system. This system provides quick engagement, reducing lag during acceleration. If you experience any issues with engagement, it’s often related to the freehub mechanism or inadequate lubrication. To resolve this, disassemble the hub, clean out old grease, and apply a fresh layer of high-quality hub grease.
  2. Bearing Care: The EN355 Hydra hubs use sealed bearings that should last a long time under normal conditions. However, if you notice any roughness or play in the hubs, it’s a good idea to inspect and replace the bearings. Regularly check for dirt ingress and ensure the hub is fully sealed.

Spoke Tension and Wheel Truing

  1. Check Spoke Tension: Over time, spoke tension can change. Use a spoke tension meter or a spoke wrench to check and adjust the tension if needed. Uneven tension can lead to wheel misalignment and loss of performance.
  2. Truing the Wheels: If the wheels become untrue due to impact or normal wear, you can true them using a spoke wrench. Adjust the spokes to eliminate any wobble. Keep in mind that it’s often best to seek professional help for extensive truing if you’re not experienced.

Tire Maintenance

To maintain the tubeless setup, inspect your tires regularly for punctures or wear. Refill the sealant every 3-6 months or sooner if you notice the tires are not holding air properly.

Troubleshooting Common EN355 Hydra Wheel Issues

1. Poor Engagement or Noisy Hub

  • Cause: The Hydra hub’s rapid engagement mechanism may become noisy or fail to engage properly if the pawls are not lubricated or are dirty.
  • Solution: Disassemble the hub, clean the pawls, and re-lubricate them with the manufacturer’s recommended grease. Ensure the freehub body is free of debris.

2. Wheel Not Rolling Smoothly

  • Cause: Resistance in the bearings or a poorly seated tire can cause the wheel to feel sluggish.
  • Solution: Check the bearings for roughness or damage, and replace them if necessary. Inspect the tire bead and ensure the tire is properly inflated and seated.

3. Spokes Going Out of Tension

  • Cause: Over time, spokes can lose tension, leading to a wobbling wheel.
  • Solution: Check spoke tension regularly using a spoke wrench and adjust accordingly. Retighten any loose spokes and check for wheel trueness.

Customization and Optimization for Better Performance

1. Adjusting Spoke Tension for Weight and Riding Style

  • Customizing spoke tension is a key optimization for riders who want to tune their wheels for specific conditions. For aggressive riders or those riding on rough terrain, a higher spoke tension may offer added strength. For lighter riders or smoother roads, a lower spoke tension may improve comfort and reduce weight.

2. Tire Choice for Performance

  • The EN355 wheels are compatible with a range of tire options. Depending on the terrain you ride on, you can optimize your tire choice to balance speed, traction, and durability. Choose wider tires for comfort and traction on rough roads, or go for narrower tires for greater speed on smoother surfaces.

3. Hub and Freehub Options

  • The EN355 Hydra wheels are available with different hub configurations. For maximum performance, consider pairing the wheels with a compatible drivetrain and selecting a hub option that fits your riding style, whether it’s for climbing, descending, or sprinting.

Comparing EN355 Hydra Wheels to Other Models

When considering an upgrade to the EN355 Hydra wheels, it’s essential to compare them to other options on the market, such as the DT Swiss 240s or the Chris King R45 hubs. Here’s how the EN355 Hydra stands out:

  • Engagement System: The Hydra hub has one of the quickest engagement systems, offering a 0.52° engagement angle. In comparison, the DT Swiss 240s has a 10° engagement, which is slower.
  • Weight: The EN355 wheels are slightly heavier than some high-end options but offer enhanced durability and stiffness, making them ideal for aggressive riders.
  • Price: While the EN355 wheels are premium-priced, the advanced engagement and reliability make them a worthy investment for riders looking for high performance and longevity.

Compatibility with Other Drivetrain Components

The EN355 Hydra wheels are highly compatible with a wide range of drivetrains, from SRAM to Shimano, due to their interchangeable freehub bodies. Ensure that the freehub body you select matches your drivetrain type. For example, SRAM XD drivers are compatible with SRAM’s 12-speed cassettes, while Shimano freehub bodies support 11-speed and 12-speed Shimano cassettes.

When installing the EN355 Hydra wheels, make sure that your rear derailleur, chain, and cassette are also compatible with the number of gears you intend to run. Proper drivetrain compatibility ensures smooth shifting and optimal performance.
