Installation of the Ekar WRL Rear Derailleur

Installing the Ekar WRL Rear Derailleur is a straightforward process that requires some basic tools and attention to detail. Follow these steps to properly install the derailleur onto your gravel bike.

  1. Remove the Old Derailleur: If you are upgrading from a previous derailleur system, begin by using the appropriate tools to remove the old derailleur. This may involve removing the chain and unscrewing the derailleur hanger.
  2. Mount the Derailleur Hanger: Before installing the new derailleur, make sure the derailleur hanger is aligned correctly. Use a derailleur hanger alignment tool if needed to ensure that the hanger is straight.
  3. Attach the Ekar WRL Derailleur: Secure the derailleur to the derailleur hanger using a 5mm Allen wrench. Tighten it to the recommended torque specification (usually around 8-10Nm).
  4. Install the Chain: Thread the chain through the derailleur, ensuring it passes through the jockey wheels properly. You may need to use a chain tool to size the chain correctly if it’s a new installation.
  5. Connect the Shifting Cable: The Ekar WRL derailleur operates with a specific cable tension. Use a 3mm Allen wrench to attach the derailleur to the shift cable. Ensure that the cable is routed cleanly and has a slight amount of slack to allow for smooth shifting.
  6. Install the Cassette: If not already done, install the Ekar-specific cassette on the rear wheel, ensuring it is fully seated and tightened using the appropriate lockring tool.
  7. Final Checks: Double-check all bolts and the derailleur alignment before proceeding to the adjustment phase.

Adjustment of the Ekar WRL Rear Derailleur

Proper adjustment of the Ekar WRL Rear Derailleur ensures smooth shifting performance and optimal gear range. The Ekar system features a 1×13 drivetrain, so precise adjustment is critical for reliability, especially on gravel and mixed-terrain rides.

  1. Set the B-Screw: The B-screw controls the distance between the derailleur and the cassette. Adjust the B-screw to ensure there is a small gap (about 5-6mm) between the derailleur and the largest cog of the cassette.
  2. Adjust the Limit Screws: Use a 3mm Allen wrench to adjust the limit screws on the derailleur. The limit screws prevent the derailleur from shifting past the first and last cogs. Ensure the derailleur doesn’t overshoot the largest or smallest cog, which can lead to chain slippage or damage.
  3. Fine-Tune the Cable Tension: Shift into the smallest cog and adjust the barrel adjuster at the derailleur or shifter to achieve the correct cable tension. The chain should move freely across all cogs without hesitation or jumping.
  4. Test Shifting: Shift through the entire range of gears to ensure smooth transitions. Fine-tune the cable tension and B-screw if necessary, repeating until the shifting is crisp and precise across all cogs.
  5. Check for Chainline Alignment: Ensure that the chainline is straight and consistent across all gears. A misaligned chainline can cause poor shifting performance and excessive wear.

Maintenance of the Ekar WRL Rear Derailleur

Maintaining the Ekar WRL Rear Derailleur is essential for keeping your gravel bike in top condition, especially when subjected to the harsh conditions often encountered on gravel roads. Regular maintenance will help prevent wear, corrosion, and ensure smooth operation.

  1. Regular Cleaning: After each ride, particularly on muddy or wet terrain, thoroughly clean the derailleur using a soft brush and degreaser. Avoid using high-pressure water to clean the derailleur, as this can force dirt into sensitive areas.
  2. Lubrication: Periodically apply lubricant to the derailleur’s moving parts, including the jockey wheels and pivot points. Use a lightweight lubricant to avoid attracting dirt and grit [paid link].
  3. Check the Chain: The Ekar system’s 13-speed chain needs regular inspection for wear. A worn chain can affect shifting performance and cause premature wear to the cassette and derailleur. Use a chain checker tool to measure chain stretch and replace it when necessary.
  4. Inspect the Derailleur Hanger: The derailleur hanger is susceptible to bending from impacts during gravel riding. Regularly inspect the hanger and realign it if necessary. If the hanger is bent beyond repair, replace it immediately to prevent damage to the derailleur.
  5. Cable Tension: Over time, shift cables can stretch, affecting performance. Regularly check the cable tension, especially after extended rides or rough conditions, and adjust it to maintain optimal shifting accuracy.

Troubleshooting Common Set-Up Issues

Even with high-quality components like the Campagnolo Ekar WRL Rear Derailleur, riders may encounter a few common set-up issues. Here’s how to address them:

    • Solution: Check cable tension and clean the derailleur. Ensure the cable is moving smoothly and lubricate the jockey wheels.
  2. Skipping or Dropping Gears:
    • Possible Cause: Worn chain or cassette, or improper derailleur alignment.
    • Solution: Inspect the chain and cassette for wear. Realign the derailleur hanger if necessary and re-check the limit screws.
  3. Chain Rub on Larger Cogs:
    • Possible Cause: Improper B-screw adjustment or misalignment of the derailleur.
    • Solution: Adjust the B-screw to increase the distance between the derailleur and the largest cog. Ensure the derailleur is properly aligned.
  4. Chain Getting Stuck in the Largest Cog:
    • Possible Cause: Incorrect limit screw adjustment or excessive cable tension.
    • Solution: Adjust the high limit screw to prevent the derailleur from over-shifting into the largest cog.
