Additionally, we will compare it with other similar models to help you make an informed decision about your gravel bike setup.

Installation of the Ekar WRL Rear Derailleur

The installation of the Ekar WRL Rear Derailleur is a straightforward process, but it requires attention to detail for optimal shifting performance. Before starting, ensure that your gravel bike frame is compatible with the Ekar drivetrain system.

Tools Required:

  • 5mm Allen key
  • 2.5mm Allen key
  • Torque wrench
  • Chain tool
  • Shimano or Campagnolo cassette tool (depending on your bike’s cassette type)
  • Ekar derailleur hanger alignment tool

Installation Steps:

  1. Remove the existing derailleur: Begin by removing the old rear derailleur. Use a 5mm Allen key to detach the derailleur from the derailleur hanger.
  2. Install the derailleur hanger: Ensure the derailleur hanger is aligned properly using an alignment tool. This step is crucial for precise shifting and avoiding any misalignment issues.
  3. Attach the Ekar WRL derailleur: Using the 5mm Allen key, securely attach the derailleur to the derailleur hanger. Tighten the bolt to the recommended torque setting (usually around 8-10 Nm).
  4. Install the chain: Feed the chain through the derailleur, ensuring it passes correctly over the jockey wheels. Use a chain tool to connect the chain ends if needed.
  5. Set up the derailleur for proper indexing: Adjust the derailleur position and limit screws for smooth, reliable shifts across all cogs.
  6. Test the system: Once installed, manually shift through all gears to ensure proper movement. Fine-tune the adjustments for smooth performance.

Adjustment and Fine-Tuning

The Ekar WRL Rear Derailleur is designed to provide reliable, precise shifting performance in tough gravel environments. However, adjustments may be needed over time due to wear or changes in riding conditions.

Indexing the Gears:

  1. Adjust the barrel adjuster: If shifting is sluggish or skips gears, begin by adjusting the barrel adjuster on the derailleur or shifter. Turning it counterclockwise will tighten the cable and shift the derailleur to a higher gear, while turning it clockwise loosens the cable and shifts to a lower gear.
  2. Limit screws: Ensure that the high and low limit screws are correctly set. The high screw controls the position of the derailleur on the smallest cog, while the low screw controls the largest cog. Misadjustment can lead to poor shifting performance or the chain falling off.
  3. Jockey wheels and chain: Keep an eye on the jockey wheels. If they become worn or damaged, replace them to ensure smooth chain movement and prevent skipping.

B-Tension Adjustment:

The Ekar WRL uses a unique B-tension screw design to adjust the derailleur’s angle, allowing for optimized clearance between the jockey wheels and cassette. This is especially crucial when running larger cogs. Adjust the B-tension screw by tightening or loosening it to fine-tune the derailleur’s positioning for perfect chain movement.

Maintenance of the Ekar WRL Rear Derailleur

Regular maintenance is essential for ensuring that the Ekar WRL Rear Derailleur continues to perform at its best, even in harsh gravel riding conditions.

Regular Cleaning:

  • Keep the derailleur clean: Gravel rides can expose the derailleur to dust, dirt, and debris. Clean the derailleur regularly with a soft brush and degreaser to maintain smooth shifting performance.
  • Lubricate the jockey wheels: Apply a small amount of lubricant to the jockey wheels to prevent wear and ensure smooth movement. Avoid excessive lubrication, as it can attract dirt.

Chain and Cable Maintenance:

  • Inspect the chain regularly: Check for chain wear and replace it as needed. A worn chain can negatively affect shifting performance and damage the derailleur.
  • Cable tension check: Periodically check cable tension to prevent slack or overstretching, both of which can hinder shifting accuracy.

Troubleshooting Common Issues

Despite its robust design, the Ekar WRL Rear Derailleur may experience common issues due to wear or setup mistakes. Here are some troubleshooting tips for resolving common problems.

Skipping Gears:

  • Cause: Skipping gears typically occurs when the derailleur is out of alignment or the chain is worn.
  • Solution: Recheck the derailleur hanger alignment and adjust the limit screws. If the chain is worn, replace it. Ensure that the derailleur is properly tensioned for optimal shifting.

Slow or Unresponsive Shifting:

  • Cause: This could be caused by improper indexing or a worn derailleur cable.
  • Solution: Adjust the barrel adjuster to fine-tune the indexing. If the derailleur cable is frayed or stretched, replace it for smooth shifting.

Chain Drop:

  • Cause: A dropped chain can occur if the derailleur limit screws are not correctly set or if there is insufficient tension on the chain.
  • Solution: Check the limit screws and make sure they are correctly adjusted. Tighten the chain if it has become too loose or replace it if it is excessively worn.

Customization and Optimization for Better Performance

The Ekar WRL Rear Derailleur offers several options for customization to enhance your gravel riding experience.

Changing the Cog Setup:

  • Customize your gear ratios: The Ekar system is compatible with a wide range of cogs. Depending on your terrain, you can swap to larger or smaller cogs to optimize your gear range. A larger cog setup is ideal for steep, technical gravel climbs, while a smaller cog setup suits flat terrain for faster riding.

Shifting Performance:

  • Upgrade your shifters: Pairing the Ekar WRL Rear Derailleur with Campagnolo’s Ekar 13-speed shifters ensures the best shifting performance. Consider using upgraded cables and housing to reduce friction, further enhancing shifting speed and precision.

Comparison with Similar Models

The Ekar WRL Rear Derailleur is part of Campagnolo’s revolutionary gravel drivetrain system, but how does it compare to other rear derailleurs available for gravel bikes?

Shimano GRX Rear Derailleur:

  • The Shimano GRX is a popular choice for gravel riders, offering solid performance. However, the Ekar WRL Rear Derailleur offers a more precise 13-speed system compared to Shimano’s 11-speed GRX, making it better suited for riders looking for a wider range of gears.
  • Campagnolo’s Ekar WRL system is also lighter and features an innovative derailleur design, which minimizes drag and provides smoother operation on rough terrain.

SRAM Force eTap AXS:

  • SRAM’s Force eTap AXS offers electronic shifting, which may appeal to riders looking for a more hands-off, precise shifting experience. However, the Ekar WRL’s mechanical system offers a more traditional feel with less complexity and fewer potential points of failure.
  • While both models offer excellent gravel performance, the Ekar WRL is known for its exceptional durability, making it a better choice for harsh gravel conditions.

Compatibility with Other Drivetrain Components

The Ekar WRL Rear Derailleur is designed to work seamlessly within the Campagnolo Ekar 13-speed drivetrain system. It is specifically optimized for gravel riding, ensuring compatibility with Campagnolo’s 13-speed cassettes and shifters.

Compatibility Notes:

  • Shifters: The Ekar WRL is only compatible with Campagnolo Ekar 13-speed shifters. Ensure that your bike is equipped with these shifters for optimal performance.
  • Cassettes: Only Campagnolo’s Ekar 13-speed cassettes are compatible with the Ekar WRL Rear Derailleur. While you can adjust the cog sizes within the range, compatibility with non-Campagnolo cassettes is not guaranteed.

The system’s compatibility ensures that all components work harmoniously, delivering smooth shifting and reliable performance on gravel terrain.
