Tools Required

Before you begin working on your Campagnolo Ekar 13 RD rear derailleur, make sure you have the following tools on hand:

  • 5mm Allen wrench
  • 3mm Allen wrench
  • Torx T25 wrench
  • Chain checker tool
  • Cable cutter
  • Torque wrench (with correct torque setting)
  • Grease
  • Lubricant
  • Chain whip tool
  • Cassette tool
  • Chain tool

Installation of the Ekar 13 RD Rear Derailleur

Installing the Campagnolo Ekar 13 RD is straightforward if you follow the correct steps. Whether you’re installing a new derailleur or replacing an old one, it’s important to ensure that everything is installed properly for optimal performance.

Step-by-Step Guide for Installation

  1. Remove the old derailleur: If you’re replacing an old derailleur, use a 5mm Allen wrench to remove the mounting bolt that holds the derailleur in place.
  2. Prepare the derailleur hanger: Before mounting the new derailleur, make sure the derailleur hanger is straight. A bent hanger can lead to poor shifting performance.
  3. Mount the Ekar 13 RD: Position the derailleur on the derailleur hanger and secure it with the mounting bolt. Tighten it with a 5mm Allen wrench.
  4. Install the chain: Pass the chain through the jockey wheels of the derailleur, ensuring that it runs smoothly and does not interfere with the derailleur movement. Use a chain tool to size and join the chain if necessary.
  5. Attach the derailleur to the cable: Slide the derailleur cable through the cable anchor bolt on the derailleur. Tighten the bolt with a 3mm Allen wrench to secure the cable.
  6. Set up the shifting mechanism: Install the shift cable to the shifter, making sure the cable is tensioned properly before tightening the anchor bolt.
  7. Install the cassette: If you are replacing the cassette as well, use a chain whip tool and cassette tool to remove the old cassette and install the new one.

After installation, check the alignment of the derailleur and test the shifting performance.

Adjustment of the Ekar 13 RD Rear Derailleur

Fine-tuning the Campagnolo Ekar 13 RD rear derailleur is crucial for achieving smooth, accurate shifts. The Ekar 13 RD is equipped with both high and low limit screws, as well as barrel adjusters, which allow for precise fine-tuning.

Step-by-Step Guide for Adjusting the Derailleur

  1. Set the high and low limit screws:
    • High limit screw: Adjust the high limit screw to prevent the derailleur from shifting the chain off the smallest cog. Set it so that the jockey wheel is aligned with the smallest cog.
    • Low limit screw: Adjust the low limit screw to stop the derailleur from shifting the chain off the largest cog. Set it so the jockey wheel aligns with the largest cog.
  2. Fine-tune the derailleur position: Use the barrel adjuster to make small adjustments in cable tension. Turn the barrel adjuster counterclockwise to increase tension and clockwise to decrease tension. This will help in fine-tuning the shifting accuracy.
  3. Check shifting performance: After making the adjustments, test the shifting through all gears. Ensure that the derailleur moves smoothly across the cassette and that there is no skipping or hesitation.

If the derailleur is still misbehaving, recheck the limit screws and cable tension.

Maintenance of the Ekar 13 RD Rear Derailleur

Regular maintenance ensures the longevity and optimal performance of your Campagnolo Ekar 13 RD rear derailleur. Dirt, moisture, and wear can degrade performance, so it’s essential to clean, lubricate, and inspect your derailleur regularly.

Cleaning and Lubricating

  • Clean the derailleur: Use a mild degreaser and a soft brush to clean the derailleur, ensuring that all dirt and grime are removed. Pay close attention to the jockey wheels and pivot points, as these areas tend to accumulate debris.
  • Lubricate moving parts: Apply a light lubricant to the derailleur pivot points and jockey wheels. Be careful not to over-lubricate, as excess oil can attract dirt and debris.
  • Inspect the derailleur: Regularly inspect the derailleur for any signs of wear, including cracks, bent parts, or rust. Ensure the jockey wheels spin freely and are not clogged with dirt or chain lubricant.

Chain and Cassette Maintenance

The condition of your chain and cassette directly affects the performance of the rear derailleur. Make sure to clean and lubricate the chain regularly and check the cassette for wear. A worn-out chain or cassette can lead to poor shifting and increased strain on the derailleur.

Troubleshooting Common Set-Up Issues

Despite the precision engineering of the Campagnolo Ekar 13 RD, common issues can still arise. Here are some troubleshooting tips for resolving common problems.

Problem: Shifting Is Slow or Hesitant

  • Cause: This could be caused by poor cable tension or dirty components.
  • Solution: Check the cable tension and clean the derailleur. Adjust the barrel adjuster to fine-tune cable tension. Ensure that the derailleur moves freely without obstruction.

Problem: Chain Drops Off the Cassette

  • Cause: Misaligned derailleur or improperly adjusted limit screws.
  • Solution: Double-check the limit screw settings. Ensure that the derailleur hanger is straight and the derailleur is positioned properly.

Problem: Chain Skipping Between Gears

  • Cause: Worn cassette or chain, improper chain lubrication, or incorrect derailleur alignment.
  • Solution: Inspect the chain and cassette for wear and replace them if necessary. Ensure proper lubrication and alignment of the derailleur.

Customization and Optimization for Better Performance

To get the most out of your Campagnolo Ekar 13 RD rear derailleur, consider the following customizations and performance tips.

Upgrade the Chain

For better shifting performance and reduced wear, consider upgrading to a high-end chain designed specifically for gravel and off-road riding. A smoother, more durable chain can improve shifting accuracy and chain longevity.

Adjust the B-Screw

The B-screw on the rear derailleur controls the distance between the derailleur and the cassette. By adjusting the B-screw, you can optimize the shifting performance, especially when using cassettes with larger cog sizes. Set the B-screw so that the jockey wheel is positioned slightly above the largest cog, but not too far that it causes drag.

Comparison with Other Models

The Campagnolo Ekar 13 RD rear derailleur stands out for its precision, durability, and gravel-specific design. When compared to similar models from other brands, such as Shimano’s GRX or SRAM’s Force AXS, the Ekar 13 RD offers unique advantages for gravel riders. The Ekar system is designed to handle rough terrain with precision, ensuring reliable shifting even in the most demanding conditions.

Campagnolo Ekar 13 RD vs Shimano GRX

  • Campagnolo Ekar 13 RD: Known for its lightweight design, smooth shifting performance, and durability in rough conditions. Its unique 13-speed system offers an optimized range for gravel riders.
  • Shimano GRX: Offers solid performance but is generally considered heavier and less precise under extreme conditions. Its 11-speed setup is ideal for many riders, but may not offer the same level of gear options as the Campagnolo Ekar 13 RD.

Campagnolo Ekar 13 RD vs SRAM Force AXS

  • Campagnolo Ekar 13 RD: The Ekar offers a mechanical setup that can be more reliable and simpler to maintain for gravel riders. It’s designed specifically for gravel, providing a more stable performance in rough conditions.
  • SRAM Force AXS: Known for its wireless shifting system, the Force AXS is a good option for those who prefer electronic shifting but may come at a higher price point. It’s not as gravel-specific as the Ekar 13 RD.

Understanding Compatibility with Other Drivetrain Components

When using the Campagnolo Ekar 13 RD, it’s important to ensure that all drivetrain components are compatible. The Ekar 13-speed system is designed to work seamlessly with other Campagnolo Ekar components, including the crankset, cassette, and shifters.

Make sure to use the appropriate chain and cassette with your Ekar 13 RD derailleur for optimal shifting performance. Compatibility with other brands, such as Shimano or SRAM, may require additional adapters or adjustments.

By ensuring compatibility and proper setup, you can extend the life of your Ekar 13 RD and maintain smooth, reliable performance for many miles of gravel riding.
