The Campagnolo Ekar 1×13 Rear Derailleur is part of the brand’s ambitious push into the world of gravel and adventure cycling. This derailleur aims to provide cyclists with the performance and reliability expected from Campagnolo’s high-end road products, but tailored for off-road conditions. Here, we dive into the practical, real-world performance of this component, focusing on its installation, adjustment, maintenance, and common troubleshooting tips.

Installation of the Campagnolo Ekar 1×13 Rear Derailleur

The installation of the Campagnolo Ekar 1×13 Rear Derailleur requires a careful approach to ensure smooth shifting performance and optimal drivetrain function. Here’s a step-by-step breakdown of the installation process.

Tools Required:

  • 5mm hex wrench
  • 3mm hex wrench
  • 10mm open-end wrench
  • Torque wrench
  • Chain tool
  • Ekar-specific cassette tool
  • Allen key set

Step-by-Step Installation:

  1. Remove the old derailleur: If you’re upgrading from another derailleur system, carefully remove the existing derailleur by unscrewing the mounting bolt and detaching the chain from the derailleur.
  2. Install the derailleur hanger: Ensure that the derailleur hanger is properly aligned and torqued to the correct specifications (usually 5-7Nm) to prevent any shifting issues.
  3. Attach the Ekar derailleur: Using a 5mm hex wrench, attach the derailleur to the derailleur hanger. Make sure it is securely tightened.
  4. Install the chain: Use a chain tool to size and install the chain on the Ekar system, ensuring that the chain runs smoothly over the jockey wheels without excessive slack.
  5. Mount the cassette: Install the Ekar-specific cassette using the correct tools. The 1×13 system uses a 13-speed cassette, which needs to be positioned properly on the freehub body.
  6. Adjust the limit screws: Set the low and high limit screws on the derailleur to prevent it from shifting beyond the cassette’s range.
  7. Fine-tune the derailleur: Adjust the B-screw and derailleur cage position to ensure proper clearance with the cassette. Check for chain clearance and smooth shifting across the entire range.

Adjustment and Maintenance of the Campagnolo Ekar 1×13 Rear Derailleur

Proper adjustment and regular maintenance are critical to ensuring the long-term performance of your Campagnolo Ekar 1×13 Rear Derailleur. Here’s how to keep your derailleur functioning optimally.

Adjustment:

  1. Indexing the Shifting: Once the derailleur is installed, use the barrel adjuster to fine-tune the indexing. Start with the chain in the smallest cog, and shift through each gear. Adjust the barrel adjuster on the derailleur or shifter to eliminate any hesitation or skipping between gears.
  2. Derailleur Position: The B-screw plays a crucial role in ensuring the derailleur stays in the correct position relative to the cassette. Adjust the B-screw to achieve the ideal distance between the derailleur and the cassette, typically around 5-6mm for smooth shifting.
  3. Cable Tension: If shifting becomes sluggish or unreliable, check the tension in the derailleur cable. Increasing the tension slightly may improve shifting, while decreasing it may help if the derailleur overshifts.

Maintenance:

  1. Cleaning: Regularly clean the derailleur, jockey wheels, and chain to remove dirt, mud, and debris. This is especially important for gravel riders, as dirt can build up quickly and affect performance.
  2. Lubrication: Apply appropriate lubricant to the derailleur’s moving parts, focusing on the jockey wheels and pivot points. Use a dry lube for dusty conditions and a wet lube for rainy or wet conditions.
  3. Chain Wear: Keep an eye on chain wear and replace the chain regularly to avoid excessive wear on the cassette and derailleur.

Troubleshooting Common Set-Up Issues

Even with careful installation and maintenance, issues can arise with the Campagnolo Ekar 1×13 Rear Derailleur. Below are some common issues and their solutions.

Issue 1: Skipping or Hesitation During Shifting

  • Cause: Incorrect derailleur alignment or cable tension.
  • Solution: Recheck the derailleur hanger alignment using a derailleur hanger alignment tool. Adjust the cable tension using the barrel adjuster, and ensure the limit screws are properly set.

Issue 2: Chain Dropping Off the Cassette

  • Cause: The derailleur may not be set correctly in relation to the cassette.
  • Solution: Adjust the B-screw to ensure proper derailleur positioning. Make sure the derailleur cage has the correct clearance and does not make contact with the cassette in any gear.

Issue 3: Slow or Unresponsive Shifting

  • Cause: Dirty derailleur or lack of lubrication.
  • Solution: Clean the derailleur and chain thoroughly, and apply lubricant to the moving parts. If shifting remains unresponsive, inspect the derailleur pulley wheels for wear and replace them if needed.

Customization and Optimization for Better Performance

The Campagnolo Ekar 1×13 Rear Derailleur can be optimized for better performance through small adjustments and customizations. Here’s how you can make the most of your derailleur system.

1. Gear Ratios

The Ekar system is designed for gravel and adventure riding, where a wide gear range is essential. Riders can experiment with the cassette’s gear ratios to find the best fit for their riding style. Opt for a larger cog if tackling steep, technical terrain or a tighter ratio for faster, flatter roads.

2. Chain Selection

Selecting the right chain is crucial for performance. A narrower chain, designed for 13-speed systems, helps with the precise shifting needed on gravel and dirt roads. Ensure the chain is compatible with the Ekar 1×13 system to maintain smooth performance.

3. Derailleur Hanger and Mounting

If you are using the Ekar derailleur on a custom bike, it’s important to ensure the derailleur hanger is of the correct geometry. Small changes in the hanger alignment can affect shifting performance, so consider investing in a high-quality hanger that maintains perfect alignment under rough conditions.

Comparison with Similar Models

While the Ekar 1×13 Rear Derailleur is a standout in its class, it is useful to compare it to similar models on the market. Here’s how it stacks up against competitors.

Shimano GRX Di2 (1×11)

  • Shifting Performance: The Shimano GRX Di2 system offers electronic shifting, which can provide faster, more accurate shifts compared to the mechanical Ekar system. However, some riders prefer the mechanical feel and simplicity of the Ekar system.
  • Durability: The Ekar derailleur is praised for its durability in harsh conditions. The GRX Di2, being electronic, requires more maintenance, especially with the battery and wiring.
  • Compatibility: Shimano GRX offers a greater variety of drivetrain options, including 2x setups, which may be more suited to riders looking for a wider range of gears.

SRAM Force AXS 1×12

  • Shifting Performance: SRAM Force AXS provides wireless shifting with a 12-speed range, making it more convenient but potentially more prone to signal interference compared to the Ekar’s mechanical design.
  • Durability: The SRAM system is lightweight but less durable in extremely harsh gravel conditions compared to the Ekar, which is built for rugged use.
  • Compatibility: SRAM’s AXS system offers better integration with other electronic components but lacks the mechanical simplicity and reliability of the Ekar 1×13 Rear Derailleur.

Understanding Compatibility with Other Drivetrain Components

The Campagnolo Ekar 1×13 Rear Derailleur is part of a complete 1×13 drivetrain system, and ensuring compatibility with other components is crucial for performance.

  • Shifters: The Campagnolo Ekar 1×13 system is specifically designed for use with Campagnolo’s Ekar shifters, which have a unique cable pull ratio. Attempting to pair this derailleur with shifters from other brands or models may result in poor shifting performance.
  • Cassettes: The Ekar 1×13 Rear Derailleur is compatible with the Ekar 13-speed cassette, which is designed with a specific cog range for gravel riding. Attempting to use a different cassette may cause poor shifting or chain drop.
  • Cranksets and Bottom Brackets: The Ekar system is designed to work with 1x cranksets, typically with a wide range of chainrings suited for gravel riding. It’s essential to ensure your crankset and bottom bracket are compatible with the rest of the drivetrain.

By paying attention to the compatibility of each component within the system, cyclists can maximize their riding experience and avoid unnecessary issues.
