The Campagnolo Ekar 1×13 rear derailleur is a cutting-edge component designed specifically for gravel bikes. With its sleek design and precision engineering, this derailleur stands out in the competitive world of gravel-specific drivetrains. In this article, we’ll explore the key features of the Ekar 1×13 rear derailleur, its installation and maintenance, and how it compares with other models on the market to help you decide whether it’s the best option for your gravel bike setup.

Key Features of the Ekar 1×13 Rear Derailleur

The Campagnolo Ekar 1×13 rear derailleur offers a variety of features aimed at improving performance and durability in challenging gravel conditions. Here are the standout aspects:

  • 13-Speed Capability: The Ekar system features a 1×13 drivetrain, offering an optimal range of gears for gravel riders without the complexity of front derailleurs.
  • Precision Shifting: Thanks to Campagnolo’s signature shifting technology, the Ekar derailleur ensures smooth, precise shifting under load, even on rough terrain.
  • Wide Gear Range: The 13-speed setup allows for a broad gear range, perfect for tackling both steep climbs and fast, flat sections on gravel roads.
  • Lightweight Design: Made from durable materials, the derailleur maintains a lightweight profile, which is crucial for gravel riders who need to manage both weight and reliability.
  • Compatibility: The Ekar rear derailleur is specifically designed for use with Campagnolo’s Ekar 1×13 drivetrain, ensuring optimal performance and compatibility with other Campagnolo components.

Installation of the Campagnolo Ekar 1×13 Rear Derailleur

Proper installation of the Ekar 1×13 rear derailleur is essential for optimal performance and longevity. Follow these steps for a flawless setup:

Tools Required:

  • 5mm Allen wrench
  • 2mm Allen wrench
  • Torque wrench
  • 10mm spanner
  • Chain tool
  • Campagnolo Ekar 1×13 cassette and chain
  • Phillips screwdriver

Installation Steps:

  1. Mount the Derailleur Hanger: Ensure the derailleur hanger is straight and securely installed on the frame.
  2. Attach the Derailleur: Using a 5mm Allen wrench, attach the Ekar derailleur to the derailleur hanger. Make sure it’s tightened to the recommended torque setting (around 6-8 Nm).
  3. Install the Chain: Use the appropriate chain for the Ekar system, ensuring it is properly sized for your bike. The Ekar drivetrain requires a specific chain to function correctly, so make sure you use the Campagnolo Ekar chain.
  4. Set the B-Screw: The B-screw controls the distance between the derailleur’s jockey wheels and the cassette. Adjust it to maintain optimal clearance. Campagnolo suggests a B-screw setting that allows for smooth shifting across the entire gear range.
  5. Adjust the Limit Screws: Adjust the high and low limit screws to ensure that the derailleur doesn’t overshift into the spokes or drop off the cassette in either direction.
  6. Test the Shifting: Shift through all gears and fine-tune the barrel adjusters for smooth and precise transitions between cogs.

Maintenance of the Campagnolo Ekar 1×13 Rear Derailleur

To ensure the longevity of your Campagnolo Ekar 1×13 rear derailleur, regular maintenance is required. Here are the essential tasks to keep your derailleur running smoothly:

Cleaning and Lubrication:

  • Clean the derailleur frequently to remove dirt, mud, and debris, especially after rides in wet conditions. Use a gentle degreaser and brush to remove any built-up grime.
  • Lubricate the derailleur pivots and jockey wheels with appropriate chain lube or light grease to prevent wear and ensure smooth operation.

Inspect for Wear:

  • Regularly check the derailleur hanger for any signs of bending or damage.
  • Inspect the derailleur jockey wheels for wear, especially after long rides on gravel or rough trails. If they show signs of damage, replace them promptly to avoid affecting shifting performance.

Cable Tension Adjustment:

  • Over time, the tension of the derailleur cable can loosen. Periodically check the cable tension and adjust the barrel adjuster to maintain precise shifting. If the shifting becomes sluggish or inaccurate, you may need to replace the cable.

Replacing the Chain and Cassette:

  • Since the Ekar system operates with a 1×13 setup, it is essential to replace both the chain and cassette at the same time when they reach the end of their lifespan. This ensures that your drivetrain remains in sync and performs optimally.

Troubleshooting Common Set-Up Issues

Despite being a high-quality component, the Ekar 1×13 rear derailleur can encounter some setup issues. Here are common problems and how to address them:

Sluggish Shifting:

  • Cause: Poor cable tension or dirty components.
  • Solution: Check the cable tension using the barrel adjuster. Clean and lubricate the derailleur and chain thoroughly. If the issue persists, replace the chain or adjust the B-screw for optimal jockey wheel clearance.

Chain Drops:

  • Cause: Improper chain length or misadjusted derailleur limits.
  • Solution: Ensure the chain is correctly sized for your bike and that the derailleur limits are properly set to avoid overshifting. Also, ensure that the derailleur hanger is aligned correctly.

Cross-Chaining Noise:

  • Cause: Incorrect gear selection, leading to cross-chaining.
  • Solution: Ensure that the rider is using the appropriate gears for the terrain, avoiding extreme gear combinations such as the large chainring with the large cog.

Customization and Optimization for Better Performance

The Ekar 1×13 rear derailleur can be further customized and optimized to meet the specific needs of gravel riders. Here are some strategies:

Gear Ratios:

  • Riders can experiment with different cassette options to find the optimal gear range. The 13-speed system provides a wide range, but it can be fine-tuned with specific ratios depending on terrain preferences.

Shifting Precision:

  • To improve shifting performance, consider using a high-quality cable and housing that minimizes friction. Also, ensuring that the derailleur hanger is perfectly aligned will prevent any shifting errors.

Jockey Wheel Upgrade:

  • Upgrading the derailleur’s jockey wheels to ceramic or high-performance materials can reduce friction, enhancing the overall drivetrain efficiency.

Comparison with Other Rear Derailleurs for Gravel Bikes

The Campagnolo Ekar 1×13 rear derailleur is not the only option for gravel riders. Here’s how it compares to some other popular models:

  • Shimano GRX Di2: The Shimano GRX Di2 offers electronic shifting and a wide gear range, making it a strong competitor to the Ekar system. However, it’s typically heavier and more expensive. The Ekar system excels in weight and simplicity, with mechanical shifting and fewer parts to maintain.
  • SRAM Rival 1: SRAM’s Rival 1×11 drivetrain is another option for gravel riders, offering a 1x setup but with fewer gears. While it is more affordable, it doesn’t provide the same range or precision of the Ekar system.

Overall, the Ekar 1×13 system is ideal for riders who prioritize lightweight performance and a broad gear range without the complexity of electronic systems.

Compatibility with Other Drivetrain Components

The Campagnolo Ekar 1×13 rear derailleur is designed to work seamlessly with Campagnolo’s 1×13 system, including the Ekar cassette and chain. Compatibility with other drivetrain components, particularly those from other brands like Shimano or SRAM, is not recommended due to differences in cable pull ratios and gear spacing. Using non-Ekar components may lead to inefficient shifting and potential damage to the derailleur.

However, if you’re looking for maximum performance, using a full Campagnolo Ekar drivetrain will ensure the most reliable and efficient setup.
