The Campagnolo Ekar 13 RD [paid link] is a standout component in the growing world of gravel cycling, offering a combination of cutting-edge technology and exceptional performance. As more cyclists adopt this specific rear derailleur in their setups, real-world feedback becomes an invaluable resource. This guide delves into rider feedback on the Campagnolo Ekar 13 RD, covering installation, adjustments, troubleshooting, and performance optimization to give a comprehensive understanding of this model’s capabilities.

Installation of the Ekar 13 RD Rear Derailleur

Installing the Campagnolo Ekar 13 RD is a relatively straightforward process for those familiar with derailleur installations. However, specific attention must be paid to ensure that the setup is correct for optimal shifting performance.

Steps to Install the Ekar 13 RD:

1. Remove the old derailleur: If upgrading from a previous model, remove the existing derailleur and any associated hardware.
2. Attach the derailleur hanger: Ensure the hanger is aligned with the frame and securely fastened.
3. Install the derailleur: Mount the Ekar 13 RD on the derailleur hanger using the provided bolt, ensuring it is properly aligned. The derailleur should sit neatly in the chainline and not interfere with the wheel’s movement.
4. Connect the derailleur to the shifter: Attach the cable to the derailleur, ensuring that it is routed through the correct cable path. A well-aligned cable will ensure smooth shifting under load.
5. Adjust the tension: Adjust the barrel adjuster to ensure the proper tension in the derailleur cable.
6. Install the chain: Make sure the chain is properly sized and threaded through the derailleur. A correctly sized chain ensures precise shifts and reduces the risk of derailleur damage.
7. Check chainline and alignment: Verify that the derailleur moves freely through all gear combinations without interference. Adjust the B-screw to fine-tune the jockey wheel’s clearance from the cassette.

By following these steps, the Ekar 13 RD should be correctly installed, ready for testing and fine-tuning.

Adjusting the Ekar 13 RD for Smooth Shifting

Once installed, proper adjustment is crucial for achieving the flawless shifting performance that Campagnolo is known for. This process includes fine-tuning the derailleur’s positioning, cable tension, and limit screws.

Key Areas for Adjustment:

• Limit Screws: The limit screws control the derailleur’s range, preventing it from shifting off the cassette. These should be set precisely for both the high and low gears. For the low gear (largest cog), ensure the derailleur does not overshift and cause chain drop. For the high gear (smallest cog), verify the derailleur doesn’t miss the cog.
• Cable Tension: Proper cable tension is critical for responsive shifting. Too much tension can cause sluggish shifts, while too little may result in missed shifts or chain skipping. The barrel adjuster is used to make minute adjustments.
• B-Screw Adjustment: The B-screw controls the distance between the jockey wheels and the cassette. Proper clearance is important to avoid interference with the cassette, especially when shifting into the larger cogs.

Riders report that after a few fine adjustments, the Ekar 13 RD performs exceptionally well, offering smooth, reliable shifts across the full gear range.

Troubleshooting Common Issues with Ekar 13 RD

Though the Ekar 13 RD is designed for durability and precision, like any mechanical component, it can encounter some common issues that require attention. Here are a few troubleshooting tips based on real-world rider feedback.

1. Skipping or Missing Shifts

• Cause: Inadequate cable tension or worn-out cables.
• Solution: Re-adjust the cable tension using the barrel adjuster. If shifting problems persist, check for frayed or damaged cables, and replace them if necessary.

2. Derailleur Noise

• Cause: Misalignment of the derailleur or poor chainline.
• Solution: Ensure that the derailleur hanger is straight and the derailleur is properly aligned with the cassette. Check for chain wear and ensure the chain is clean and lubricated.

3. Shifting Difficulties in the Large Cogs

• Cause: Incorrect B-screw setting or chain length.
• Solution: Adjust the B-screw to provide sufficient clearance between the jockey wheels and the cassette. Also, verify that the chain length is correct, as an overly long or short chain can cause shifting issues.

4. Chain Drop on Rough Terrain

• Cause: Inadequate chain retention or improper derailleur setup.
• Solution: Check that the derailleur is properly aligned and that the chainring is clean and undamaged. Additionally, a chain guide or chain catcher can be added for extra security when riding over rough terrain.

Optimizing the Ekar 13 RD for Better Performance

The Ekar 13 RD is built with gravel riders in mind, but that doesn’t mean it cannot be optimized for enhanced performance. Here are a few tips that can help riders get the most out of their derailleur.

1. Customizing Gear Ratios

Riders frequently report satisfaction with the stock gear ratios provided by Campagnolo. However, depending on the terrain you ride most often, changing the cassette or chainring sizes can better suit your riding style. Larger cogs are beneficial for steep climbs, while smaller cogs are better for flat or rolling terrain.

2. Upgrading Cables and Housing

Many riders have noted that upgrading to higher-quality cables and housing can improve shifting performance. This is particularly noticeable in muddy or wet conditions, where lower-quality cables may degrade faster. High-end cables, such as those with stainless steel cores, provide more durability and reduce friction.

3. Maintaining Cleanliness and Lubrication

Since gravel riding often involves exposure to dirt, dust, and mud, keeping the derailleur clean is essential. Regular cleaning of the derailleur, cassette, and chain, along with applying appropriate lubricants, will ensure long-term performance and reliability.

Compatibility with Other Drivetrain Components

The Ekar 13 RD is part of Campagnolo’s 13-speed gravel-specific system, and it is designed to be highly compatible with other components within the same family. However, compatibility with components from other brands or systems should be carefully considered.

Compatibility Considerations:

• Shifters: The Ekar 13 RD is designed to work exclusively with Campagnolo’s Ekar 13-speed shifters. Mixing it with non-Ekar shifters may result in unreliable shifting and poor performance.
• Crankset and Chainrings: The Ekar system is designed to work with a specific range of chainring sizes. Riders who wish to change their chainring should ensure compatibility with the 13-speed chain.
• Cassette: The Ekar 13 RD works best with Campagnolo’s 13-speed cassettes. While it is possible to use other cassettes, shifting performance may not be optimal unless specifically designed for 13-speed systems.

Comparison with Other 13-Speed Gravel Derailleurs

When comparing the Ekar 13 RD to other 13-speed gravel derailleurs on the market, the most notable competitor is SRAM’s Rival AXS 12-speed and Shimano’s GRX series. Campagnolo’s offering stands out with its refined mechanics, offering smoother, more precise shifts, especially when tackling uneven terrain.

• SRAM Rival AXS: While the Rival AXS offers electronic shifting and is a popular choice for those seeking high-tech options, the Campagnolo Ekar provides a mechanical alternative that many cyclists prefer for simplicity and reliability in harsh conditions.
• Shimano GRX: The Shimano GRX is a well-regarded gravel groupset, but it generally offers fewer gear options and less precision in shifting under heavy load compared to the Campagnolo Ekar system.

For those who prioritize mechanical simplicity and durability on gravel terrain, the Ekar 13 RD stands out as a top contender.

Conclusion

Real-world feedback from riders highlights the Campagnolo Ekar 13 RD as a highly reliable and efficient rear derailleur that performs exceptionally well in the gravel cycling scene. With careful installation, routine maintenance, and attention to adjustment, it can deliver top-tier shifting performance in challenging conditions. Customization options further enhance its adaptability, making it a solid choice for riders looking to optimize their gravel setups.
