The Campagnolo Ekar 13-speed rear derailleur is a finely tuned component designed for gravel riding, offering smooth and precise shifting even in the toughest conditions. To keep it running at peak performance, regular maintenance is essential. Dust, mud, and grime from gravel trails can cause premature wear and shifting issues if not addressed.

This guide covers everything you need to know about maintaining your Ekar 13-speed derailleur, from cleaning and lubrication to adjusting key components for optimal performance.

Understanding the Campagnolo Ekar 13-Speed Rear Derailleur

The Ekar 13-speed derailleur is a gravel-specific component built for durability, precision, and reliability. It features:

  • A clutch mechanism to prevent chain slap and maintain tension on rough terrain.
  • A carbon-reinforced polymer body for reduced weight without compromising strength.
  • Optimized pulleys and cage design for smooth and quiet shifting.

Because of its advanced design, proper maintenance is crucial to extend its lifespan and prevent common issues like misalignment, excessive friction, and poor shifting performance.

Cleaning Your Campagnolo Ekar 13-Speed Rear Derailleur

Dirt and grime can accumulate on the derailleur, affecting its ability to shift smoothly. A regular cleaning routine prevents buildup and extends the life of the derailleur components.

Step-by-Step Cleaning Process

  1. Remove the Rear Wheel: This provides better access to the derailleur and jockey wheels.
  2. Degrease the Jockey Wheels and Pivots: Use a biodegradable degreaser to break down dirt and oil. Avoid spraying directly into bearings.
  3. Clean the Derailleur Body: Use a soft brush or microfiber cloth with mild soapy water to wipe away dust and grime.
  4. Flush Out Dirt from Springs and Mechanisms: Use compressed air or a gentle rinse (avoid high-pressure water, which can force dirt inside bearings).
  5. Dry Thoroughly: Wipe down all components with a dry, lint-free cloth.
  6. Inspect for Wear: Look for signs of wear on jockey wheels, pivots, and bolts.

For best results, clean your derailleur after every few rides, especially if riding in wet or dusty conditions.

Lubricating the Campagnolo Ekar 13-Speed Rear Derailleur

Proper lubrication ensures smooth movement and prevents premature wear. Over-lubrication can attract dirt, while under-lubrication can cause friction and poor shifting.

Where to Apply Lubrication

  • Jockey Wheel Bearings: Apply a small amount of dry lube [paid link] to keep them running smoothly.
  • Clutch Mechanism: Light lubrication can reduce stiffness without compromising tension.
  • Pivots and Springs: A drop of Teflon-based oil will help prevent corrosion and ensure smooth movement.

Avoid Over-Lubrication

  • Wipe off excess lube after application.
  • Avoid getting lubricant on the cassette, chainrings, or braking surfaces.

Lubricate your derailleur every 200-300 miles or after riding in wet and muddy conditions.

Adjusting the Campagnolo Ekar 13-Speed Rear Derailleur for Optimal Performance

Even with proper maintenance, your derailleur may need occasional adjustments to keep shifting precise.

1. Checking the Limit Screws

The limit screws prevent the derailleur from shifting too far inward or outward. If shifting feels off, follow these steps:

  • H-Limit Screw: Ensures the derailleur does not shift the chain into the spokes.
  • L-Limit Screw: Prevents the derailleur from shifting the chain off the smallest cog.

Use a 2mm Allen key to fine-tune the limit screws if necessary.

2. B-Tension Adjustment

The B-tension screw controls the derailleur’s distance from the cassette. If shifting feels sluggish, adjust the B-screw to ensure proper chain engagement.

3. Clutch Tension Check

The clutch system prevents chain slap. If it feels too stiff or too loose, adjust it according to your riding preference.

Common Issues and How to Fix Them

Even with proper maintenance, you might experience occasional shifting problems. Here’s how to diagnose and fix them.

1. Chain Skipping or Poor Shifting

  • Cause: Worn jockey wheels or chain.
  • Fix: Inspect and replace worn components as needed.

2. Noisy Shifting

  • Cause: Dirty or dry derailleur pivots.
  • Fix: Clean and lubricate the derailleur to restore smooth operation.

When to Replace Worn Components

Over time, certain parts of your derailleur will wear out. Replacing them at the right time ensures continued performance.

  • Jockey Wheels: Replace when the teeth appear worn or shifting becomes inconsistent.
  • Derailleur Hanger: If bent or damaged, replace it to restore proper alignment.
  • Inner Cables: Frayed or stretched cables should be replaced for precise shifting.

Final Thoughts

Regular maintenance is key to keeping your Campagnolo Ekar 13-speed rear derailleur performing at its best. Cleaning, lubricating, and adjusting the derailleur at the right intervals will prevent costly repairs and ensure smooth shifting on every ride.

By following these steps, you’ll get the most out of your Ekar 13-speed derailleur, whether you’re tackling rugged gravel terrain or enjoying a long endurance ride.
