The Campagnolo Ekar 13 RD [paid link] rear derailleur is an exceptional piece of engineering designed for gravel and road bike riders seeking a lightweight, reliable, and high-performing drivetrain. One of the key components to maintaining its longevity and performance is ensuring that the pulleys are well-lubricated. The pulleys play a crucial role in ensuring smooth and efficient shifting by guiding the chain over the jockey wheels. Over time, dirt and moisture can accumulate, causing friction and premature wear. Proper lubrication will help maintain the optimal performance of the Ekar 13 RD.

Tools Required

• Lubricant (preferably a wet lube or light grease suitable for derailleur pulleys)
• Clean rags
• Bike stand or work stand
• 5mm Allen wrench (if required to remove the derailleur)
• Chain cleaner (optional, if you want to clean the chain before lubrication)
• Small brush (optional, for cleaning the pulleys)

Preparation and Safety Measures

Before starting the lubrication process, ensure that the bike is securely mounted on a stand. This will allow easy access to the rear derailleur and the pulleys. If you have not already, clean your drivetrain to remove any dirt or debris that may interfere with the lubrication process. This will help ensure that the lubricant remains effective for longer periods without attracting excessive dirt.

If your bike has recently been ridden in wet or muddy conditions, consider cleaning the derailleur pulleys with a small brush or chain cleaner before applying lubricant.

Step-by-Step Guide to Lubricating the Ekar 13 RD Rear Derailleur Pulleys

1. Inspect the Pulleys for Wear or Damage

Before applying any lubrication, carefully inspect the pulleys for signs of wear. The teeth of the pulleys should be smooth and free from any cracks or significant wear. If there is excessive damage, you may need to replace the pulleys to ensure optimal shifting performance. If the pulleys appear to be in good condition, proceed to the lubrication step.

2. Remove the Rear Derailleur (If Necessary)

If you find it difficult to access the pulleys, or if you’re performing a deeper cleaning, you may need to remove the derailleur from the bike. To do this, use a 5mm Allen wrench to remove the bolts securing the derailleur hanger. Once the derailleur is removed, set it on a clean surface for easy access to the pulleys.

3. Clean the Pulleys (Optional)

Using a small brush or chain cleaner, gently clean the pulleys to remove any dirt, grime, or old lubricant. Be sure to clean both the jockey wheels and the surrounding area. This ensures that the new lubricant will be applied to a clean surface, enhancing its effectiveness. Use a clean rag to wipe away any excess cleaner.

4. Apply Lubricant to the Pulleys

Once the pulleys are clean, apply a small amount of lubricant to the teeth and rotating parts of the pulleys. Use a lubricant that is specifically designed for derailleur pulleys, such as a light grease or a wet chain lubricant. Apply the lubricant sparingly to avoid over-lubricating, which can attract dirt and cause excessive wear over time. Ensure that the lubricant is evenly spread across the pulley surface, especially the areas that come into contact with the chain.

5. Rotate the Pulleys

After applying the lubricant, rotate the pulleys manually to ensure the lubricant is evenly distributed across the teeth and bearings. This step helps work the lubricant into the moving parts, ensuring smooth rotation and reducing friction. You may also choose to shift through the gears while the bike is on the stand to check the performance of the derailleur.

6. Wipe Away Excess Lubricant

Use a clean rag to wipe away any excess lubricant from the pulleys and derailleur. Leaving excess lubricant on the surface can lead to the accumulation of dirt and debris, which may reduce the performance of the pulleys. Make sure that the pulleys are lightly lubricated, but not dripping.

7. Reinstall the Derailleur (If Removed)

If you had to remove the derailleur to access the pulleys, carefully reinstall it on the derailleur hanger. Tighten the bolts with the 5mm Allen wrench and double-check that the derailleur is securely in place.

8. Test the Shifting Performance

Once everything is reassembled, test the bike’s shifting to ensure smooth and precise gear changes. If the shifting feels sluggish or uneven, check that the derailleur hanger is aligned correctly and that the pulleys are rotating freely. If necessary, make minor adjustments to the derailleur to fine-tune the shifting performance.

Troubleshooting Common Issues

• Excessive Noise or Poor Shifting: If you notice increased noise or difficulty shifting after lubrication, it could indicate that too much lubricant was applied or that dirt has accumulated. Clean the pulleys again and apply a smaller amount of lubricant. Additionally, check the derailleur hanger alignment and ensure the chain is in good condition.
• Pulleys Not Rotating Smoothly: If the pulleys feel stiff or do not rotate smoothly after lubrication, this could be a sign of worn bearings or an issue with the pulley assembly. Consider replacing the pulleys or the bearings if they are damaged.
• Lubricant Attracting Dirt: If the pulleys are accumulating more dirt than usual, it may be a sign of over-lubrication. In this case, wipe off the excess lubricant and apply a more minimal amount.

Customization and Optimization

To further optimize the performance of your Campagnolo Ekar 13 RD, consider fine-tuning the rear derailleur settings and making adjustments to your chain. A well-lubricated and maintained derailleur will significantly enhance the smoothness and precision of your shifting performance, especially in challenging gravel or road conditions.

Using a high-quality lubricant specifically designed for derailleur systems can prevent dirt and moisture from interfering with the shifting mechanism, ensuring that your drivetrain operates at its best. Additionally, for riders looking for extra performance, it’s important to keep the derailleur aligned and check the chain regularly for wear. A properly adjusted derailleur combined with well-maintained pulleys will result in a highly efficient drivetrain, providing consistent and reliable shifting performance throughout your ride.

Comparison with Similar Models

The Campagnolo Ekar 13 RD stands out in the gravel and road bike world due to its lightweight design, precision shifting, and robust construction. When compared to other models like Shimano’s GRX or SRAM’s Rival AXS, the Ekar offers an exceptional balance between weight, durability, and smoothness in shifting. Lubricating the pulleys on the Campagnolo Ekar system is just as crucial as it is for other drivetrains, but the unique features of the Ekar—such as its 13-speed setup—require a bit more care and attention to ensure the smooth operation of the derailleur.

By focusing on proper maintenance, including regular lubrication, you can ensure that the Ekar 13 RD continues to deliver a top-tier performance for years, whether you’re navigating gravel roads or racing on the tarmac.
