The Campagnolo Ekar WRL rear derailleur [paid link] represents a leap forward in performance and durability within the world of gravel and endurance cycling. This review will delve into its installation, adjustment, troubleshooting, customization, and its compatibility with other drivetrain components. Additionally, we’ll compare it to other similar models and provide insight into optimizing its performance for various riding conditions.
Installation of the Ekar WRL Rear Derailleur
Installing the Campagnolo Ekar WRL rear derailleur requires precision and attention to detail to ensure optimal shifting performance. Here is a step-by-step guide to help with the installation:
- Prepare the Bike: Begin by removing the rear wheel and ensuring that the frame is clean and free from debris.
- Install the Ekar WRL Derailleur Hanger: If your bike frame doesn’t have a direct derailleur mount, you’ll need a derailleur hanger that is compatible with the Ekar system. Ensure that the hanger is aligned properly.
- Mount the Derailleur: Attach the derailleur to the derailleur hanger using a 5mm Allen bolt. Tighten the bolt sufficiently to hold the derailleur in place without over-tightening.
- Thread the Chain: Route the chain through the jockey wheels and ensure it runs smoothly through the derailleur.
- Attach the Rear Shifter Cable: The Ekar WRL system uses a mechanical shifter, so you’ll need to connect the shift cable to the derailleur’s cable fixing bolt. Tighten the bolt to secure the cable in place.
- Reinstall the Rear Wheel: Once everything is mounted and the derailleur is in place, reinstall the rear wheel, making sure the axle is securely in position.
Adjustment and Setup
Once the installation is complete, fine-tuning the derailleur is crucial for smooth and precise shifting. Here’s how you can adjust the Ekar WRL rear derailleur:
1. Adjust the B-Screw
The B-screw controls the distance between the derailleur’s jockey wheels and the cassette. To adjust it:
- Shift to the smallest chainring and the smallest cog on the cassette.
- Turn the B-screw to fine-tune the gap between the jockey wheels and the cassette. A proper gap ensures optimal shifting performance.
2. Set the High and Low Limit Screws
The limit screws prevent the derailleur from shifting beyond the outermost gears, ensuring the chain doesn’t fall off.
- Set the high-limit screw when the derailleur is in the smallest cog, ensuring the derailleur doesn’t overshoot.
- Set the low-limit screw when the derailleur is in the largest cog, ensuring the derailleur doesn’t shift too far into the spokes.
3. Cable Tension Adjustment
Proper cable tension is essential for precise shifting. To adjust:
- Shift through all the gears and check for any skipping or missed shifts.
- Adjust the barrel adjuster on the derailleur or shifter to either tighten or loosen the cable tension, achieving smooth shifts across the range.
Troubleshooting Common Issues
1. Skipping Gears
If the derailleur is skipping gears or missing shifts, the likely causes could be improper cable tension or misalignment. Recheck the cable tension and ensure the derailleur hanger is straight.
2. Chain Drops
If the chain frequently drops, it may be due to an improper B-screw setting or limit screw misalignment. Make sure that both screws are set correctly to prevent over-travel in either direction.
3. Slow Shifting
If shifts are slow, check the derailleur for cleanliness. A dirty derailleur can cause sluggish performance. Clean the derailleur and lubricate the moving parts to restore smooth shifting action.
Customization and Optimization for Performance
To get the most out of your Campagnolo Ekar WRL rear derailleur, certain customization options and performance optimizations can help. Here are some key areas to consider:
1. Optimizing Chain Length
A properly sized chain ensures smooth shifting and reduces unnecessary wear on the drivetrain. When setting up the chain, use the “largest chainring and largest cog” method to determine the optimal length. Ensure that the derailleur can handle the maximum extension of the chain without overstretching.
2. Upgrading to Ceramic Bearings
For riders seeking the best possible performance, upgrading the jockey wheels to ceramic bearings can reduce friction and improve drivetrain efficiency, especially during long gravel or endurance rides.
3. Fine-Tuning the Shifter Position
The position of the shifter on the handlebars can greatly influence shifting comfort and response. Experiment with shifter positioning to ensure that your thumb or finger is comfortably reaching the lever while riding.
Comparison with Other Models
When comparing the Campagnolo Ekar WRL rear derailleur with other similar models in the gravel and endurance cycling market, it stands out due to its unique design and durability. Here’s a look at how it stacks up against other popular rear derailleurs:
1. Shimano GRX 800
While the Shimano GRX 800 is a solid choice for gravel riders, the Campagnolo Ekar WRL offers more precise, quicker shifts with less effort due to its advanced mechanics. The Ekar system also features an innovative 13-speed configuration that offers a wider gear range compared to the Shimano GRX 800’s 11-speed setup.
2. SRAM Force AXS
SRAM Force AXS is another popular option, especially for those who prefer electronic shifting. However, the Ekar WRL offers an advantage for riders seeking mechanical simplicity with consistent performance in harsh conditions. The Ekar’s ability to handle gravel and mixed-terrain rides is another factor that puts it ahead of the competition.
Compatibility with Other Drivetrain Components
The Campagnolo Ekar WRL rear derailleur is designed to be used exclusively with Campagnolo’s Ekar 13-speed groupset. This ensures perfect compatibility and optimized performance when paired with other Ekar components, such as the Ekar crankset, shifters, and cassette.
1. Cassette Compatibility
The Ekar WRL rear derailleur is compatible with Campagnolo’s 13-speed Ekar cassette. Using non-Ekar cassettes may lead to suboptimal shifting performance due to differences in gear ratios and spacing.
2. Chain Compatibility
Campagnolo’s 13-speed Ekar chain is designed specifically for use with the Ekar drivetrain. Using a non-Ekar chain may cause issues with shifting and derailleur performance due to differences in chain width and design.
3. Shifter Compatibility
For the best performance, the Ekar WRL rear derailleur should be used with Campagnolo’s Ekar shifters. Mixing and matching with other brands or shifter models may result in inconsistent or sluggish shifting.
Conclusion
The Campagnolo Ekar WRL rear derailleur is a high-performance, durable component that excels in gravel and endurance cycling. Its precise shifting, easy maintenance, and robust build make it an ideal choice for riders who demand reliability and efficiency in tough riding conditions. Whether you’re building a new bike or upgrading your current setup, the Ekar WRL rear derailleur offers an excellent balance of performance and durability for gravel enthusiasts.
