Tools Required
- 5mm Allen wrench
- 2.5mm Allen wrench
- Chain tool
- Torque wrench
- Flathead screwdriver
- Phillips screwdriver
- Campagnolo-specific adapter (if required)
- Chain checker (optional)
- Clean cloth
- Lubricant (for the derailleur hanger and bolts)
Installation of the Super Record WRL Rear Derailleur
Step 1: Prepare the Bike
Before you start the installation process, ensure your bike is properly supported in a work stand, with the rear wheel removed. This will give you full access to the drivetrain and rear derailleur area. Clean the area around the derailleur hanger to avoid debris entering sensitive parts during the installation.
Step 2: Attach the Derailleur Hanger
Begin by inspecting the derailleur hanger on your frame. It must be perfectly aligned to prevent shifting issues. If necessary, use a derailleur hanger alignment tool to make sure it is straight. Once aligned, apply a small amount of grease to the threads of the derailleur hanger bolt.
Install the derailleur hanger by tightening the bolt securely, using the appropriate Allen wrench (usually 5mm). Be sure not to overtighten to avoid damaging the frame.
Step 3: Mount the Super Record WRL Rear Derailleur
The Super Record WRL Rear Derailleur comes with a direct-mount system, which is designed to simplify installation. Position the derailleur onto the derailleur hanger, ensuring it is oriented correctly with the jockey wheels facing the rear wheel. Use a 5mm Allen wrench to tighten the derailleur mounting bolt.
Be careful to avoid cross-threading the bolt as it can damage the derailleur hanger or derailleur. Tighten it securely but not excessively—most derailleur bolts should be torqued to 8-10 Nm.
Step 4: Install the Chain
Thread the chain through the jockey wheels of the derailleur. Make sure the chain runs smoothly and does not interfere with any part of the derailleur. Use a chain tool to size the chain properly, ensuring it is neither too tight nor too loose. The chain should pass smoothly through the derailleur without any snags.
Step 5: Attach the Rear Derailleur Cable
For optimal shifting performance, it’s crucial that the derailleur cable is installed correctly. Begin by attaching the derailleur cable to the derailleur’s cable clamp. Use a 2.5mm Allen wrench to tighten the bolt securely. Ensure the cable runs smoothly from the rear derailleur to the shift lever on the handlebars without kinks or excessive slack.
Step 6: Adjust the Cable Tension
Before you start shifting, make sure the cable tension is properly set. Shift the derailleur to the smallest cog, then use the barrel adjuster on the derailleur or shifter to fine-tune the tension. Proper tension ensures smooth and precise shifting performance.
Step 7: Final Tightening and Inspection
Double-check all bolts to ensure they are torqued to the recommended specifications. Verify that the derailleur moves freely through its range of motion and that there are no issues with the chain or cable. Rotate the pedals and shift through all the gears to ensure the derailleur operates smoothly.
Adjusting the Super Record WRL Rear Derailleur for Optimal Performance
Setting the Limit Screws
The limit screws on the Super Record WRL Rear Derailleur control the range of the derailleur, ensuring it does not shift beyond the largest or smallest cogs.
- High limit screw (H-screw): This screw sets the outermost position of the derailleur. Adjust it so that the derailleur moves easily to the smallest cog without overshooting.
- Low limit screw (L-screw): This screw controls the inner position of the derailleur. Set it to ensure the derailleur does not shift beyond the largest cog.
Both limit screws should be adjusted slowly, making small adjustments and testing the shifting after each change.
Fine-Tuning the Indexing
Once the limit screws are set, you can fine-tune the indexing. Shift through each gear and use the barrel adjuster to make small adjustments to the derailleur’s positioning. This will help achieve precise and smooth shifting across all gears. Make sure the chain transitions smoothly from one cog to the next without skipping or hesitating.
Troubleshooting Common Issues
Chain Dropping or Skipping
If the chain is dropping or skipping on the cogs, it could indicate a problem with the derailleur hanger alignment, chain wear, or improper cable tension. Double-check the hanger alignment with a tool and inspect the chain for wear using a chain checker tool.
If the issue persists, check the derailleur’s capacity—make sure it is compatible with your gear setup. Lastly, ensure the derailleur is properly adjusted, including the limit screws and indexing.
Jumpy Shifting
Jumpy shifting can be caused by an incorrectly adjusted derailleur or insufficient cable tension. If the derailleur is skipping gears or struggling to shift, adjust the cable tension using the barrel adjuster and ensure the derailleur hanger is correctly aligned.
Customization and Optimization for Better Performance
The Campagnolo Super Record WRL Rear Derailleur is already an exceptional component, but with some customizations, you can enhance your riding experience even further.
Use of Ceramic Bearings
For smoother shifting and reduced friction, consider upgrading the derailleur’s jockey wheels to ceramic bearings. These bearings reduce energy loss and can improve shifting performance, especially in wet conditions.
Chain Compatibility
The Super Record WRL Rear Derailleur is designed to work seamlessly with Campagnolo’s 12-speed drivetrains. To maximize performance, use a Campagnolo-specific chain, which ensures smooth shifting and optimal wear characteristics.
Comparison with Similar Models
The Super Record WRL Rear Derailleur sits at the top of Campagnolo’s line, offering unparalleled performance and precision. Compared to the Chorus or Record models, the Super Record WRL uses lighter materials and has a more refined design for professional-level performance.
If you’re looking for a more affordable alternative, the Record model offers very similar shifting performance with slightly heavier construction. For riders seeking a durable and reliable option, the Chorus is a great choice, offering excellent performance at a more accessible price point.
Compatibility with Other Drivetrain Components
The Super Record WRL Rear Derailleur is designed for use with Campagnolo’s 12-speed drivetrains. It is compatible with Campagnolo’s 12-speed cassettes, chains, and shifters. However, it is important to note that the derailleur is not compatible with drivetrains from other brands, as Campagnolo uses unique cable pull ratios and designs that differ from Shimano and SRAM components.
If you are building or upgrading your bike with a Campagnolo drivetrain, make sure all components, including the cassette, chain, and shifters, are from the same 12-speed Campagnolo series.
By following these steps and guidelines, you will have the Super Record WRL Rear Derailleur properly installed, adjusted, and optimized for superior performance on your road bike.
