Whether you’re upgrading your drivetrain or replacing an old derailleur, proper installation and maintenance are key to ensuring optimal functionality. This guide will walk you through installing, adjusting, and maintaining the Campagnolo Centaur 11s [paid link] Rear Derailleur, following best practices to achieve flawless shifting performance.
Tools Required
Before starting, gather the necessary tools to ensure a smooth installation process:
- 5mm and 4mm Allen keys [paid link]
- Torque wrench [paid link]
- Phillips screwdriver
- Chain tool
- Campagnolo 11-speed chain
- Derailleur hanger alignment tool
- Cable cutter
- Lubricant for pivot points
Installing the Campagnolo Centaur 11s Rear Derailleur
Proper installation begins with securely mounting the derailleur to the bike frame. Ensure that the derailleur hanger is aligned, as even a slight misalignment can affect shifting precision. Using a 5mm Allen key, tighten the derailleur mounting bolt to the correct torque specification. Campagnolo recommends checking that the derailleur moves freely and is not obstructed by the frame or chainstay.
Next, route the Campagnolo 11-speed chain through the derailleur, ensuring it sits correctly on the jockey wheels. The correct chain length is crucial for smooth shifting and drivetrain longevity. If you’re unsure about measuring your chain, refer to our detailed guide on How to Determine the Length of Your Bike Chain to ensure you cut it to the right length.
Adjusting the Rear Derailleur for Optimal Shifting
Once installed, fine-tuning is necessary to achieve smooth gear changes. Start by setting the high and low limit screws, which control how far the derailleur can travel in either direction.
- Setting the High Limit Screw: Shift to the smallest cog and adjust the high limit screw until the upper jockey wheel aligns perfectly with the cog.
- Setting the Low Limit Screw: Shift to the largest cog and adjust the low limit screw to prevent the derailleur from overshooting into the spokes.
Cable tension plays a vital role in crisp shifting. If shifting is sluggish or inconsistent, turn the barrel adjuster to fine-tune the tension. Gradually adjust it while shifting through the gears to ensure smooth transitions between cogs.

Additionally, ensure that B-tension adjustment is correct. This controls the gap between the upper jockey wheel and the cassette. If the derailleur sits too close, it can cause noisy shifting; too far, and shifts may be slow. Adjust the B-screw until you achieve a smooth transition between gears.
Maintaining the Campagnolo Centaur 11s Rear Derailleur
Routine maintenance will keep your derailleur performing optimally and extend its lifespan.
- Keep the derailleur clean: Dirt and grime buildup can cause sluggish shifting. Use a degreaser and soft brush to clean the derailleur regularly.
- Lubricate moving parts: Apply a light lubricant to pivot points to reduce friction and wear.
- Check derailleur hanger alignment: A bent hanger can cause poor shifting performance. Use a derailleur hanger alignment tool to inspect and adjust as needed.
- Inspect cables and housing: Frayed or worn cables can lead to inconsistent shifting. Replace them periodically to maintain smooth operation.
- Monitor chain wear: A worn-out chain accelerates drivetrain wear, including the cassette and derailleur pulleys. Learn how to check for chain wear in How to Maintain Your Bike Chain for Optimal Performance.
When to Replace Your Derailleur
Although the Campagnolo Centaur 11s [paid link] Rear Derailleur is built for durability, it may eventually need replacement due to wear or impact damage. If shifting performance remains poor despite adjustments, or if the derailleur is visibly bent, consider replacing it. Before purchasing a new one, ensure compatibility with your cassette and shifters.
