The Campagnolo Record EPS 11s [paid link] front derailleur is a high-performance electronic shifting component designed for precise and effortless gear changes. As part of Campagnolo’s top-tier Electronic Power Shift (EPS) system, it provides smooth and reliable front shifting when properly installed and adjusted. However, setting up the EPS 11s front derailleur requires technical precision to ensure optimal function and longevity.

This guide will cover the complete installation, adjustment, and maintenance process to help you get the most out of your Record EPS 11s [paid link] front derailleur. Whether you’re setting it up for the first time or troubleshooting performance issues, follow this in-depth tutorial for expert-level [paid link] results.

Tools Required

Before starting the installation, ensure you have the necessary tools:

  • 2.5mm, 3mm, and 4mm Allen wrenches [paid link]
  • Torque wrench [paid link] with Nm settings
  • Phillips screwdriver
  • Campagnolo EPS interface tool (for diagnostics and updates)
  • Isopropyl alcohol and a clean rag
  • Cable ties (for wire routing)
  • Chain tool (if replacing the chain)

Installation of the Record EPS 11s Front Derailleur

1. Positioning the Derailleur on the Frame

  • Mount the Record EPS 11s [paid link] front derailleur onto the braze-on mount. If your bike does not have a braze-on mount, use a compatible clamp adapter.
  • Align the outer derailleur plate parallel to the large chainring. The gap between the outer plate and the chainring teeth should be 1-2mm.
  • Lightly tighten the mounting bolt to hold the derailleur in place, but do not fully torque it yet.

2. Connecting the EPS System

  • Route the EPS wire from the front derailleur to the power unit and junction box. Ensure it follows the correct cable routing specified by Campagnolo.
  • Plug the EPS wire into the derailleur port until it clicks into place.
  • Secure the wire along the frame using cable ties, ensuring it does not interfere with moving parts.

3. Torque the Mounting Bolt

  • Once the derailleur is positioned correctly, torque the mounting bolt to 5-7 Nm using a torque wrench [paid link].
  • Double-check alignment before tightening completely.

4. Installing the Chain

  • If installing a new chain, size it correctly according to Campagnolo’s specifications.
  • Thread the chain through the front derailleur and rear derailleur, ensuring proper routing.
  • Connect the chain using the correct Campagnolo Ultra-Link system.

Adjusting the Record EPS 11s Front Derailleur

1. Setting the Electronic Limit Positions

  • Power on the EPS system.
  • Shift the front derailleur to the small chainring. Use the Campagnolo interface to enter adjustment mode.
  • Adjust the lower limit position so that the inner cage plate is 0.5-1mm from the chain.
  • Shift to the big chainring and adjust the upper limit to ensure smooth shifting without chain rub.

2. Fine-Tuning with Micro-Adjustments

  • If there is chain rub or sluggish shifting, use the EPS system’s micro-adjust function.
  • Enter adjustment mode and use the EPS interface to make small tweaks in 0.2mm increments until shifting is smooth and quiet.

3. Checking the Front Shifting Performance

  • Shift between chainrings multiple times to ensure smooth operation.
  • Check for chain drop or hesitation when shifting. If necessary, refine micro-adjustments.
  • Ensure the derailleur does not over-shift, which can cause chain drop on high-torque shifts.

Maintaining the Record EPS 11s Front Derailleur

1. Regular Cleaning

  • Wipe down the derailleur with isopropyl alcohol and a clean rag after rides to remove dirt and grime.
  • Avoid using high-pressure water, as it can force moisture into electronic connections.

2. Inspecting and Updating Firmware

  • Use the Campagnolo EPS interface tool to check for firmware updates periodically.
  • Ensure all EPS connections are secure and free from moisture or corrosion.

3. Checking Bolts and Connections

  • Inspect the derailleur mounting bolt and torque it if necessary.
  • Check EPS wiring for damage, especially at connection points.

4. Battery Management

  • Ensure your EPS system is charged. The system provides warnings when the battery is low.
  • Store your bike with the EPS system powered off to prevent battery drain.

Troubleshooting Common Issues

1. Slow or Inconsistent Shifting

  • Check the EPS battery charge level [paid link]. Low power can affect shift performance.
  • Ensure the derailleur is properly aligned and that micro-adjustments are fine-tuned.

2. Chain Rub in Certain Gears

  • Use the micro-adjust function to slightly move the derailleur cage away from the chain.
  • Confirm that the chainline is correct and that chain wear is not affecting shifting.

3. No Response from the Front Derailleur

  • Ensure the EPS system is turned on.
  • Check all wire connections and reseat them if necessary.
  • Connect the bike to the Campagnolo interface tool for error diagnosis.

4. Chain Drops During Shifting

  • Verify that the derailleur’s high and low limit positions are set correctly.
  • Ensure the chainring and chain are not excessively worn.

Comparison with Similar Models

The Record EPS 11s front derailleur is comparable to other Campagnolo EPS models, such as the Super Record EPS and Chorus EPS. The main differences include:

  • Weight: The Super Record EPS is slightly lighter due to carbon fiber components.
  • Material: The Record EPS 11s uses a mix of alloy and carbon fiber, offering a balance of durability and performance.
  • Shifting Speed: All EPS models feature electronic shifting, but firmware tuning can make small differences in responsiveness.

If you’re considering an upgrade, the Super Record EPS offers marginally improved performance but at a significantly higher price.

Final Thoughts

The Campagnolo Record EPS 11s front derailleur is an advanced electronic shifting component that requires precise setup and regular maintenance to perform at its best. By following this guide, you can ensure a smooth installation, fine-tune adjustments for optimal shifting, and maintain the derailleur for long-term reliability.
