The Campagnolo Athena EPS Ergopower [paid link] shifters are an advanced choice for road cyclists who demand precision and reliability from their gear-changing system. Offering electronic shifting technology, these shifters ensure smooth, accurate, and fast gear transitions that help elevate your riding experience.

In this comprehensive guide, we will cover everything you need to know about installing, adjusting, maintaining, and troubleshooting the Athena EPS Ergopower [paid link] shifters, ensuring you maximize their performance and lifespan.


Tools Required

Before you dive into the installation and maintenance process, it’s essential to gather all the necessary tools. Here’s a list of what you’ll need:

  • Flathead screwdriver (for adjusting shifter tension)
  • Philips screwdriver (for mounting components)
  • Torque wrench [paid link] (for precise torque settings)
  • Cable cutters (for trimming cables)
  • Crimping tool (for cable ends)
  • Allen wrenches [paid link] (for installing and adjusting various parts)
  • Grease (for lubrication)
  • Clean cloths (for wiping down parts and cleaning)
  • Bike stand [paid link] (optional, but helpful for stability during installation)
  • Shimano-compatible gear cables (or Campagnolo-compatible cables, if needed)

Having these tools ready will make the installation and maintenance process much easier and more efficient.


Installing Athena EPS Ergopower Shifters

Step-by-Step Guide

1. Mount the Shifters on the Handlebars
Start by positioning the Ergopower shifters on your handlebars. Ensure the brake levers are aligned to your preferred position for optimal ergonomics. Tighten the screws carefully to avoid overtightening, as this may damage the handlebar or shifters.

2. Install the Brake Cables
To install the brake cables, pass the cables through the respective slots on the shifters. Use a flathead screwdriver to adjust the brake tension if necessary. The cables should move freely but remain taut enough to provide quick braking response.

3. Install the Gear Cables
Next, run the gear cables from the shifters to the rear derailleur and front derailleur. Ensure that there is no slack and that the cables fit securely in their respective grooves. Once the cables are in place, use a torque wrench [paid link] to tighten the screws on the shifters. It’s essential to avoid over-tightening, as this could cause damage to the cable or shifter mechanism.

4. Adjust Cable Tension
Once installed, it’s time to adjust the cable tension for optimal shifting performance. Use the barrel adjuster to fine-tune the tension, making sure the derailleur moves freely without causing the chain to skip or over-shift.

5. Set Up the Battery and Wiring
The Athena EPS shifters require a battery for operation. Mount the battery on the frame or wherever it fits securely. Connect the battery to the wiring harness and ensure all connections are secure. The system should be ready to power up once everything is connected.


Adjusting the Athena EPS Ergopower Shifters

Fine-Tuning Shifting Performance

1. Calibrate the System
Once everything is installed, it’s important to calibrate the EPS system. Use the Campagnolo EPS software or the dedicated Athena EPS controller to set the derailleur positions. The system will automatically adjust the derailleur position and fine-tune shifting performance.

2. Fine-Tune the Front and Rear Derailleurs
After the initial calibration, check the performance of the front and rear derailleurs. If needed, adjust the position of the derailleurs using the micro-adjustment buttons on the shifters. This ensures the derailleur moves seamlessly between gears without hesitation or skipping.

3. Check Brake and Shifting Response
Test the braking and shifting response by riding the bike for a short distance. If the brakes feel soft or the shifts are sluggish, recheck the cable tension, derailleur positioning, and battery connection.


Maintaining the Athena EPS Ergopower Shifters

Regular Maintenance for Long-Term Performance

1. Clean the Shifters Regularly
To maintain smooth shifting performance, regularly clean the shifters using a soft cloth and mild soap solution. Avoid using harsh chemicals or water, as these could damage the sensitive components.

2. Lubricate Cables and Derailleurs
Lubrication is essential for keeping the cables and derailleurs functioning smoothly. Use a light bicycle-specific lubricant to prevent rust and friction buildup, and make sure to wipe off any excess to avoid attracting dirt.

3. Replace Cables as Needed
Cables can stretch over time and may need to be replaced every season or sooner depending on usage. When replacing cables, make sure to install fresh Campagnolo-compatible cables and adjust the tension accordingly.

4. Inspect the Battery
The EPS system relies on a battery, which should be checked regularly. Inspect the battery for corrosion or damage, and ensure it’s charged adequately for optimal performance. The battery should be replaced every 2-3 years depending on usage.


Troubleshooting Common Athena EPS Shifter Issues

Common Problems and How to Solve Them

1. Shifting Hesitation or Lag
If you notice hesitation or lag in shifting, the first thing to check is cable tension. If the cables are too loose or too tight, the shifters may not engage properly. Adjust the tension using the barrel adjuster on the shifter to ensure smooth, instant gear changes.

2. Sluggish Brake Response
If the brake levers feel sluggish or unresponsive, check the brake cables and ensure they’re properly installed and tightened. If the issue persists, it might be due to contamination or wear on the brake pads, requiring replacement or cleaning.

3. Front Derailleur Not Shifting Properly
Improper front shifting can often be traced to incorrect alignment or calibration. Make sure the front derailleur is properly positioned and calibrated through the EPS controller. If this doesn’t resolve the issue, inspect the derailleur hanger for damage or misalignment.


Conclusion

The Athena EPS Ergopower [paid link] shifters provide a superior electronic shifting experience that enhances your riding performance. By following the installation, adjustment, and maintenance procedures outlined in this guide, you can ensure that your shifters remain in optimal working condition for years to come.
