- Remove the rear wheel.
- Clean the derailleur hanger with isopropyl alcohol to remove any debris.
- Use a derailleur hanger alignment tool to check and correct any misalignment.
2. Mounting the Rear Derailleur
- Align the derailleur mounting bolt with the hanger threads.
- Secure the derailleur using a 5mm Allen wrench [paid link] and tighten it to 8–10 Nm using a torque wrench [paid link].
- Ensure the B-screw (hanger contact adjustment screw) is in the default position before proceeding.
3. Connecting the EPS Electronic Wires
The Super Record EPS 11s [paid link] rear derailleur connects to the EPS system via waterproof electronic cables.
- Connect the derailleur cable to the EPS Power Unit (interface box).
- Ensure the cable is fully inserted and seated correctly.
- Use the MyCampy app or EPS V4 Interface Unit to check connectivity.
4. Installing the Chain
- Route the chain through the upper and lower jockey wheels correctly.
- Use a Campagnolo 11-speed chain and connect it with a Campagnolo Ultra-Link.
- Ensure correct chain tension by checking that the derailleur moves freely through its range.
5. Testing Initial Functionality
- Power on the EPS system and shift through gears.
- Listen for excessive noise or resistance, which may indicate misalignment.
Adjusting the Super Record EPS 11s Rear Derailleur
Once installed, fine-tuning the derailleur ensures smooth shifting.
1. Setting the Limit Screws
The Super Record EPS 11s [paid link] has two limit screws:
- H (High Gear) Screw – Sets the limit for the smallest cog.
- L (Low Gear) Screw – Sets the limit for the largest cog.
- High Gear Limit Adjustment:
- Shift into the smallest cog.
- Adjust the H screw until the jockey wheel is directly in line with the cog.
- Low Gear Limit Adjustment:
- Shift into the largest cog.
- Adjust the L screw so the derailleur does not overshift past the last cog.
2. Indexing the Shifting
EPS derailleurs self-adjust, but fine-tuning may be needed.
- Use the EPS Micro-Adjust Mode to fine-tune shifts.
- Shift through the entire cassette and adjust if shifts feel sluggish.
- Use the MyCampy app to update firmware if needed.
Maintaining the Super Record EPS 11s Rear Derailleur
Regular maintenance extends the lifespan of the Super Record EPS 11s [paid link] and ensures top performance.
1. Cleaning the Derailleur
- Use isopropyl alcohol to clean jockey wheels and derailleur pivots.
- Avoid pressure washers, which may damage electronic components.
2. Checking the Battery and Connections
- Ensure EPS battery is fully charged.
- Inspect electronic connectors for corrosion or dirt buildup.
3. Inspecting and Lubricating the Chain
- Use Campagnolo-approved chain lube to prevent wear.
- Check for chain wear every 2,000–3,000 km and replace if stretched.
Troubleshooting Common Issues
1. Slow or Unresponsive Shifting
- Issue: Rear derailleur hesitates or does not shift.
- Solution: Check the battery charge and re-sync the EPS system via the MyCampy app.
2. Clicking or Noisy Shifting
- Issue: Chain rubs or makes excessive noise.
- Solution: Use Micro-Adjust Mode to fine-tune indexing.
3. EPS Rear Derailleur Not Responding
