The Campagnolo Record 12s Ergopower [paid link] shifters are high-performance components designed to deliver precise, smooth shifting on road bikes. Whether you’re upgrading your bike or replacing worn components, installing, adjusting, and maintaining these shifters properly will ensure you get the best performance out of your drivetrain.

This comprehensive guide will walk you through each step, from installation to regular maintenance, as well as troubleshooting common issues to keep your shifting as smooth as possible.

Tools Required

Before you begin the installation, adjustment, and maintenance of your Record 12s Ergopower [paid link] shifters, ensure you have the following tools on hand:

  • 2.5mm, 3mm, 4mm, and 5mm Allen wrenches [paid link]
  • Torque wrench [paid link]
  • Small flathead screwdriver
  • Cable cutters
  • Chain tool
  • Chain checker tool
  • Bike grease
  • 10mm spanner
  • Di2 tool (if installing electronic versions)
  • Lubricant (for cables and pivots)
  • Rag (for cleaning)

Installation of Record 12s Ergopower Shifters

Step 1: Prepare the Bike

Start by ensuring that your bike is stable on a repair stand. Remove any old shifters, cables, or housing from the handlebars if necessary.

Step 2: Install the Shifters on the Handlebars

  1. Position the Record 12s Ergopower [paid link] shifters on the handlebars. The left shifter is for the front derailleur, and the right shifter controls the rear derailleur.
  2. Slide the clamps of each shifter onto the handlebars in your desired position.
  3. Tighten the clamp bolts with a 5mm Allen wrench [paid link], ensuring that they are secure but not over-tightened. Typically, the recommended torque is between 6-8 Nm.

Step 3: Install the Brake Levers

The Record 12s [paid link] Ergopower combines brake and shifting functionality in a single lever. For installation, follow these steps:

  1. Attach the brake levers to the handlebars by sliding the mounting screws through the lever mounts.
  2. Tighten the screws using a 4mm Allen wrench [paid link] to the manufacturer’s recommended torque specification (approximately 6-8 Nm).
  3. Adjust the brake lever position, ensuring they are comfortably reachable when riding.

Step 4: Run the Cables

  1. Feed the shifting cables through the cable housing and into the shifter.
  2. Route the cables according to the manufacturer’s guidelines, ensuring they are free of kinks or tight bends that could hinder smooth movement.
  3. Connect the cables to the shifters and derailleur, securing them in place using the barrel adjusters or anchor bolts.

Adjustment of Record 12s Ergopower Shifters

Step 1: Front Derailleur Adjustment

  1. Set the Limit Screws: Adjust the front derailleur by setting the high and low limit screws to ensure the derailleur moves smoothly across all front chainrings.
    • Low screw: Ensures the derailleur doesn’t shift into the frame.
    • High screw: Prevents the derailleur from overshooting the outer chainring.
  2. Cable Tension: Use the barrel adjuster to fine-tune the cable tension, ensuring smooth shifting between chainrings.
    • For smoother shifting to the large chainring, reduce the tension.
    • For smoother shifting to the small chainring, increase tension.

Step 2: Rear Derailleur Adjustment

  1. Set the Limit Screws: Similar to the front derailleur, adjust the rear derailleur’s high and low limit screws to prevent the chain from overshooting the cassette.
    • Low screw: Ensures the derailleur doesn’t push the chain beyond the smallest cog.
    • High screw: Ensures the derailleur doesn’t push the chain past the largest cog.
  2. Cable Tension: Adjust the cable tension using the barrel adjuster. For better shifting performance, fine-tune the tension until the derailleur moves cleanly across the entire cassette.

Step 3: Fine-Tuning

Test the shifting by moving through all the gears on both the front and rear. Make minor adjustments as needed:

  • If shifts are hesitant or miss a gear, fine-tune the barrel adjuster.
  • If shifting is too stiff or sloppy, adjust the cable tension to ensure smooth engagement with each gear.

Maintenance of Record 12s Ergopower Shifters

Cleaning the Shifters

Over time, dirt and grime can accumulate around the Ergopower shifters, impacting their performance. To clean the shifters:

  1. Wipe down the exterior of the shifters with a rag.
  2. Use a small brush to remove dirt from hard-to-reach places.
  3. Ensure the brake lever pivots are clean and lubricated to maintain smooth operation.

Lubricating the Cables

Regular lubrication of your cables will keep shifting smooth and prevent wear:

  1. Use a lubricant specifically designed for cables.
  2. Apply lubricant to both the inner cables and the exterior of the cable housing.
  3. Rotate the shifters through their range of motion to ensure the lubricant is evenly distributed.

Inspecting the Cables and Housing

Check the cables and housing for any signs of wear or damage. Replace any frayed or damaged cables immediately to prevent poor shifting performance. Ensure the housing is clean and free from kinks or bends.

Check for Friction and Wear

Regularly check the shifter mechanism for any signs of friction. The internal parts should move freely when the shifter is engaged. If the movement feels stiff or rough, apply lubricant to the moving parts or disassemble the shifters for deeper maintenance.

Troubleshooting Common Issues

Problem 1: Shifting Is Hesitant or Misses Gears

If you notice that the shifters are hesitant or skip gears, the most likely issue is cable tension. Adjust the barrel adjuster to either increase or decrease the tension.

Problem 2: Sticky or Unresponsive Shifter

If the Ergopower shifter feels sticky, it could be due to dirty or dry cables, or worn internal components. Clean the shifters and cables and apply fresh lubricant.

Problem 3: Brake or Shift Levers Not Returning

If the brake or shift levers don’t return to their original position after use, it could indicate an issue with the internal spring or friction in the shifter mechanism. In this case, disassemble the shifter and check the spring tension and lubrication.

Record 12s Ergopower vs. Shimano 105: Key Differences

While both the Campagnolo Record 12s [paid link] Ergopower and Shimano 105 offer excellent shifting performance, there are notable differences:

  • Weight: The Record 12s [paid link] is lighter than the Shimano 105.
  • Shifting Action: Campagnolo’s Ergopower offers a unique “one lever, one action” shifting design, which some riders find more intuitive.
  • Ergonomics: Campagnolo has a distinct ergonomic shape that some riders prefer, while Shimano is known for its more straightforward design.

Ultimately, the choice comes down to personal preference and compatibility with your bike’s drivetrain.

Record 12s Ergopower Shifter Compatibility

The Record 12s Ergopower shifters are designed for Campagnolo’s 12-speed drivetrains. They may not be directly compatible with Shimano or SRAM drivetrains without the use of additional adapters. When selecting components for your bike, ensure that your derailleur, cassette, and chain are also designed for 12-speed Campagnolo drivetrains to guarantee optimal performance.

Conclusion

The Campagnolo Record 12s Ergopower shifters are a premium choice for cyclists who demand top-tier performance and precision. Installing, adjusting, and maintaining these shifters correctly will ensure that you enjoy smooth, reliable shifting for many miles. With the right care and attention, these shifters will provide optimal performance and last for years.
