The Campagnolo Super Record EPS 11s Crankset [paid link] is renowned for its precision, durability, and performance. However, like any high-performance component, it is not immune to issues. Understanding and troubleshooting common problems associated with the Super Record EPS 11s Crankset [paid link] can help ensure that your ride remains smooth and efficient. This guide covers the most common problems you might encounter with your Super Record EPS 11s Crankset [paid link], along with solutions to resolve them.

1. Crankset Creaking or Noisy Pedals

A creaky or noisy crankset is one of the most frequent complaints from riders. This issue is typically caused by improper installation, insufficient lubrication, or wear in the bottom bracket or crank arms.

Causes:

  • Lack of lubrication on the crankset or pedal threads.
  • Loose crank arm bolts or pedal attachment.
  • Wear and tear on the bottom bracket bearings.

Solutions:

  • Ensure that both the pedal threads and the crank arm bolts are properly lubricated to prevent friction, which could lead to creaking.
  • Tighten the crank arm bolts to the manufacturer’s specified torque (12-14 Nm for Super Record EPS 11s [paid link]).
  • Inspect the bottom bracket for signs of wear or damage. If necessary, replace the bottom bracket to eliminate any play or unwanted noise.

2. Crankset Feels Loose or Unstable

A loose or unstable crankset can negatively affect your pedaling efficiency, leading to poor power transfer and an uncomfortable ride. This issue is usually related to improper tightening of the crankset bolts or a faulty bottom bracket.

Causes:

  • Under-tightened crank arm bolts.
  • Bottom bracket not properly installed or damaged.

Solutions:

  • Always check the torque specifications for the crank arm bolts (12-14 Nm). Use a torque wrench [paid link] to ensure the bolts are tightened correctly.
  • Inspect the bottom bracket to ensure it is properly installed and secured. If the bottom bracket feels loose or worn, replace it with a new one.

3. Chain Dropping or Skipping

Chain dropping or skipping can happen if the chainrings are misaligned or there is an issue with the front derailleur setup. These issues are common when the crankset has been improperly adjusted or the drivetrain has been poorly maintained.

Causes:

  • Misalignment of the chainrings.
  • Incorrect front derailleur adjustment.
  • Worn-out chain or chainrings.

Solutions:

  • Check the alignment of the chainrings with the bike’s frame. The chainrings should be centered, and the teeth should not show significant wear.
  • Re-adjust the front derailleur so that it shifts smoothly across the entire gear range.
  • Inspect the chain for signs of elongation and replace it if necessary. A worn-out chain can cause poor shifting and contribute to chain skipping.

4. Difficulty Shifting Under Load

Shifting difficulties, especially under load, are a common issue with electronic drivetrains. These issues can stem from improper calibration of the EPS system, worn-out cables, or drivetrain misalignment.

Causes:

  • Poor electronic shift calibration.
  • Chainring or cassette misalignment.
  • Insufficient battery charge for the EPS system.

Solutions:

  • Check and calibrate the EPS system using the Campagnolo EPS interface. Ensure that the system is properly adjusted and shifting smoothly.
  • Inspect the chainring and cassette for proper alignment. Misalignment can cause difficulty shifting under load.
  • Make sure that the EPS battery is fully charged. Low battery levels can cause delayed or erratic shifting.

5. Wobbly Crankset

A wobbly crankset can be caused by several factors, including improper installation or the degradation of components like the crankset bolts, bottom bracket, or crank arms themselves.

Causes:

  • Loose or worn crank arm bolts.
  • Worn-out bottom bracket.
  • Crank arm damage.

Solutions:

  • Tighten the crank arm bolts to the manufacturer’s recommended torque setting (12-14 Nm).
  • Inspect the bottom bracket for any signs of damage or looseness. A damaged bottom bracket should be replaced immediately to restore stability.
  • Check the crank arms for any signs of damage, such as cracks or wear. If the crank arms are damaged, replace them to avoid further issues.

6. Crankset Resistance When Pedaling

If you feel resistance when pedaling, it could be due to improper lubrication, too-tight chainring bolts, or a bottom bracket that is starting to seize.

Causes:

  • Over-tightened chainring bolts.
  • Lack of lubrication on the crankset.
  • Worn or damaged bottom bracket bearings.

Solutions:

  • Ensure the chainring bolts are not over-tightened. The recommended torque for these bolts is 10-12 Nm.
  • Lubricate the crankset’s spindle and pedal threads to ensure smooth pedaling.
  • Inspect the bottom bracket bearings for any resistance when rotating. If the bottom bracket feels rough or stiff, replace it with a new one to restore smooth pedaling.

7. Pedal Thread Stripping

Stripped pedal threads can occur when the pedals are not properly installed, or excessive force is applied when attaching the pedals. This issue is more common with aluminum cranksets but can affect any crankset model.

Causes:

  • Cross-threading the pedals during installation.
  • Applying too much force when installing the pedals.

Solutions:

  • Always thread the pedals by hand first to avoid cross-threading.
  • Use the correct size pedal wrench [paid link] to tighten the pedals to the proper torque (35-40 Nm).
  • If the threads are already stripped, you may need to replace the crankset or use a pedal thread repair kit if the damage is minor.

8. Chainline Issues

A misaligned chainline can cause poor drivetrain performance, especially when shifting under load or during hard efforts. This issue can often be traced back to an improper crankset installation or misalignment with the cassette and chainring.

Causes:

  • Improper crankset installation or bottom bracket misalignment.
  • Use of incompatible chainrings or bottom bracket.

Solutions:

  • Verify that the crankset is properly installed, ensuring it is aligned with the bike’s bottom bracket and chainring.
  • If using aftermarket chainrings, ensure they are compatible with the Super Record EPS 11s crankset [paid link].
  • Check the chainring for wear and replace it if necessary.
