When cycling, a noisy or creaky crankset can be a major annoyance, affecting both performance and comfort. The Campagnolo Record EPS 11s Crankset [paid link], known for its precision and durability, is no exception to this issue. However, identifying the root cause and resolving the noise is often a simple task with the right knowledge and approach. In this guide, we’ll walk you through diagnosing and fixing common creaking or clicking noises associated with your Campagnolo Record EPS 11s Crankset [paid link].

Common Causes of Noises and Creaks

Before diving into the troubleshooting process, it’s essential to understand some of the most common reasons behind crankset noise:

  • Loose or poorly installed crank arm bolts
  • Worn out bottom bracket bearings
  • Improperly torqued chainring bolts
  • Lack of lubrication on key moving parts
  • Wear or damage to the crank arms or bottom bracket interface
  • Crankset misalignment or incorrect installation

Once you know what to look for, you can narrow down the possible causes of your crankset noise.

Step 1: Tighten Crank Arm Bolts

A very common source of creaking noises comes from loose crank arm bolts. The Campagnolo Record EPS 11s Crankset [paid link] uses a unique interface between the crank arms and the bottom bracket spindle, requiring precise torque for optimal performance.

How to Tighten Crank Arm Bolts:

  1. Use a Torque Wrench [paid link]: Set your torque wrench [paid link] to 40 Nm, which is the recommended torque for the crank arm bolts.
  2. Tighten the Left and Right Crank Arm Bolts: Start by tightening the left crank arm bolt. Once it’s secure, move on to the right side. Make sure both bolts are equally tightened to prevent uneven stress on the crankset.
  3. Double-Check the Torque: It’s important to re-check the torque after a short ride, as bolts can sometimes loosen slightly with the initial use.

Step 2: Inspect Bottom Bracket Bearings

The bottom bracket plays a critical role in the smooth operation of the crankset. Over time, the bearings inside the bottom bracket can wear out or become contaminated, leading to a creaky sound as the crankset turns. The Campagnolo Record EPS 11s [paid link] Crankset requires a compatible bottom bracket, which should be inspected for wear or damage.

How to Inspect and Replace Bottom Bracket Bearings:

  1. Remove the Crankset: Use a crank puller tool to remove the crankset from the bottom bracket spindle.
  2. Check the Bearings: Inspect the bottom bracket bearings for any roughness or play. You can check this by manually spinning the bottom bracket spindle and feeling for any resistance or irregular movement.
  3. Replace the Bearings: If the bearings are rough or worn out, replace them with new Campagnolo-compatible bottom bracket bearings. Ensure the new bearings are properly greased before installation.
  4. Reinstall the Crankset: Once the bearings are replaced, reinstall the crankset and tighten the crank arm bolts to the proper torque.

Step 3: Check Chainring Bolts

If the chainring bolts are not correctly tightened or if they’ve become worn over time, they can also produce a creaking sound. The chainring bolts on the Campagnolo Record EPS 11s [paid link] Crankset should be evenly tightened to ensure that the chainring is securely attached.

How to Tighten Chainring Bolts:

  1. Use a Torque Wrench [paid link]: Set the torque wrench to 12 Nm, the recommended torque for Campagnolo chainring bolts.
  2. Tighten Each Bolt in a Star Pattern: To ensure even pressure on the chainring, tighten the bolts in a star or crisscross pattern, alternating between opposite bolts.
  3. Re-check the Bolts After a Ride: Check the bolts after your next ride to ensure they remain tight and haven’t loosened.

Step 4: Lubricate Moving Parts

Creaking noises often come from dry or improperly lubricated parts. This includes the crankset interface, bottom bracket, and the chainring bolts. Lack of lubrication increases friction, causing noise and wear.

How to Lubricate:

  1. Clean the Components: Before applying any lubrication, clean the crankset interface, chainring bolts, and bottom bracket with a degreaser to remove any dirt or old grease.
  2. Apply Lubricant: Apply a thin layer of grease to the bottom bracket spindle interface, chainring bolts, and crank arm interface. Use a high-quality bike-specific grease that will resist water and dirt buildup.
  3. Reinstall and Tighten: After lubricating, reinstall the crankset and tighten the components as per the specified torque settings.

Step 5: Inspect Crankset and Chainring Alignment

If the crankset is not aligned correctly or if the chainring is slightly bent, it can cause uneven wear and creaking noises. Ensure that the crankset is properly installed and that the chainring teeth are not damaged.

How to Check and Adjust Alignment:

  1. Visual Inspection: Look for any visible damage or misalignment between the crank arms and the chainring. If the chainring is bent, it can lead to uneven pedaling forces and creaks.
  2. Check for Play: Spin the crankset by hand and check for any play or wobble in the crank arms or bottom bracket spindle. Any movement indicates a misalignment or a loose component.
  3. Align and Reinstall: If necessary, align the crankset and chainring properly, ensuring that all bolts are tightened to the correct torque.

Step 6: Test Ride and Final Adjustments

Once all potential sources of noise have been addressed, it’s time for a test ride. Pay attention to any lingering creaking sounds while cycling, especially during pedaling efforts. If you still hear creaks, recheck each step, starting from the crank arm bolts to the bottom bracket.

What to Look For:

  • Smooth Pedaling: Ensure that there’s no resistance or jerking when pedaling.
  • Silence Under Load: Pay special attention to whether the creaking noise occurs during higher pedaling loads or steady cadences.

Conclusion

Creaking or noisy cranksets, particularly with a high-performance model like the Campagnolo Record EPS 11s [paid link] Crankset, can disrupt your ride, but they’re often easy to fix with a little maintenance. By systematically tightening bolts, inspecting bearings, lubricating moving parts, and ensuring proper alignment, you can eliminate these unwanted noises. Keep your crankset clean and well-maintained, and it will continue to perform optimally for many miles to come.
