The Campagnolo Super Record EPS 11s Crankset [paid link] is known for its exceptional performance and durability. However, like any high-performance component, it requires maintenance to keep it operating at peak efficiency. One of the key areas to focus on is the crankset’s bearings. Proper maintenance and timely replacement of the bearings are essential for maintaining smooth, efficient power transfer and avoiding unnecessary wear on the drivetrain. In this guide, we’ll take you through the process of replacing and servicing the bearings in your Super Record EPS 11s Crankset [paid link].

Tools Required

• Campagnolo Super Record EPS 11s Crankset [paid link] bearing tool
• 10mm socket wrench
• Torque wrench [paid link]
• Bearing puller tool
• New bearings (Campagnolo Super Record EPS 11s [paid link] compatible)
• Cleaning brush
• Grease (specifically designed for bicycle cranksets)
• Cotton rags or clean towels
• Crankset extractor tool (if needed)
• Isopropyl alcohol or degreaser

Preparation: Removing the Crankset

Before servicing or replacing the bearings, the crankset must be removed from the bike. If you’re unfamiliar with the process, here’s a quick rundown of the necessary steps:

1. Shift Gears: Shift your bike to the smallest chainring to reduce tension on the crankset.
2. Remove Pedals: Use a pedal wrench [paid link] or 15mm spanner to remove the pedals from the crankset.
3. Loosen Crankset Bolts: Use a 10mm socket wrench to remove the crankset bolts. These are typically located on both the drive side and non-drive side of the bike.
4. Extract the Crankset: If necessary, use a crankset extractor tool to remove the crankarms from the bottom bracket. This step may vary depending on whether your bike uses a standard or press-fit bottom bracket system.

Once the crankset is removed, you’ll have full access to the bearings.

Step 1: Inspect the Bearings

Before you proceed with bearing replacement, it’s crucial to inspect the current bearings for signs of wear or damage. Here’s what to look for:

• Excessive Play: If you can feel excessive lateral movement when gently wiggling the crankset, it’s likely that the bearings are worn out.
• Noise: A grinding or squeaking noise during pedaling is often a sign of damaged bearings.
• Smoothness: Spin the bearings by hand. They should rotate smoothly and without resistance. If you feel roughness or stuttering, replacement is necessary.

Step 2: Removing the Old Bearings

Once you’ve determined that the bearings need replacing, you can move on to their removal. The Super Record EPS 11s crankset [paid link] is equipped with high-precision bearings, and the removal process requires the correct tools to avoid damaging the crankset.

1. Locate the Bearings: The bearings are located at the bottom of the crankset arms, seated within the bearing cups.
2. Use the Bearing Puller: Using a bearing puller tool, carefully extract the bearings from their housing. Ensure the puller tool is properly aligned with the bearing to avoid damaging the surrounding area.
3. Clean the Area: After the bearings are removed, thoroughly clean the crankset area. Use a cleaning brush to remove any dirt, grease, or old lubricant. Wipe the area with a cotton rag, and use isopropyl alcohol or degreaser to ensure it is free of contaminants.

Step 3: Installing the New Bearings

With the old bearings removed, you can now proceed with installing the new ones. Campagnolo recommends using only compatible bearings to ensure the longevity and performance of the crankset.

1. Grease the Bearing Seats: Apply a light layer of grease to the bearing seats in the crankset. This will help prevent corrosion and ensure that the new bearings slide in smoothly.
2. Insert the New Bearings: Using your bearing press [paid link] tool, carefully press the new bearings into the crankset. Be sure the bearings are seated properly within their housing. Apply even pressure to avoid damaging the bearings or the crankset itself.
3. Check for Smooth Rotation: Once installed, rotate the bearings by hand to make sure they spin smoothly without resistance. If they feel stiff or rough, it may indicate they were not properly installed.

Step 4: Reassembling the Crankset

Once the bearings are installed, it’s time to reassemble the crankset:

1. Reinstall the Crankset: Slide the crankset back onto the bottom bracket spindle. Align the crankset arms with the correct position (the pedal arms should be pointing outward).
2. Tighten the Bolts: Use your torque wrench [paid link] to tighten the crankset bolts to the manufacturer’s recommended torque specifications. This ensures that the crankset is secure without over-tightening.
3. Reinstall Pedals: Reinstall the pedals onto the crankset arms and tighten them to the correct torque.

Step 5: Testing and Final Adjustments

After reassembling the crankset, it’s important to test the bike to ensure everything is functioning correctly:

1. Spin the Crankset: Turn the crankset by hand to ensure smooth rotation and check for any wobble or abnormal resistance.
2. Test Ride: Go for a short test ride to ensure there are no noises, vibrations, or issues with power transfer. Listen for any unusual sounds and feel for any abnormal movement in the crankset.
3. Recheck Bolt Tightness: After the test ride, double-check the crankset bolts to ensure they are still properly torqued.

Maintenance Tips for Extending Bearing Life

To ensure the longevity of your new bearings, follow these maintenance tips:

• Regular Cleaning: Keep your crankset clean by regularly wiping down the crankarms and ensuring that no dirt or debris gets into the bearing area.
• Lubrication: Apply the appropriate lubrication to the crankset and bearing areas during routine maintenance to reduce friction and prolong the life of the bearings.
• Periodic Inspections: Regularly inspect the crankset and bearings for any signs of wear or damage. Catching issues early can prevent more significant damage down the line.

Conclusion

Replacing or servicing the bearings in your Campagnolo Super Record EPS 11s Crankset [paid link] is a straightforward process that can significantly improve the performance and longevity of your bike. By following these steps and using the correct tools, you’ll ensure smooth and efficient power transfer during every ride. Regular maintenance and timely replacement of the bearings will keep your crankset performing like new for years to come.
