The Campagnolo Ekar 13s crankset [paid link] is an exceptional component designed for gravel and off-road riders who demand durability, reliability, and performance. However, improper installation can lead to issues that not only affect your bike’s performance but also its longevity. In this guide, we will walk through common installation mistakes and how to avoid them, ensuring your Ekar 13s crankset [paid link] operates at its best.

Tools Required

• Crankset tool or bottom bracket tool [paid link] (specific to your bottom bracket)
• 8mm hex wrench
• Torque wrench [paid link] (set to the recommended torque value for crank bolts)
• Grease
• Clean rag or towel
• Crank arm extractor (if necessary)
• Anti-seize compound (optional)

Mistake 1: Incorrect Bottom Bracket Installation

The Ekar 13s [paid link] crankset is designed to fit with a specific bottom bracket type. Using an incompatible bottom bracket or misinstalling it can lead to poor crankset performance, excessive wear, and instability.

How to Avoid It:

• Ensure the bottom bracket is compatible with the Ekar 13s [paid link] crankset. Campagnolo uses its own specific design for its gravel cranksets.
• Always follow the installation instructions for the bottom bracket type recommended by Campagnolo.
• Apply a thin layer of grease to the bottom bracket threads to ensure smooth installation and prevent creaking or corrosion.

Mistake 2: Over-tightening or Under-tightening Crank Arm Bolts

Crank arm bolts play a crucial role in securing the crankset to the bottom bracket. Over-tightening can damage the crank arms or bottom bracket, while under-tightening can lead to the cranks loosening during rides, resulting in a dangerous situation.

How to Avoid It:

• Use a torque wrench [paid link] to tighten the crank arm bolts to the manufacturer’s recommended torque value. For the Ekar 13s, this is typically around 40-50Nm.
• Double-check that the bolts are evenly tightened to avoid uneven force distribution.

Mistake 3: Failure to Lubricate the Crankset Spindle

The Ekar 13s crankset is equipped with a high-quality spindle that ensures smooth pedal movement. Failing to properly lubricate the spindle can lead to premature wear, squeaks, and poor power transfer.

How to Avoid It:

• Apply a thin layer of grease to the spindle before installing the crank arms.
• Do not use too much grease, as excess lubricant can attract dirt and grime, causing additional friction.

Mistake 4: Not Installing the Crank Arms Correctly

The Ekar 13s crankset features a direct-mount design, and it’s crucial that the crank arms are installed correctly to ensure proper alignment and function.

How to Avoid It:

• Align the crank arm with the spindle using the manufacturer’s indicated marks.
• Confirm the left crank arm is mounted on the non-drive side and the right crank arm on the drive side.
• Ensure both arms are fully seated on the spindle before tightening the bolts.

Mistake 5: Ignoring Pedal Installation Torque

The pedals are often overlooked during crankset installation, but if they are not properly installed, they can cause instability and damage to the threads on the crank arms.

How to Avoid It:

• Ensure the pedals are installed on the correct side of the crank arms. The right pedal goes on the right crank arm (clockwise) and the left pedal goes on the left crank arm (counter-clockwise).
• Tighten the pedals to the correct torque, generally around 35-40Nm, using a torque wrench.

Mistake 6: Skipping the Crankset Alignment Check

Misaligned crank arms can cause problems in both performance and comfort. Riding with unevenly installed crank arms leads to inefficient power transfer and can cause knee pain over time.

How to Avoid It:

• Check for crank arm alignment using a dedicated tool or by comparing both crank arms visually. They should be perfectly aligned with the bike’s frame.
• Verify that the crank arms are positioned symmetrically to ensure balanced performance.

Mistake 7: Using Old or Worn-out Crankset Hardware

Reusing old or worn-out hardware, such as bolts and washers, may seem cost-effective, but it can cause issues with securing the crankset properly, leading to failure over time.

How to Avoid It:

• Always replace bolts and washers when installing a new crankset.
• Inspect all hardware for signs of wear or corrosion before reusing them. If necessary, replace them with genuine Campagnolo parts.

Mistake 8: Not Checking for Crankset Play After Installation

It’s important to check for any movement or play in the crankset once installation is complete. Any play can indicate improper installation and will affect performance.

How to Avoid It:

• After installation, rotate the cranks by hand and check for any wobble or play.
• If you notice any movement, recheck the crank arm bolts and ensure they are tightened to the correct torque value.

Mistake 9: Failing to Verify Chainline Alignment

The chainline is crucial for efficient pedaling and drivetrain performance. Installing the crankset incorrectly can misalign the chainline, causing poor shifting performance and excessive wear on the drivetrain components.

How to Avoid It:

• Verify that the crankset is installed with the correct chainline for your specific bike setup.
• Make sure the chainring is aligned with the cassette and chain when the crankset is installed.

Mistake 10: Skipping a Final Check for Secure Installation

Once everything is installed, it’s easy to rush through the process and overlook a final check for tightness and alignment.

How to Avoid It:

• Double-check all bolts, including crank arm bolts, pedal bolts, and bottom bracket fasteners.
• Ensure everything is tight, aligned, and torqued according to Campagnolo’s specifications.

Conclusion

By avoiding these common installation mistakes, you can ensure that your Campagnolo Ekar 13s crankset performs optimally from the start. Proper installation not only prevents issues like loose crank arms or misaligned pedals but also extends the life of your components, keeping your ride smooth and reliable for many miles to come. Always follow the manufacturer’s guidelines, use the correct tools, and perform regular checks to keep your bike in top condition.
