Tools Required [paid links]

Allen keys
Torque wrench (for precise tightening)
Bottom bracket tool [paid link] (specific to your BB type)
Bottom bracket grease
Clean rag and degreaser
Rubber mallet (if needed for removal)

Installing the Ekar 13s Crankset

Step 1: Preparing the Bottom Bracket

Before installing the crankset, ensure that your bottom bracket (BB) is properly installed and compatible with the Ekar 13s [paid link]. Campagnolo offers both Pro-Tech™ bottom brackets and other compatible options, depending on your frame type.

Clean the BB shell thoroughly using a rag and degreaser.
Apply a small amount of grease to the BB threads (if using a threaded BB) or press-fit cups.
Install the BB following Campagnolo’s specifications, ensuring it is torqued correctly.

Step 2: Installing the Crank Arms

Insert the drive-side crank arm (right crank arm) into the bottom bracket spindle. Ensure the Pro-Tech™ seal is correctly positioned to protect against dirt and moisture.
Slide the non-drive-side crank arm onto the spindle until it fits securely.
Insert the crank bolt and tighten it using an 8mm Allen wrench [paid link].
Use a torque wrench [paid link] to tighten the bolt to 42–46 Nm, ensuring the crank arms are securely fastened.

Step 3: Checking Alignment

Rotate the crankset several times to confirm smooth operation.
Check for any lateral play or unusual resistance. If the crank feels loose, double-check the bolt torque.

Adjusting the Ekar 13s Crankset

Proper adjustment ensures smooth power transfer and reduces wear on drivetrain components.

1. Checking for Lateral Play

Hold the crank arms and wiggle them side to side. If you feel movement, tighten the crank bolt slightly and recheck.

2. Chainring Alignment and Chain Retention

Ensure that the chainring is centered and does not wobble when pedaling.
If shifting feels sluggish, check the chainring bolts and torque them to 5–6 Nm.

3. Bottom Bracket Bearing Preload

The Campagnolo Ekar uses sealed Pro-Tech™ bearings, which do not require preload adjustments.
However, if you hear creaking or grinding noises, check the BB bearings for contamination.

Maintaining the Ekar 13s Crankset

Regular maintenance extends the life of your crankset and ensures consistent performance.

1. Cleaning Routine

Wipe down the crank arms and chainrings after every ride, especially in muddy or dusty conditions.
Use a mild degreaser to clean the chainrings and remove any buildup.

2. Lubrication

Lightly grease the crank bolt threads and bottom bracket interface every few months.
Do not apply excess grease on the carbon crank arms, as it can lead to contamination.

3. Inspecting for Wear and Damage

Check the chainrings for worn or bent teeth.
Inspect the carbon crank arms for cracks or delamination.
Replace worn chainrings as needed to maintain smooth shifting.

Troubleshooting Common Ekar 13s Crankset Issues

1. Creaking Noises While Pedaling

Cause: Loose crank bolt or contaminated bottom bracket bearings.
Solution: Retighten the crank bolt and clean/re-lubricate the BB bearings.

2. Chain Drops Frequently

Cause: Misaligned chainring or worn chainring teeth.
Solution: Check alignment and replace worn chainrings if necessary.

3. Difficulty Removing the Crankset

Cause: Dirt and grime buildup in the bottom bracket spindle.
Solution: Apply a small amount of penetrating oil and use a rubber mallet to gently loosen the crank arms.
