Campagnolo’s Ekar AFS Disc Rotors [paid link] are designed for high-performance braking on gravel and road bikes. These rotors utilize the AFS (Axial Fixing System) standard, ensuring strong and consistent braking performance. To get the most out of your Ekar rotors, proper installation, adjustment, and routine maintenance are essential.
This guide covers everything from setup to long-term care, helping you maximize braking efficiency and longevity.
Tools Required
- T25 Torx wrench [paid link]
- Torque wrench [paid link] (with Nm settings)
- Isopropyl alcohol or disc brake cleaner
- Clean, lint-free cloth
- Rubber gloves (to avoid contaminating rotors)
- 6-bolt adapter [paid link] (if using non-Centerlock hubs)
- Shimano TL-FC36 [paid link] or similar lockring tool [paid link] (for Centerlock)
Step-by-Step Installation of Ekar AFS Disc Rotors
1. Preparing the Rotor and Hub
Before installing the rotor, clean it with isopropyl alcohol or a dedicated disc brake cleaner. This removes manufacturing residues or contaminants that can affect braking performance.
If using a Centerlock system, ensure the hub’s spline interface is clean and free of debris. For 6-bolt setups, check that the adapter (if needed) is securely mounted.
2. Installing the Rotor on a Centerlock Hub
- Align the rotor’s AFS pattern with the hub’s splines.
- Press the rotor onto the hub and install the Centerlock lockring.
- Use a Shimano TL-FC36 [paid link] or equivalent lockring tool [paid link] to tighten the lockring to 40 Nm.
3. Installing the Rotor on a 6-Bolt Hub
- Place the rotor onto the hub’s mounting interface, ensuring the directional arrow matches the wheel’s rotation.
- Secure the rotor using the T25 Torx bolts in a star pattern.
- Torque each bolt to 6 Nm to prevent uneven stress.
Adjusting the Ekar AFS Disc Rotors for Optimal Performance
Once installed, the rotor should run true within the brake caliper. Any slight misalignment can cause brake rub or uneven braking force.
1. Checking Rotor Alignment
- Spin the wheel and observe any lateral movement of the rotor.
- If it wobbles, gently straighten minor bends using a rotor truing tool.
2. Adjusting the Brake Caliper
- Loosen the caliper mounting bolts slightly.
- Squeeze the brake lever and hold it to center the caliper.
- While holding the lever, tighten the mounting bolts evenly.
- Spin the wheel to check for rubbing.
If the rotor still rubs, fine-tune the caliper positioning by loosening and realigning it manually.
Routine Maintenance for Ekar AFS Disc Rotors
Regular maintenance prevents braking power loss and extends the life of your rotors.
1. Cleaning the Rotors
- Wipe down the rotors weekly using isopropyl alcohol and a clean cloth.
- Avoid using oil-based cleaners or touching the rotor surface with bare hands.
2. Inspecting for Wear and Damage
- Measure the rotor thickness using a caliper. Replace at 1.5mm thickness (original is 1.8mm).
- Look for deep grooves, warping, or cracks. Replace if damaged to maintain safe braking.
3. Preventing Contamination
- Never spray lubricants or degreasers near the rotors.
- Store bikes away from chemical exposure that could contaminate braking surfaces.
Troubleshooting Common Issues with Ekar AFS Disc Rotors
1. Brake Rub After Installation
- Solution: Loosen the caliper bolts, reset the position, and tighten evenly.
2. Squealing or Noisy Brakes
- Solution: Clean the rotor and pads with isopropyl alcohol. Ensure pads are bedded in properly.
3. Pulsating Brakes or Vibration
- Solution: Check for uneven rotor wear. If grooved, resurface with fine sandpaper or replace.
4. Weak Braking Power
- Solution: Confirm pads are not contaminated, bed them in properly, and check rotor thickness.
Comparing Ekar AFS Disc Rotors to Other Models
The Ekar AFS Disc Rotors [paid link] offer excellent heat dissipation and braking consistency, making them a top choice for gravel riders. Compared to Shimano’s Ice-Tech or SRAM’s Centerline X [paid link] rotors:
| Feature | Ekar AFS Rotors | Shimano Ice-Tech | SRAM Centerline X [paid link] |
|---|---|---|---|
| Material | Stainless steel | Aluminum & steel | Stainless steel |
| Heat Dissipation | Moderate | High | Moderate |
| Weight | Light | Medium | Light |
| Mounting System | AFS (Centerlock) | Centerlock & 6-bolt | Centerlock & 6-bolt |
Verdict: If you ride on gravel and need reliable braking with easy maintenance, Ekar AFS is a strong choice.
Final Thoughts
Proper installation, adjustment, and routine maintenance ensure your Ekar AFS Disc Rotors [paid link] perform at their best. Keeping them clean, aligned, and free of contamination will extend their lifespan and enhance your braking control.
