FAQs

What is Ice Tech technology?

Ice Tech technology uses a 3-layer sandwich construction (stainless steel/alloy) to dissipate heat efficiently and reduce brake fade.

Do I need special tools to install this rotor?

You will need a Center Lock tool and a torque wrench for proper installation.

What kind of brake pads should I use?

For optimal performance, use Ice Tech brake pads with this rotor.

How often should I clean my rotors?

Clean your rotors regularly, especially after riding in wet or dirty conditions.

How do I check for rotor wear?

Check the rotor's thickness with a caliper. If it's below the minimum thickness specified by the manufacturer, it needs to be replaced.

What is the Center Lock system?

The Center Lock system is a Shimano-designed system for securing the rotor to the hub, providing a secure and reliable connection.

Can I use this rotor with any disc brake system?

It is compatible with a wide range of Shimano hydraulic disc brakes. Make sure your hub is Center Lock compatible.

Troubleshooting

Brakes are noisy.

Clean the rotor and brake pads with a disc brake cleaner. Check for contamination on the rotor or pads. Ensure the brake pads are properly aligned.

Brake fade during long descents.

Ensure you are using Ice Tech brake pads. Check the brake system for any air in the lines, and bleed the brakes if necessary. Consider upgrading to a larger rotor size if the problem persists.

Poor braking performance.

Check for any oil or grease contamination on the rotor. Inspect the brake pads for wear and replace if needed. Ensure the caliper is properly aligned and the rotor is true.

Rotor rubs against the brake pads.

Adjust the caliper alignment. Make sure the wheel is properly seated in the dropouts.
