What is the bolt circle size for this rotor?

This Alcon Pro-System rotor has an 8x7 inch bolt circle. This specific pattern is designed to match Alcon caliper mounting requirements.

What do the S-Grooves do?

The S-Grooves on the rotor surface help to sweep away dust and gas that builds up between the brake pad and rotor. This keeps the pad surface cleaner and allows for more consistent friction during braking.

Is this rotor sold individually?

Yes, this part number is for a single rotor designed for the right side of the vehicle. If you need a set, you will need to order two and ensure you get the correct left and right side rotors.
