Compatibility & Fitment

• Fits most Road Bikes, Mountain Bikes (MTB), and BMX bikes equipped with 6-bolt disc brake hubs.
• Requires a disc brake caliper and frame/fork mount compatible with 180mm rotors. An adapter may be necessary for some setups.
• Compatible with major disc brake systems, including Shimano Alivio and Deore series.

When to Replace

• Rotor thickness measures below the minimum wear limit (typically stamped on the rotor, e.g., 1.5mm).
• Visible signs of significant warping, cracking, or deep scoring are present.
• Braking performance is diminished or feels inconsistent (pulsing).
• Persistent brake noise that cannot be resolved by cleaning, pad replacement, or caliper alignment.

Installation Tips

• Ensure hub mounting surface is clean and flat before installing.
• Tighten mounting bolts incrementally in a star pattern to the manufacturer's recommended torque specification.
• Clean the rotor surface with isopropyl alcohol after installation to remove any oils or contaminants.
• Properly bed-in new rotors with brake pads to achieve optimal braking performance.
• Check for proper caliper alignment and clearance after installation.
