When to Replace

• Rotor surface is worn below the manufacturer's minimum thickness specification.
• Visible signs of damage, such as warping, deep grooves, or cracks.
• Persistent braking vibration or pulsing that is not resolved by other adjustments.
• Braking performance is significantly reduced.

Installation Tips

• Clean the rotor and hub mounting surface with isopropyl alcohol before installation to remove contaminants.
• Install the rotor following any directional arrows indicating the direction of wheel rotation.
• Tighten the mounting bolts sequentially in a star pattern to the torque specified by the hub or bicycle manufacturer.
• Ensure the brake caliper is correctly aligned with the new rotor to prevent rubbing.
• Install new brake pads when replacing a rotor to ensure proper bedding-in and optimal performance.
