Yes, it will function as a standard high-performance rotor, though the integrated magnet will simply remain unused.
No, this rotor requires a CENTER LOCK mounting interface.
The rotor includes the lockring which houses the integrated magnet for the speed sensor.
It significantly improves heat dissipation, preventing brake fade during long or heavy-duty braking sessions.
Use isopropyl alcohol for cleaning and ensure you do not touch the surface with bare, oily hands.
Ensure the rotor is properly centered and check that brake pads are not contaminated with oil.
Verify that the lockring magnet is correctly aligned with the sensor and that the lockring is tightened to the recommended torque.
Clean the braking surface with isopropyl alcohol to remove residue and verify that pads are bedded in correctly.
Installation requires a standard internal or external notch bottom bracket tool to secure the CENTER LOCK lockring. Always ensure your hub is CENTER LOCK compatible before purchase. For optimal performance, avoid using harsh degreasers on the rotor surface; clean only with isopropyl alcohol and a clean lint-free cloth. Regularly inspect the rotor for signs of warping and check the lockring torque to ensure the integrated magnet remains aligned with the STEPS speed sensor.
