This precision-machined adapter allows you to mount a larger 180mm or 203mm brake rotor on a bicycle frame or fork that originally came with a 160mm post mount setup.

Larger rotors provide increased braking torque, better modulation, and improved heat management, giving you more control and confidence on every ride.

Upgrading to a larger rotor via this adapter offers tangible advantages:
Increased Stopping Power: Greater leverage from the larger rotor diameter results in stronger braking with less hand effort.

Reduced Brake Fade: The larger rotor surface area dissipates heat more effectively, maintaining consistent performance on long descents.

Improved Control: Enjoy better brake modulation and feel, especially under heavy load or in wet conditions.
