Specifically engineered for 140mm rotors, this adapter ensures proper caliper alignment and optimal pad-to-rotor contact for reliable braking performance.

Precision-machined from high-strength aluminum, this lightweight component maintains a stiff interface to prevent brake rub and noise. It is an essential part for riders looking to use their favorite Post Mount calipers on modern Flat Mount road, gravel, or cross frames.
