Freedom Coast Post Mount Disc Brake Adapter Precision machined. USA-made. Built to actually fit. Cast aluminum brake adapters are a cost-cutting measure, and the tolerances show - pad rub, alignment headaches, and finicky installs are the result. Freedom Coast's post mount disc brake adapters are CNC-machined from aerospace-grade 6061 aluminum to a much tighter flatness tolerance, keeping brake pads perfectly parallel to the rotor and eliminating the pad contact issues common with stock cast adapters. A 4-bolt design uses four equal-length titanium bolts from Better Bolts, ditching the cup and cone washers that make standard adapter installations a hassle. Available in four sizes to accommodate 160mm and 180mm post mount forks and frames, in eight adapter colors with five titanium bolt color options. Made in the USA.
