You've just bought a beautiful new disc-equipped frame, and are looking to save some coin by repurposing the parts off of last year's rig and are running into the age-old issue of incompatible brake caliper mount styles. Instead of ponying up for shiny new flat-mount calipers, get some use out of those post-mount ones with TRP's Flat Mount Disc Brake Adapter. With options for running 160mm or 140mm rotors, and added options for flat-mount to flat-mount pairings, these adapters will have you up and running and out exploring new roads in no time at all.
