Flat Mount Disc Brake Adapter

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.

  • Disc brake caliper mounting adapters
  • Adapts post-mount calipers to flat-mount frames
  • Also available in flat-caliper to flat-mount frame options

Great Adapter

I returned this product before using it
True to size

I bought this hoping it was compatible with the 22mm disc mount spacing on a Gary Fisher I am updating. Unfortunately it does not fit, however it is well machined and comes with the necessary hardware to mount to the frame. If this works for you bike, it will be a great investment.

Only adapters I use

I've put it through the wringer

There's something about these that has me married to them. Maybe because it's easy to figure out which one I need? The name? Minimal branding? I dunno but I like 'em and they work fine.


Will these work for front post mount fork, to flat mount calipers and 160 rotors?
