TRP CNC Post Mount Disc Brake Adaptor

TRP's post-mount adaptors — a CNC-machined bracket that moves a post-mount caliper out to the rotor size you want to run. Mounting bolts and washers included.

Highlights

  • CNC-machined
  • P17: 203 to 220 mm
  • P20: +20 mm (160 to 180, 200 to 220, 203 to 223)
  • P23: 180 to 203 mm
  • P40: 180 to 220 mm
  • P43: 160 to 203 or 180 to 223 mm

Pick the adaptor by your fork or frame's native post-mount size and the rotor you want to fit.

Fit and compatibility

Check your bike maker's maximum and minimum rotor size before going up a size — TRP's note, and ours. Post mount only; flat-mount frames need the flat-mount adaptors.

Choose your size from the options above. Not sure what fits? Ask us — we fit and service these in our workshop.

TRP covers this product against defects in materials and workmanship for two years from purchase. Wear items, crash damage, and damage from incorrect fitting, adjustment or maintenance are not covered. If you have a warranty concern, return the item to Tune Cycles and we will manage the claim with the distributor on your behalf — you do not need to contact TRP or the importer. This sits alongside your rights under the Australian Consumer Law.
