Post to post brake mount to mount your caliper for a rotor size, dependent on what rotor you have, and what your fork/frame has as standard.

Ultimate adaptors are XTR level and use a lighter alloy with more cutouts to save a couple of grams in weight.

F 160-180mm - R 140-160mm 160-180mm: 

  • +20mm increase
  • Allows for 180mm rotors on 160mm post mounts.  

F 180-203mm - R 180-203mm:

  • +23mm increase 
  • Allows for a 203mm rotor on 180mm post mounts.

F 160-203mm - R 160-203mm: 

  • +43mm increase 
  • Allows for a 203mm rotor on 160mm post mounts.
  • Fits via 4 bolts with the caliper offset

If there is an adaptor, but it bolts to the frame from the side, then it's an IS mount, and you'll need a different adaptor.

Nicelly made although careful not to overtighten the bolts as they are quite a soft alloy and strip easily. Also works for adapting 140mm rear post mount to 160mm (what I'm using it for).
