How to choose your MTB disc brake adapter

The adapter connects the caliper to the frame or fork mount. It allows you to fit a larger rotor without changing the brake. Shimano, SRAM, Magura, Hope and Galfer cover all common setups.

Which mounting standard?

  • Post Mount (PM) : two bolts parallel to the wheel, the dominant MTB standard.
  • International Standard (IS) : two perpendicular bolts, found on older frames and forks.
  • An adapter IS to PM exists and remains common; the reverse is much rarer.
  • Check the standard on your fork and chainstays: it may differ between front and rear.

Which adapter for which diameter?

  • The adapter is selected according to the difference between the original diameter and the target diameter, not by diameter alone.
  • Moving from 160 to 180 mm requires a +20 mm adapter; from 180 to 203 mm, a +23 mm adapter.
  • A caliper fitted without an adapter corresponds to the smallest diameter accepted by the mount.
  • Check the maximum diameter accepted by your fork and frame before fitting a larger rotor.

Front or rear?

Front and rear adapters are not interchangeable: bolt spacing and orientation differ. Order the reference corresponding to the position, and ensure you have bolts of the correct length — the original ones can rarely be reused after changing rotor diameter.

After fitting

A poorly aligned adapter causes constant rubbing. Loosen the caliper slightly, fully apply the brake, then alternately retighten the bolts to allow the caliper to centre itself on the rotor.
