Promax Post Mount Disc Brake Adapter for Post Mount Frame/Fork, Fits 180mm and 160mm Rotors Info

The Promax Post Mount Disc Brake Adapter for Post Mount Frame/Fork lets you run a larger or smaller rotor than your frame or fork was originally specced for — without sourcing a new caliper or swapping mounts. It converts between 180mm and 160mm rotor sizes on post mount interfaces, making it a practical solution when upgrading rotors or building up a wheel with a different rotor diameter than your current setup.

Straightforward to install and designed to maintain proper caliper alignment, this adapter keeps your braking geometry correct across rotor sizes. A reliable piece of hardware for anyone fine-tuning a disc brake drivetrain.

  • Compatible with: Post mount frame and fork
  • Rotor sizes supported: 180mm and 160mm
  • SKU: PM180F
