The correct adapter must be selected based on your bicycle's fork type (A-Pillar or B-Pillar) and the desired disc rotor size. Refer to the diagrams and charts below for compatibility and visual guidance.

5.1 Understanding Fork Types and Rotor Sizes

Bicycle forks typically come in two main mounting standards for disc brakes: A-Pillar (Post Mount) and B-Pillar (International Standard or IS Mount). Adapters convert between these standards and allow for different rotor sizes.

Figure 1: A-Pillar and B-Pillar Fork Configurations with Rotor Sizes

A-Pillar Fork:

  • Front wheel 160 rotor
  • Front wheel 180 rotor

B-Pillar Fork:

  • Front 160 rotor / Rear 140 rotor
  • Front 180 rotor / Rear 160 rotor
  • Front 203 rotor / Rear 180 rotor

5.2 Adapter Instruction Chart

Use the following chart to determine the correct adapter for your brake caliper series, fork type (Front/Rear), and desired rotor size. F indicates Front, R indicates Rear, PM indicates Post Mount fork.
