Caliper size: 100mm VS. 108mm

Brake caliper sizes 100mm vs. 108mm refer to the distance between the mounting bolts, with Japanese bikes typically using 108mm and European bikes using 100mm.

Caliper offset

The offset refers to the lateral distance between the brake disc and mounting points.
It's a crucial measurement that determines how the rotor aligns with the brake caliper and pads. Proper offset ensures the rotor sits in the ideal position
100mm radial caliper has 30mm offset
108mm radial caliper has 22.5mm offset
