Fullstop Disc Brake Adaptor PM-IS: F160/R140

From Fullstop, the Disc Brake Adaptor PM-IS is a practical solution for fitting a post mount calliper to a frame or fork with an IS-style mount. It’s designed to help you achieve the correct set-up when pairing your braking system with specific rotor sizes, making it a useful choice for compatible bike builds and maintenance.

Engineered for a 160mm rotor on the front or a 140mm rotor on the rear, this adaptor supports accurate alignment between calliper and rotor where the mounting standards differ. Ideal for riders and mechanics working with mixed mount types, it offers a straightforward way to match components without changing the frame or fork mount.
