SRAM Disc Adapter

This adapter is designed to mount a disc brake caliper to an International Standard (IS) frame or fork mount without adding any additional offset. It ensures your brake caliper sits at the exact position required for standard rotor alignment.

You need this adapter if your frame or fork features IS tabs, which are characterized by two holes spaced 51mm apart that run parallel to the wheel axle. If your frame uses Post Mount tabs instead, this adapter will not be compatible.

Because this is a 0mm offset adapter, it is intended for specific setups where the caliper mounting position matches the rotor diameter natively. You should verify your frame or fork's native rotor size compatibility before installation to ensure the brake pads align correctly with the rotor track.

While engineered by SRAM for optimal performance with their braking systems, the IS standard is universal. This adapter will generally work with other brands of calipers, provided they are designed for the same IS mounting interface.

The adapter typically includes the mounting bracket itself. You will need to reuse your existing caliper mounting bolts or source appropriate hardware that matches your specific caliper and frame interface.
