Shimano Brake Disc Adaptor Front Ø180mm PM Brake -> PM Frame

This Shimano front disc brake adapter is designed to allow you to use a Ø180 mm rotor on a Post Mount brake system, converting a PM brake caliper fitment to a PM frame or fork mount for correct alignment and safe braking performance. It positions the caliper at the proper distance from the axle so the pads track the rotor accurately, making it a reliable solution for rotor size upgrades, replacements, or workshop builds where precise spacing is essential for smooth, quiet braking.
