The Shimano SM-MA-F203P/PL2 is a post mount disc brake adaptor that lets a 200mm Post Mount fork or frame accept a larger 203mm rotor. This simple bracket bridges the gap between your frame's mounting tabs and a bigger brake disc, giving you more braking surface without swapping the fork or frame.
Built from durable metal to Shimano's standard tolerances, this adaptor fits a 74mm Post Mount interface and comes with the hardware needed for installation. It is a straightforward way to upgrade stopping power on bikes already set up for 200mm rotors, matching nicely with compatible Shimano calipers and rotors.
