The REVERSE Bremsscheibenadapter IS-PM 203 Shimano HR is a robust disc brake adapter designed to let you run a 203 mm rotor on frames or brake mounts with IS (International Standard) interfaces using a Post Mount brake caliper. Optimized for Shimano-compatible rear brake setups, this adapter ensures precise alignment between caliper and rotor, giving you powerful, consistent braking performance on demanding terrain. Whether you are upgrading from a smaller rotor for more stopping power or replacing a worn adapter, this component offers a clean, secure fit and reliable function.
Manufactured from durable metal and engineered for high loads, the REVERSE IS-PM 203 adapter is ideal for aggressive trail, enduro, or downhill riding where strong braking is essential. The design helps maintain correct rotor spacing and caliper position, reducing the risk of rubbing and uneven pad wear when installed correctly. It is a practical upgrade for riders who want more braking leverage on long descents or with heavier bikes. Pair it with a quality 203 mm rotor and compatible Shimano rear brake for a noticeable boost in control and confidence.
