Galfer FD465 Hope E4/RX4 Shimano Brake Pads The Right Compound for Every Condition Hope's E4 and Shimano's RX4 calipers are serious hardware, and these pads give you compound options to match how you actually ride. Whether you want the smooth, progressive feel of the standard compound for everyday trail and road use, or the high-output stopping power of the Pro compound for race days and demanding terrain, the FD465 line has a formulation for the job. Galfer engineers each compound specifically for bicycle braking variables, including rider weight, terrain, humidity, and temperature, so performance stays consistent across conditions. The organic semi-metallic construction keeps rotor wear low and noise minimal, no matter which compound you run.
