Shimano GRX Hydraulic Disc Brake Caliper BR-RX820

SHIMANO GRX, with its gravel-specific ergonomics, optimized gearing options, rugged reliability, and quiet and stable drivetrain, sets itself apart from the rest of the component world. It isn’t a reworked set of road components. It represents a ground-up look at how cyclists want to explore their world. SHIMANO GRX helps you eliminate excuses, instead urging you to try that rough sidetrack or ride that little bit longer. It offers you the option to Explore Beyond.
