Brake calipers

Gravel cycling has its roots in simplicity, inclusivity, and curiosity. Everyone, from beginners to seasoned veterans, relies on Shimano GRX, the first gravel-specific groupset - for smooth shifting, reliable braking, and exceptional off-road comfort. Shimano GRX stands apart from the rest of Shimano's component lineup, and the new RX820 series offers premium performance at an incredible price, with thoughtful ergonomic design and gearing focused on gravel roads. This is not a re-engineered road component set. It represents a fundamental approach to how cyclists want to explore their world. Shimano GRX helps you eliminate excuses, instead encouraging you to try the rough side road or endure in the saddle for much longer. The standalone front hydraulic brake caliper from the new 12-speed GRX gravel series is designated BR-RX820. It features traditional Flat Mount mounting to the fork using the included adapter, with which a 140 mm or 160 mm rotor can be used. Included with the caliper are L05RF Resin pads with cooling fins. The caliper weighs 134 g.
