Shimano GRX RX820 12 Spd Shift/Disc Brake Kit - Rear Gravel is the great equalizer. No matter who you are, where you come from, or where you want to go. Gravel celebrates individuality. It welds together in a shared passion. It lays the foundation for friendships and creates memories for the ages. Whether you ride one kilometer or a hundred. Whether with professional equipment or without. With a 10-speed, 11-speed or 12-speed gear system. Whether on paved roads, forest roads, back roads or no roads at all. It does not matter why you are out there, all that matters is that you are. Shimano GRX shift/brake set consisting of the ST-RX820 Dual Control lever for confident handling and the BR-RX820 hydraulic disc brake caliper for consistent braking performance. For a smooth and at same time easy maintenance provide a proven Bleeding system, which greatly facilitates brake line replacement. Shimano GRX ST-RX820 brake/shift lever The Shimano GRX provides Gravel inspired ergonomics both for the bracket design to accommodate every kind of drop bar and for the lever itself featuring an anti-slip coating for greater mixed-terrain control. In order to meet the individual needs of the driver, the hydraulic brake lever offers a tool-based reach adjustment as well. Shimano GRX BR-RX820 disc brake caliper Never hesitate to tackle rough surfaces with the hydraulic Shimano GRX caliper. In doing so Ice Tech ensures excellent heat dissipation under all conditions. The Flat Mount system makes it possible to attach the disc brake caliper directly to frame or fork. Trouble-free and simple maintenance is provided by the proven Way Bleeding concept and the Easy Hose Joint System which simplifies brake hose exchanges. Dual Control Lever (DCL) / The Shimano DCL levers combine braking and shifting functions in one control unit for easy as well as comfortable operation. In raising the standard of performance, their innovative ergonomics are even more important to consider than adding additional gearing. However, the highlight of the STI shifters ( Shimano Total Integration ) shifters, is the ability to change gears front and rear with just one finger. The levers owe this not only to an extremely precise and smooth operation but also to the same stability for which Shimano's MTB technologies are already known. J-Kit (Easy Hose Joint System) / For brake systems with brake hose connections, the brake lever has an integrated squeeze seal (olive), which makes the installation and removal of the brake line much easier overall. Ice Technologies / In order to keep the braking power at longer continuous operation consistently high, Shimano has developed cooling technology for brake discs and brake pads. Brake pads feature cooling fins made of aluminum, which better dissipates heat. In conjunction with the optimized radiation properties of the rotor, this results in a longer durability of the pads, while brake noise and fading are minimized.
