The SHIMANO RX820-LA DUAL CONTROL lever integrates brake lever and dropper post lever into a seamless unit, allowing for quick and effortless operation and a tidier, clearer cockpit. The GRX BR-R820 disc brake caliper offers gravel riders an entirely new sense of control thanks to improved modulatability and a quicker pressure point. And despite its flatter design, the system is quieter and more maintenance-friendly than ever before.
