The Shimano GRX ST-RX825 Di2 Shift/Brake Lever BR-RX820 Brake Caliper is the ultimate upgrade for gravel riders seeking the highest level of control, comfort, and customization. Built for 12-speed Di2 wireless shifting, this system delivers lightning-fast, reliable performance across mixed terrain, letting you focus on the ride ahead. Designed with gravel-specific ergonomics, the raised hoods, ribbed texture, and anti-slip coating provide enhanced grip and confidenceespecially when the trail gets rough.

Optimized for use with flared handlebars, the RX825 levers retain Shimanos third-button location and support FRONT SHIFT NEXT programming, allowing a single button to control both upshifts and downshifts on the front derailleur. This clever feature frees up other buttons for custom functions, and compatibility with satellite shifters (sold separately) makes your setup even more dialed. The BR-RX820 caliper uses a 2-piston design for refined modulation, a quick bite point, and 10% wider pad clearance for reduced brake noise. Its also easy to maintain thanks to Shimanos one-way bleeding system.
