Shift/Brake Lever Shimano GRX ST-RX600 Left, 2-Speed

The Shimano GRX ST-RX600 left 2-speed Dual Control (STI) lever is designed for gravel riding, delivering confident control and reliable braking performance in demanding conditions. Intended for 2x11 drivetrains, this lever controls the front derailleur and ensures smooth, precise shifting.
