The GRX RS717 brake lever (for Di2) is a left-only brake lever option that pairs perfectly with a right ST-RX715 DUAL CONTROL LEVER thanks to its matching shape and ergonomics. Skipping all the shifting electronics, it's a lighter, simpler left brake lever option for times when less is more.

The GRX BR-RX410 disc brake caliper brings a new level of control to gravel cycling with enhanced modulation and a quicker initial braking point. And despite its smaller construction, the system is quieter and easier to maintain.
