Shimano GRX, with its gravel specific ergonomics, optimised gearing options, rugged reliability, and quiet and stable drivetrain, sets itself apart from the rest of the component world.
The GRX RS717-L 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.
Technology
Dual Control Lever
DCL stands for Dual Control Lever. It has brake and shifting functions in the system and enables easy operation.
Ergonomic innovation is probably more critical to the higher standard performance than the added gearing. The shift internals borrow the robustness from Shimano's MTB technology and are so smooth and effortless that one finger shifts front and rear are possible. Indeed, shifting is the ultimate act of Shimano Total Integration, and simply has to be experienced to be understood.
