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.
