Technology:

STI Dual Control (DCL)
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 high standard performance than the added gearing. The shift internals borrow the robustness from the MTB technology and are so smooth, that effortless 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.

Optislick
Optislick cables feature a minimal and uniform electrically coated layer that improves routing efficiency and provides excellent corrosion resistance.
