DCL (Dual Control Lever)

The lever performs braking and shifting functions and is easy and intuitive to use. Ergonomic innovation is key to the highest performance standards. The new internal shifting mechanisms owe their robustness to Shimano MTB technologies and are so efficient that you can change gear or chainring with just a fingertip. In fact, the shifting action represents the ultimate realization of the Shimano Total Integration philosophy, and only those who have tried it can understand its benefits.

The 105 Dual Control Levers have an optimized structure with features such as a lightweight pin section on the inner side of the shifting unit and an integrated shift cable to lighten steering. The numerous components have been made compact and precise to ensure unprecedented performance at high speeds.
