Technologies

DCL (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.

The 105 Dual Control Lever has an optimized structure with features that include the lighter weight pivot section in the near side of the shifting unit and the integral shifting cable for lighter steering. Its many component parts are made so compact and precise to achieve unprecedented high-speed performance.

SIS Rear Index Shifting System

The system constituents such as the index mechanism built in the shifting lever, the frictionless SIS rear index shifting cable and the smooth action rear derailleur realize the SHIMANO INDEX SYSTEM. S.I.S. offers smooth and precise shifting.

Reach Adjust

Brake lever is equipped with a reach adjust mechanism. The distance from handlebar grip to lever can be adjusted to suit any hand size, type of riding and individual rider preferences.
