Technologies

E-Tube

• E-TUBE is Shimano's ''service'' that uses websites or apps to maximize the enjoyment of riding a bicycle by connecting the riders, the bicycles and SHIMANO.

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.

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 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.
