Technology
Dual Control Levers
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 our 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 Intergration, and simply has to be experienced to be understood.
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.
Shimano’s genuine application E-Tube Project Cyclist allows you to customize your bike, update firmware, and maintain it by connecting it wirelessly to your bike. You can also get the more detailed bike maintenance by connecting to your bike by wire with E-Tube Project Professional application.
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.
Features
- Wireless connectivity to the front and rear derailleurs for effortless trouble free gear shifts
- With Di2 technology shifting is easy and precise - just a light touch, as soft as a mouse click, is sufficient for the front or rear derailleur to instantaneously select the correct gear
- Full and semi synchronized shifting programable, Synchro shift compatible meaning a single shifter can control both front and rear shifting which can be fully custom tuned to your riding preferences. Semi synchronized shifting means when a front shift is made the rear mech will automatically correct to the appropriate ratio
- Simply pressing tactile buttons allows effortless and comfortable shifting even when your hands are cold
- Drop bar STI with shift buttons located in a near identical place to the positions you'd assume shifting using a mechanical Shimano STI
- Hydraulic brake lever provides excellent stopping power
- Hydraulic reservoir tank provides pad to rotor clearance auto-adjust maintaining braking performance during pad wear
- Finely tuneable reach adjusters for the levers enable custom fitment for all hands
- Levers use CR1632 batteries which last for approximately 1.5-2 years
