The Dura Ace Di2 shift/brake levers ST-9070 by Shimano - a new precision benchmark


The Shimano Dura Ace Di2 ST-9070 shift/brake levers - from the second generation of electronic Shimano Road drivetrains and therefore 2x11-speed compatible - inspire with high-precision gear changes that can be controlled without any effort. Its smaller lever diameter makes it also suitable for riders with smaller hands. Two connections for Sprinter shifters extend the possibilities. On the brake function side, SLR-EV technology ensures optimum modulation. Of course, the ST-9070 Di2 Dual Control levers can always be kept up to date with the E-Tube platform.

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 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.

SEIS
A technological innovation of the computerized shifting system based on the DI2 concept with which is called, the SEIS (Shimano Electronic Intelligent System). The SEIS innovative shift technology is still based on the Shimano Index System (SIS) that has proved its superior gear changing characteristics over the years. The big difference is that in this case, the shifting action is provided for by electronics instead of mechanics. Shifting is executed by simply pressing the button. No power is needed to shift, which gives important advantages since it is easier now to always keep a tight grip on the handlebar and to keep your concentration on riding instead on shifting. The shift system allows accurate and effortless shifting in difficult circumstances for example when you have cold hands or when you are completely exhausted. Furthermore, the shifting performance will never be affected by contaminated or stretched cables since the shifting signal is transferred electronically. The operating buttons work similarly to mechanical Dual Control Lever so you don't need to re-program your mind for the SEIS.

E-Tube
The E-Tube platform's " Plug & play" and wireless connections make it easier than ever to check and adjust DI2 components on your PC, tablet, or smartphone. The E-Tube project's cutting edge features are protected with an advanced all-weather design that resists rusting, stretching, and freezing. It provides optimal flexibility for your bike. The E-Tube project lets you customise settings of compatible electrical components, update to the latest firmware for feature improvements on Windows PC, tablet or smartphone, quickly access important components' data, and instantly check the system's status.
