The Shimano Dura-Ace Di2 ST-9070 shift/brake levers - from the second generation of Shimano electronic road shifters 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 allow for further possibilities. On the brake side, SLR-EV technology ensures optimum modulation. Of course, the ST-9070 STI Di2 Dual Control levers can always be kept up-to-date using the E-Tube platform.

By refining the technology, it became possible to make shifting so smooth at the front and rear that they can be triggered with just one finger. Shimano calls such levers Dual Control Levers (DCL).Digital Integrated Intelligence (Di2)Di2 systems are the electronic shifting systems from Shimano. They are based on the SEIS, the Shimano Electronic Intelligent System, which takes over the index shifting function from the mechanical components, only via power cables or radio signals and not via a Bowden cable. Shifting is done by simply pressing a button. This has the advantage that no great effort is required, your concentration on the ride is not disturbed and operation is easy even with cold hands. In addition, the electronic gear changes are very fast and highly precise. There is also no risk of a defective circuit due to dirty cables or other problems. You can adjust individual settings via the E-Tube Project, such as adjusting the shifting speed, the number of shifting operations per button press or the Synchro or Semi-Synchro shifting function. Shimano offers an app for this purpose. Gear maintenance and firmware updates are also done via E-Tube, with the bike connected to a PC running the appropriate E-Tube software for more extensive workshop work.
