The Ultegra Di2 ST-6870 Shift/Brake Lever by Shimano - Intuitive operation

The Shimano Ultegra Di2 ST-6870 shift/brake lever - available in 2-speed or 11-speed - electronically delivers high-precision shifting performance that is easier to access than ever before. Thanks to the intuitive arrangement of the switches, operation will not be difficult at all, even for those who have preferred mechanical switching up to now. It even expands the possibilities, for example with the two connections for Sprinter switches. Of course, the ST-6870 Di2 STI Dual Control levers can always be kept up-to-date with the E-Tube platform. On the brake side, SLR-EV technology ensures optimum modulation.

STI Dual Control
Shimano Total Integration (STI) means the combination of braking and shifting functions in one lever, which increases safety when riding. 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.
