The ST-R8150 electronic shift/brake lever from Shimano's Ultegra Di2 road bike groupset shifts 12-speed or 2-speed by cable and brakes mechanically. It scores with fast gear changes that are defined and intuitive thanks to the Shimano index shifting system. Cables are routed from the STI first to a junction box and then to the battery, which in turn is connected to the rear derailleur and front derailleur. You can also connect the STIs to each other and run a cable from the right shifter to the battery. The ergonomics of the dual-control lever and the horns have been further optimized compared to previous models, and allow a very comfortable grip. You can easily adjust the grip width with a flat head screwdriver. The brake lever is made of lightweight aluminum, and the grip body is made of plastic, which saves additional weight.

Technology:

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.
