Shimano Dura-Ace Di2 ST-R9150 Shift/Brake Levers - Further customisation thanks to E-Tube

The Shimano Dura-Ace Di2 ST-R9150 shift/brake lever set allows you to shift electronically (2x11-speed) and operate a mechanical rim brake thanks to STI Dual Control technology. It is characterised by clear feedback for even more intuitive gear changes, optimum brake modulation with the SLR-EV system and sophisticated ergonomics. The Multi-Shift options, which can be set via the E-Tube platform, the programmable shifting stages and a remote control switch ensure maximum individualisation. The ST-R9150 is made almost entirely of lightweight carbon.

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.
