The Shimano Ultegra Di2 ST-R8050 Shift/Brake Levers are characterised by their ease of use

The Shimano Ultegra Di2 ST-R8050 Shift/Brake Lever set includes left and right Dual Control shift levers, which can also be used for racing bike rim brakes. Tactile feedback operates similarly to electronic shifting mechanisms. You notice a clear difference between the shift buttons, even while wearing thick gloves. The E-Tube platform offers numerous customisation options, such as 2- or 11-speed programmable shift levels, Multi-Shift, or remote control switch configuration. The Ultegra Di2 STI boasts other attractive features, including generous reach adjustment and safe braking power levels in the SLR-EV System.

STI Dual Control (DCL)
DCL stands for Dual Control Lever. It has braking and shift functions and allows easy operation. The improved ergonomics is probably even more important for the high standard than more range. The shift levers bring the stability of Shimano MTB technology and work so precisely and smoothly that it is possible to shift gears both front and rear with just one finger. This is a highlight of Shimano's " Total Integration" (STI). You have to experience it for yourself to believe it.

This product uses a technologically innovative, computerised shifting system based on the Di2 concept with the product designation SEIS (Shimano Electronic Intelligent System). The innovative shifting technology of the SEIS continues to be based on the Shimano Index System (SIS), whose outstanding shifting performance has proven itself over many years. The main difference between the systems is that the shifting operation is no longer carried out mechanically but electronically. The shifting process is carried out by simply pressing a button. No effort is required to shift gears, which has significant advantages as the rider always has a firm grip on the handlebars and can concentrate on riding without being distracted by the shifting. The shifting system allows precise and effortless shifting in all situations, even with cold hands or when the rider has fully exerted themselves. In addition, the shifting capacity can no longer be affected by dirty or stretched cables, as the shifting signal is transmitted electronically. The operating keys work in a similar way to mechanical dual-control levers, making it easy to get used to the new system.

E-Tube is a system platform for the Di2 concept (Digital Integrated Intelligence). E-Tube transmits interactive signals and supplies all electronic parts with power via " Plug & Play" connections. E-Tube is resistant to corrosion, expansion and frost and ensures low maintenance. It offers optimal flexibility for your bike. With E-Tube Project you can customise the settings of electronic components and update the firmware via Windows PC, tablet or smartphone. It provides quick and easy access to information on electronic components and provides an instant overview of system status.
