The Ultegra Di2 FD-R8050 front derailleur by Shimano - things do get this fast

With the Shimano Ultegra Di2 FD-R8050 front derailleur, you can effortlessly perform high-precision gear changes at breath-taking speeds. The 2x front derailleur is equally suitable for both rim and disc brake frames and still works smoothly even under high loads. With a capacity of 16 teeth larger differences between the chainrings are no problem. Firmware updates can be performed via the E-Tube platform. The FD-R8050 also features the revolutionary Synchro Shift and Semi Synchro Shift functions, which guarantee optimum tuning to the 11-speed rear derailleur.

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.

Synchro Shift / Semi Synchro Shift
If the full Synchronized Shift mode is activated, you can control the front derailleur and rear derailleur with a single shifter. The front derailleur recognizes the position of the rear derailleur and automatically shifts to the most efficient ratio with the optimum chainline, so you don't have to shift in the front or make corrections. The Semi Synchronized Shift mode is a function that automatically shifts the rear derailleur when the front derailleur is shifted and ensures optimum shift transitions. This gives you more control and allows you to adapt the range combination to your personal riding style. Shimano Synchronized Shift is fully compatible with E-Tube and therefore customisable.
