Shimano Ultegra R8050 Di2 11 Speed Groupset
Shimano Ultegra R8050 Di2 11sp Groupset
The Shimano Ultegra R8050 Di2 Groupset provides market-leading electronic gear shifting thanks to the Di2 system and trickle-down technology from professional-level Dura-Ace groupsets.
This system ensures shifting accuracy, which provides crisp and precise shifts with every push of a button. No adjustment is required once setup, instead of mechanical cables you have fully sealed, high-end Di2 electronic wires that relay your gear selection instantly; this truly is the essence of modern, electronic drivetrain efficiency. Maintenance-Free Electronic Gear Shifting Precision The power and precision of Di2 is unmatched.
It enables beautifully smooth shifting both front and rear.
The lack of maintenance and adjustment is impressive: once you've customised your Di2 to shift to your preferences, it will continue to do so endlessly. Synchro Shift for Outstanding Cycling Performance Synchro Shift creates an intuitive experience with synchronised front and rear shifting, which can be custom programmed.
With 'full' and 'semi' Synchro Shift available, this intuitive new mode automatically reacts when you shift from one chainring to another. Remove the guess work as your rear derailleur shifts automatically to minimise the gear step so you can keep riding with a smooth cadence and rhythm. Low Profile, Reliable and Efficient Di2 E-Tube System The Di2 E-Tube system provides unmatched shift performance, reliability and rider customisation.
Along with enhanced Di2 functionality, the front and rear Di2 derailleurs are connected via Shimano's small EW-WU111 wireless unit allowing for an ANT Private connection between the groupset and third party devices. These components can be connected to Shimano´s E-Tube software, which supports the programmable aspects of the Di2 electronic gear shifting system. Use the Bluetooth technology for seamless access on smartphones and tablets.

Shimano are a Japanese manufacturer primarily known for their cycling components, and to a lesser extent shoes and clothing. Founded in 1921, Shimano is widely believed to be the largest cycling component manufacturer in the world, having reached this status through a combination of innovation, reliability and value for money. Whatever your style of riding, whether it be road or MTB, Shimano will have a component range to suit your level and budget, from the low end Alivio and Tiagra to the professional standard XTR and Dura-Ace. Over the years, Shimano have revolutionised bicycle gear, brake and pedal systems, such as the recessed SPD, Hollowtech crank arms and smooth shifting Hyperglide sprockets. Initially their component range faced competition from Suntour, whereas nowadays their primary rivals for market share are SRAM and Campagnolo. If you wish to save money on their components and apparel, please visit my Shimano section, where I list as many money saving deals as I can find.
