The Shimano Ultegra R8050 Di2 groupset offers the fastest shifting performance, the best brake properties, and the most durability you could ever want. The Ultegra R8050 has also been optimised for wider rims and tires. Ergonomically shaped Di2 shifters, new covers for the Di2 buttons, and with improved adjustability when it comes to shifting options. Synchronized Shifting is available to set-up the shifting speed and options to your liking. Finally, the rear derailleur uses the Shadow Technology for a lowered, more protected profile which helps aerodynamics and reduces the chance of damage.

In 2008 SHIMANO first introduced electronic shifting to road cycling in its Dura-Ace 7970 groupset. In 2011 it became available for Ultegra. Today SHIMANO announced they will integrate its electronic shifting technology (Di2) in their recently introduced Ultegra 6800 groupset. Ultegra takes pro-tested technologies to a wider audience. Whether it is a mechanical or electronic shifting interface, Ultegra provides the highest quality outside professional racing.

The DNA for both the mechanical and electronic version of the group is the same. They share the same 4-arm cranks, 11-speed cassettes, dual pivot brakes, Sil-tec chain and 11-speed wheels. What makes them different is the shifting interface (shift lever and derailleurs). Where Ultegra 6800 uses the well known mechanical parts and cables, Ultegra 8050 (Di2) uses an electronic shifting system.

Compared to the previous Ultegra Di2 (6870) SHIMANO improved the ergonomics of the dual control lever for easier access. Especially on top of the slimmer hoods riders have more control than ever. Also the shape of the shift button improved and the contrast of the surface is more recognizable.

The derailleurs are more compact and lighter than their predecessors. The rear derailleur is updated with an automatic protection system that moves the cage out of harms way in case of a crash. There are two versions of the rear derailleur. A SS for cassettes up to 28T and a GS for cassettes up to 32t. The 32t GS rear derailleur in combination with a compact front crank setup offer a full wide gearing setup. Both rear derailleurs are featured with multi shifting. With a single press and hold of the shift button the rear derailleur goes all the way up or down the cassette. Or, when programmed at the E-tube platform, two or three gear shifts. Also the speed of gear shifts can be adjusted. In five steps, from very slow to very fast.

    Not being a Di2 expert, Texas Cyclesport was excellent in their communication to ensure I was fitted with the proper selections. They reached out with couple of phone calls and emails to ensure I was set up appropriately. Conversion was perfect and a great upgrade. Will continue to work with them in the future. Thanks for great service !

    Di2 Upgrade Kit

    The configuration worked well to come up with a complete and accurate kit. The people at Texas Cyclesport were really helpful with a couple of questions I had relative to wire length. The kit was received on time and complete and really works beautifully. An investment well worth the money.

    Fantastic group set and great price. Set aside ample time to do a great job considering that the cranks and bottom bracket will need to be removed to install the Junction B box in the base of your down tube. You will need a clamp if you do not have a braze on mount. Choose your e-tube cable lengths carefully since you can’t extend them but you can always hide them inside your frame. Shifting is silky smooth and quick. Set up of front and rear mech takes minutes and you never have to worry about trimming the front mech anymore. You can cycle through manual, semi-synchro, and full-synchro modes by double tapping the button on the Junction A box.

    As good a system as they make it out to be. Shifts great, terrific ergonomics on the shifters, easy to install. Texas provided great service with frequent e-mail updates as to order status for a backordered item, as well as the best price found.
