The Shimano Ultegra R8060 Di2 groupset offers the fastest shifting performance, the best brake properties, and the most durability you could ever want. The Ultegra R8060 has also been optimised for wider rims and tyres. 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. 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. |
