Control at the Tip of your Finger
The components of Shimano's Ultegra series have always stood for innovative technology, dependability and high performance. That explains why the term 'ULTEGRA' has become part of the vocabulary across the bicycle world. Road bikes equipped with Ultegra serve a wide range of user profiles - from mileage-hungry touring enthusiasts to recreational cyclists with racing ambitions to semi-professional club riders.
Now also with Electronic Shifting: The introduction of electronic Ultegra Di2 shifting components now puts the finishing touches to Ultegra. It gives users the freedom to choose between mechanical and electronic shifting, whichever they prefer. Once again, Shimano's top group Dura-Ace has inspired the advanced component technology of Ultegra, making it available to road enthusiasts as of now.
Not compatible with Dura-Ace Di2 components.
About Rear Derailleurs
Various derailleur systems were designed and built as far back as the late 1800s. A French bicycle tourist, writer and cycling promoter Paul De Vivie (1853-1930), invented a two speed rear derailleur in 1905 which he used on forays into the Alps, and we wonder if 20 gears are enough..... Since then there have been many advancements, in the number of gears, materials and reductions in weight. Wiggle lists a large selection of front and rear derailleurs catering for double and triple systems with 7, 8, 9, 10 and even 11 speed cassettes.
