The new Ultegra R8000 series is taking our rider-tuned philosophy to the next level, with an extensive range of components for mechanical shifting, electronic shifting (Di2) and time trial / triathlon.
The Di2 (RD-8050) or mechanical (RD-R8000) rear derailleur (RD) adopts the Dura-Ace low-profile Shimano Shadow RD design to sit fully under the cassette, tucked away from potential damage. The RD comes in a short cage (SS) design to cover 11-25T to 11-30T and a longer cage (GS) design to cover 11-28T to 11-34T. Both front and rear Di2 derailleurs communicate with each other to operate full or semi Synchronized Shifting mode, allowing the rider to maintain concentration on the road or the race ahead.
