Shimano's refinements to the latest Ultegra Di2 group are truly remarkable, and while we always fancy a full Dura-Ace build, we'd be hard pressed to decipher a difference in performance. That makes sense since Ultegra gets Dura Ace trickle down technology, and for rear derailleurs, the RD-R8050 borrows heavily from the firm's top-end Dura-Ace RD-R9150—including the low profile Shadow design. This profile places it closer inbound to the frame and tucks the derailleur under the cassette. This protects the derailleur in the event of a crash and in general from getting banged around, so it remains better aligned making shifts smooth, quick, and accurate. The RD-8050's new geometry allows for shorter throws that result in faster and more precise shifts even over a wider range 11-34 cassette. Updated with a SHIMANO SHADOW RD design, the SHIMANO ULTEGRA 8000 rear derailleur offers a sleek appearance and optimized shifting performance. The RD-8050 Di2 versions offer the digital precision of SHIMANO electronic shifting and synchronized shifting. The Shimano Ultegra Di2 R8050 Rear Derailleur will help you maintain race concentration through intuitive shift control. The new low-profile design of Shimano Shadow RD increases its shift stability and gives the rear derailleur a sleek and integrated appearance. Race endurance is guaranteed, through the optimized slant angle. The wide compatibility of two specific rear derailleurs (GS and SS) for cassettes 11-25T to 11-30T and 11-28T to 11-34T will secure a smooth ride in even the highest and steepest mountain areas.
