Shimano RD-R8050 Ultegra Rear Derailleur Di2

Precise wireless Di2 shifting for E-MTB and LINKGLIDE compatibility. The ultra-robust XT RD-M8260 11-speed rear derailleur with long cage offers features that everyone will appreciate. The rear derailleur uses the same wireless Di2 shifting technology and other strengths of the XT, but is powered by the e-bike's main battery, ensuring a stable power supply. Robust, intuitive and consistent: XT Di2 RD-M8260 Linkglide 11-speed E-MTB Rear Derailleur from Shimano What doesn't get hit can't get broken - the flat, wedge-shaped design of the new XT rear derailleur prevents most stone chips and impacts on the trail. And if an impact does occur, the rear derailleur can slide off obstacles on the trail thanks to the smooth outer coating, preventing catastrophic damage. The automatic impact recovery function immediately returns the derailleur motor to its original position after an impact, while the wide joint structure, durable plate, skid plate design and solid derailleur pulleys ensure robustness and durability. From the foundational moments in the early 1980s when DEORE XT first revolutionized mountain biking, SHIMANO brings fast and reliable shifting, a robust drivetrain construction, and refined braking systems to more riders with the latest introduction of DEORE XT M8200 Di2 components. Following the recent launch of our flagship XTR M9200 race group, DEORE XT receives key technology and design cues from XTR, delivering a robust group designed to withstand the demands of real-world riding, and consistently redefining what's possible on two wheels. With the E-TUBE PROJECT Cyclist smartphone app, you can easily update the firmware and adjust the settings for the electronic shifting and the electric support modes. This allows you to get the best out of your bike - with customised settings just the way you want them.
