The future of shifting technology is finally available to us common folks. While Shimano's top-of-the-line XTR Di2 electric-shifting derailleur was amazing, it also came along with a pretty hefty $650 price tag. Now, you can get a Shimano Di2 derailleur for less than half of that, without sacrificing the buttery-smooth shifting that made the XTR so awesome. Yes, trickle-down technology is a beautiful thing! Now that the excellent (and affordable) Shimano XT Di2 8050 Rear Derailleur is available, you can expect to see electronic shifting becoming the norm rather than the exception.
With no cables to create shifter lag, gear changes occur the instant you press the lever. Each lever is customizable also, enabling you to assign up/down, front/back, and single or multiple shifts however you want. If the idea of keeping the untouchable gearing range a 2X or 3X crankset provides sounds great, and not having to worry about the shifting that accompanies such range sounds even better, you'll be happy to know that the 8050 rear derailleur works with the front, telling it when a shift is necessary. This takes the burden of front derailleur management out of your hands. Easy, automated, and efficient—this really is the future!
Eliminate the vagaries of cable-actuated shifting from your rides, and step up to a Di2 system drivetrain for flawless performance. Di2 delivers hassle-free, maintenance-free operation that's more powerful and accurate than anything possible from traditional systems—now for a fraction of the price.
