Fresh cables and housing feel great, don't they? Like your drivetrain is brand new. As sure as the fizz follows the plop, however, those housings get contaminated and make your drivetrain feel old and worn out a few weeks later. Sealed cables and rubber ferrules are not the solution, electronic shifting is. 

Shimano's XTR Di2 9050 Rear Derailleur might also be the difference between the first and second step on the podium. Shorter lever throws, instantaneous derailleur movement, and greater ability to shift under power are all advantages bestowed by the most advanced mountain bike technology available. All of Shimano's high-end derailleur features are present, including unbeatable Shadow RD+ chain stabilization and ultra narrow profiling to steer clear of obstacles. Sealed ceramic pulley bearings spin inside a carbon outer cage, which is attached to a carbon knuckle. Ultra-stiff, forged plates shift fast and accurately in any situation. 

Shimano's Di2 9050 system provides unbelievable shifting performance. 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, while not having to worry about the shifting that accompanies such range sounds even better, you'll be happy to know that the 9050 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. 

Eliminate the vagaries of cable-actuated shifting from your rides, and step up to a Di2 system drivetrain for flawless drivetrain performance. Di2 delivers hassle-free, maintenance-free operation that's more powerful and accurate than anything possible from traditional systems.
