The new electronic Shimano XTR Di2 is ready to revolutionize MTB gear shifting. It is the first MTB gear shifting system that changes gears with unprecedented precision at the touch of a button. The strengths of electronic gear shifting include fast, accurate and smooth gear changes triggered by pressing a button. And not just in good weather, but also in extreme conditions such as heavy rain, mud and snow. Programmable shift layouts and the new, unique Synchro-Shift are further advantages of electronic gear shifting. The wiring is almost maintenance-free compared to classic shift cables and at the same time ensures a clear, new cockpit design. Synchro-Shift shifting with just one switch: change the chain at the front and rear with just one switch. Intelligent technology automatically ensures the most efficient chainring/pinion combination. There are two different, tested shift layouts to choose from. You can switch between these or shift manually at any time, even while riding. Of course, personal settings can also be programmed.
