The new electronic Shimano XTR Di2 is ready to revolutionize shifting on mountain bikes. It is the first MTB shifting system that changes gears with unprecedented precision at the touch of a button. The strengths of the electronic shifting include fast, accurate, and smooth gear changes triggered by pressing a button. And this is not just in nice weather, but also under extreme conditions like heavy rain, mud, and snow. Programmable shifting layouts and the new unique Synchro-Shift are additional advantages of the electric shifting. The wiring is almost maintenance-free compared to traditional cables and simultaneously ensures a clear innovative cockpit design. Synchro-Shift allows shifting with just one button: chain changes at the front and rear with a single switch. Intelligent technology automatically provides the most efficient chainring/cassette combination. There are two different tested shifting layouts available. Switching between these or manual shifting is possible at any time, even while riding. Of course, personal settings can also be programmed.
