The most revolutionary option of the new XTR is the so-called Synchro Shift. We can change the gears of both the front and rear derailleur with just one handlebar. The front derailleur tracks the rear gear ratio and, based on this, selects the most optimal gear on the crankset. This preserves the best chain line, and the cyclist does not have to worry about changing the front derailleur ratio. During the automatic change of the front gear ratio, the system will also make the necessary adjustment of the chain position on the cassette - we can define ourselves by how many laces. The gear map, i.e. the pattern according to which the system makes automatic changes of the front gears, can be switched while riding by pressing a button on the display. There are two predefined maps at the user's disposal, which can be modified by connecting to a computer. The same button can also be used to switch to fully manual mode.
