Description
Say goodbye to the days where spring and cable tension move chains from cog to cog. Utilizing a superiorly innovative digital technology, the Dura Ace Di2 Rear Derailleur functions by employing a drive motor that moves the chain from gear to gear making shifting not only more accurate, but a lot faster.
With the technology built into the Dura Ace Di2 Rear Derailleur your shifting becomes effortlessly smoother with less chain drop, where you'll get gear changes that are identical and precise every time as the computer control unit analyzes each shift. Aside from this, a built in saver function moves the derailleur inward under impact reducing the potential for damage in the event of a crash.
Fashioned with a carbon fiber cage and 11-tooth sealed bearing pulleys, the Dura Ace Di2 Rear Derailleur has a titanium fixing bolt with alloy and titanium hardware that allows the weight to be an amazingly light 222g and an expanded chain wrap accommodates a maximum 27 tooth cog for better compatibility with compact cranks.
