Product information "Shimano Dura Ace Di2 RD-9250 12-fach"
Shimano Dura Ace Di2 RD-9250 12-fach
The 12-speed RD-R9250 rear derailleur is the central element of Shimano's top-of-the-range Dura-Ace Di2 road bike group when it comes to semi-wireless and fully wired shifting.
It is mainly made of aluminum and carbon and therefore has a weight saving of almost 50 grams compared to the Ultegra model. RD-R9250 has even more to offer than a conventional rear derailleur, because in the disc brake variant it communicates wirelessly with the shift/brake levers via the built-in wireless chip.
In the case of the rim brake variant with cable connection to the STIs, it is responsible for coupling the components. This is done via a function button, which is also used to set the rear derailleur. You can also use the button to check the battery level, change the shift mode from manual to synchro and semi-synchro shift and establish a Bluetooth connection to a bike computer or smartphone. An LED display will help you.
