Your access to the science of the screw The priority pack Dura-Ace Di2 R9250 you women a priority access to all the new Shimano group of course. It is composed of a 2x12 screw crank with increments of 34-50 or 36-52 teeth, an electronic rear slider and a forward slider for a semi-without thread change of screw, as well as an ensemble de freins à disque à montage plat. All in all, a rechargeable battery, a rapid mail chain and a cassette of 11 to 30 teeth are also included. Shimano has built the Dura-Ace R9250 without compromising life and performance. Ease of use, effectiveness and security also play an important role in development. This is why the group works without cables at a crucial point, to know the interaction between STI and screw boxes. The cables are not used between the battery and the screw box or the screw box. The protocol without the wire is extremely quick and easy, which brings the switching speed to a new level, with high and constant precision. A double pinion on the cassette, associated with a very intelligent gradation, means that you have a choice of larger screws and that you are perfectly prepared for all terrains. Furthermore, the Hyperglide+ technology, common in VTT sports, guarantees a smooth glide of the chain under charge. Ideally, the Dura-Ace 12 screw cassettes are equally compatible with the older Shimano wheels. Indeed, the drivers on display are soigneur and equipped with Servo-Wave technology. In this way, the full power of braking is not always available more quickly, but can only be used in the same way. Other advantages include a simplified purge process and more free space for brake plaques.
