The Dura-Ace Di2 R9250 Power Meter Priority Pack by Shimano - Your access to the Science of Speed

The Dura-Ace Di2 R9250 Power Meter Priority Pack gives you priority access to Shimano's brand new top racing groupset. It consists of a 2x12-speed power crank with 34-50 or 36-52 tooth increments, an electronic rear derailleur and front derailleur for semi-wireless shifting, and a flat-mount disc brake set. Of course, a rechargeable battery, a Quick-Link chain and a cassette with 11-30 teeth are also included.

Shimano has uncompromisingly designed the Dura-Ace R9250 for speed and performance. User-friendliness, efficiency and safety also played a major role in development. That's why the groupset works without cables at the crucial point, namely the interaction between STIs and rear derailleur. Cables are only used between the battery and the rear derailleur or front derailleur. The wireless protocol is extremely fast and reliable, which raises the shifting speed to a new level - with consistently high precision. A twelfth sprocket on the cassette in combination with a very clever gradation means that you have a wider gear selection at your disposal, and are optimally prepared for any terrain. In addition, Hyperglide+ technology familiar in MTB sport ensures smooth gliding of the chain even under loads. Conveniently, the Dura-Ace 12-speed cassettes are also compatible with older Shimano road freehubs. Last but not least, the disc brakes have been thoroughly revised and equipped with servo-wave technology. This way, the full braking power is not only available more quickly, but can also be modulated better. A simplified bleeding process and more free space for the brake pads are further advantages. The crank comes with integrated power measurement on both sides, which boasts an even higher accuracy than before, with a deviation of only 1.5 %. The power meter functions with a built-in battery that is charged via the same cable as the derailleur battery.
