Shimano Dura-Ace R9250 Di2 Groupset

The Shimano Dura-Ace R9250 Priority Pack Groupset features the components needed to deliver advanced drivetrain technology and shifting performance. Shimano’s wireless Di2 processing technology increases transmission speed and performance, offering reliable, fast shifts every single time. Dura-Ace R9250 is wired where it makes sense, featuring a central, multi-port battery that supplies stable, long-lasting power to both front and rear derailleurs. The drivetrain features Shimano’s Hyperglide+ technology, which was first developed for mountain bike applications, to offer ultra-smooth shifting, even under maximum pedaling load.
