Shimano Dura-Ace R9270 Di2 2x12 Speed 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. This kit includes a crankset, front derailleur, rear derailleur, cassette, shift/brake levers, disc brake calipers, rotors, chain, battery, Di2 wires, and an internal battery charging cable.
- The Dura-Ace FC-R9200 crank performs two vital functions; transferring your pedaling effort into the drivetrain and ensuring the fastest, most precise front shifting available
- The CS-R9200 11-30t 12-speed cassette features larger driving cogs to maximize drivetrain efficiency and create compatibility with both Shimano 11 and 12-speed freehub bodies
- The FD-R9250 front derailleur offers ultra-fast shifting (45% quicker than FD-R9150), and features a small, lightweight design
- The Dura-Ace RD-R9250 integrates the system charging port and a wireless connectivity unit to deliver super fast, precise shifting, while also featuring a single cage length that shifts cassettes from 11-28 to 11-34
- ST-R9270 dual control levers offer wireless shifting for fast, precise gear changes, and bring enhanced modulation and control to every ride by employing Shimano's proven SERVO-WAVE ACTION technology
- The BR-R9270 mono-body caliper drops weight while also providing increased pad clearance, ensuring a quieter ride
