Shimano Dura-Ace R9270 12 Speed Disc Di2 Groupset
Precision. Speed. Uncompromising performance.
The Shimano Dura-Ace R9270 Di2 12-Speed Disc Groupset is the pinnacle of road cycling technology, engineered for elite racers and discerning cyclists who demand nothing but the best. Designed around wireless shifting, hydraulic disc braking, and ultra-lightweight efficiency, this flagship groupset brings unmatched responsiveness and control to every ride.
Race-Ready Innovation
Crafted with input from pro teams and fine-tuned for perfection, the R9270 Di2 system delivers flawless 12-speed gear transitions, a sleeker, more aerodynamic aesthetic, and intelligent ergonomics that improve power transfer and riding comfort. Whether you’re climbing, sprinting, or descending at speed, the Dura-Ace 9270 adapts instantly to your demands.
Unmatched Electronic Shifting and Brake Modulation
Shimano’s wireless Di2 platform eliminates cockpit clutter while delivering lightning-fast shift precision — no cables, no lag, no compromise. Each shift is executed with race-ready accuracy, allowing you to maintain focus and cadence under any conditions. Paired with refined hydraulic disc brakes, the R9270 offers intuitive braking feel with quieter operation and superior heat dissipation, even on long alpine descents.
Designed for Elite-Level Efficiency
Every component of the Dura-Ace R9270 system is engineered for minimal weight and maximum output. The Hollowtech II crankset balances stiffness and lightness, while Hyperglide+ cassette technology enables smooth, uninterrupted shifts under load — critical in race situations. Combined with optimised chain and derailleur profiles, the entire drivetrain is built to extract every watt of your effort.
Tailored Fit, Total Integration
Available in multiple crank lengths, chainring sizes, and cassette ratios, this groupset adapts to your ride style and frame geometry. The integrated internal battery and minimalist wire system support clean installation across compatible road frames with Di2 routing and flat-mount disc setups.
