Shimano Dura-Ace R9270 12-Speed Di2 Disc Groupset

Shimano Dura-Ace R9270 12-Speed Di2 Disc Groupset Shimano’s Dura-Ace R9270 Di2 Disc Groupset is the pinnacle of the brand’s road technology; engineered for speed; smooth operation and sleek aesthetics. In this latest edition there are a number changes including better ergonomics in the shifters for improved functionality and comfort in all hand positions; increased braking modulation; faster shifting; and; of course; the additional 12th sprocket and the move to a semi-wireless configuration. The brains of the system; the R9250 Rear Derailleur houses the wireless hardware that communicates with the shift levers; and it’s hardwired to the front derailleur and battery; acting as the master link. It’s also the charging point; provides ANT+ connection to third party devices; features the button responsible for all Di2 operations and integrates an LED light for shift modes and battery charge levels. The longer cage length means that compatibility with 11-28 through to 11-34 ratio cassettes is fully supported. A carbon cage increases rigidity and lowers weight; while the corrosion-resistant cold-forged aluminium link plates of the derailleur body are strong to donate snappy gear changes. The overall profile is realised via Shimano’s Shadow concept to create a minimal silhouette; and a “fuse” function automatically activates during a crash to protect it from damage. DuPont Zytel pulleys complete the design; guaranteeing durability and damping drivetrain noise. Hyperglide+ technology in the sprockets and chain mean that the two mesh better; essentially improving shifting under load; across the cassette. R9200 has adopted the same XTR rotors as the MTB groupsets as they significancy reduce heat; while Servo Wave lever technology improves delivery of braking power and makes it easier to feather the brakes too. There are plenty of configurations to choose from; including various crank lengths and both mid-compact and compact chainrings; making this groupset a fantastic option for the majority of riders looking to upgrade their bike to the best available components.
