Description
Shimano Dura-Ace Di2 R9200 12-Speed Disc Groupset
The Shimano Dura-Ace Di2 R9200 Groupset brings Shimano’s flagship electronic shifting and hydraulic disc braking technology together in a complete 2×12-speed road cycling drivetrain package. Developed for competitive road riding, racing and performance-focused cycling, the R9200 series combines fast, precise Di2 gear changes with a wide-range HYPERGLIDE+ drivetrain and refined braking control.
Featuring Shimano’s semi-wireless Di2 system, the Dura-Ace R9200 groupset uses wireless communication between the ST-R9270 shift levers and the derailleurs, helping create a cleaner cockpit without compromising the reliability of a wired connection between the front and rear derailleurs and the internal battery. This package includes a 52/36T double chainset, 11-34T 12-speed cassette, hydraulic disc brakes, electronic derailleurs and the necessary Di2 battery, cables and wiring. Available with either 165mm or 170mm crank arms, it provides a high-performance upgrade for compatible road bikes.

Fast and Precise Shimano Di2 Electronic Shifting
At the centre of the Dura-Ace R9200 groupset is Shimano’s Di2 electronic shifting system, engineered to deliver rapid and accurate gear changes with minimal effort at the controls. The RD-R9250 rear derailleur and FD-R9250 front derailleur work together to manage the 2×12-speed drivetrain, providing consistent shifting across both chainrings and the cassette.
The semi-wireless system allows the ST-R9270 shift levers to communicate wirelessly with the drivetrain, reducing the need for cables around the handlebars. The front and rear derailleurs remain connected to the BT-DN300 internal battery using Shimano EW-SD300 E-Tube wires, providing a dedicated power supply for the electronic shifting system.
HYPERGLIDE+ 12-Speed Drivetrain
The supplied FC-R9200 chainset features a 52/36T chainring combination, paired with a Shimano CS-R9200 11-34T 12-speed cassette. This setup provides gearing suitable for fast road riding while retaining lower ratios for climbing. The 52T outer chainring supports higher-speed efforts on flatter roads and descents, while the 36T inner chainring and 34T largest sprocket provide a more manageable gear for longer or steeper climbs.
Shimano’s HYPERGLIDE+ technology is designed to improve chain engagement and maintain smooth shifting when changing gear under pedalling load. The included CN-M9100 12-speed chain completes the drivetrain, providing compatibility with the supplied Shimano 12-speed components.
ST-R9270 Wireless Shift Levers
The Shimano Dura-Ace ST-R9270 dual-control levers combine electronic shifting with hydraulic disc brake operation. Their redesigned ergonomic shape is intended to improve hand positioning and control, particularly when riding on the hoods for extended periods or adopting a more aerodynamic road riding position.
Wireless communication between the levers and the Di2 drivetrain also helps reduce external cabling around the cockpit, making the system particularly appealing for modern performance road bikes with integrated handlebar and cable-routing designs.
Hydraulic Disc Braking with SERVOWAVE Technology
The Dura-Ace BR-R9270 hydraulic disc brake callipers are designed to provide controlled, responsive braking for demanding road riding. Shimano’s SERVOWAVE technology changes the relationship between lever movement and brake pad movement, allowing the pads to approach the rotor quickly before providing greater control as braking force increases.
The redesigned braking system also incorporates increased pad clearance to help reduce unwanted rotor contact and associated brake noise. This groupset includes front and rear hydraulic brake callipers, brake pads, hoses, mineral oil and 160mm/140mm disc brake rotors.

Crank Length Options
The Shimano Dura-Ace FC-R9200 chainset is available in two crank lengths within this groupset package: 165mm and 170mm. Both options use the same 52/36T chainring combination. Crank length selection should take account of rider fit, pedalling position and personal preference.
Compatibility and Installation
This groupset is designed for compatible road bikes using a Shimano 2×12-speed Di2 drivetrain and hydraulic disc brakes. Before ordering, check your frame’s front derailleur mounting arrangement, bottom bracket standard, rear wheel freehub compatibility, brake mounting and rotor requirements, and the routing and installation requirements for the Di2 components. The package includes the electronic battery and specified wiring, but does not include a bottom bracket. A compatible bottom bracket must be purchased separately.
