Dura ACE DI2 R9270 Shimano Group

The SHIMANO Dura-Ace Di2 R9270 2x12V groupset with 11/30T cassette represents the pinnacle of technology and innovation for road bikes. After years of research, Shimano has developed its fastest and most advanced drivetrain to date. This 12-speed groupset is designed for riders looking to push their limits, with each component optimized to shave precious seconds off races or intense rides. Thanks to Di2 technology, every gear change is instantaneous and precise, even in the most demanding conditions. The compact and ergonomic shift lever provides optimum control in all conditions, providing increased comfort and perfect control, regardless of the riding position.

The system offers a considerable advantage in preserving the rider's energy, allowing them to concentrate on the pleasure of the ride and the effort required without worrying about drivetrain failures. Gear changes are automatic thanks to a switch, eliminating the lever travel required for mechanical systems. This feature is particularly useful for adjusting gears to suit varying road conditions.

Shimano D-FLY bridges the gap between component technologies and Di2 software. D-Fly enables connectivity between Di2 systems and ANT+/Bluetooth®LE compatible accessories such as computers/GPS and lights. It also offers wireless connectivity with Shimano’s E-TUBE PROJECT Cyclist for smartphones, allowing you to customize your shifter configuration, check for firmware updates, and troubleshoot component failures.

The sub-1:1 ratio of the SHIMANO Dura-Ace 12-speed drivetrain allows for more challenging climbs with greater control over your effort. The synchronized front derailleur ensures consistent pedaling and smooth shifting, while the E-TUBE PROJECT app allows for personalized tuning. Whether you're tackling the legendary roads of the Tour de France or climbing the hills of your region, the DURA-ACE R9270 is designed to maximize your speed and improve your performance with every pedal stroke.
