Shimano Dura-Ace Di2 R9270 with Power Meter Groupset

The DURA-ACE Di2 groupset is the result of Shimano’s ongoing passion for technology. This is reflected in every single component in the groupset. All components are joined together to work as one, reinforcing each other for unparalleled performance.

For the new DURA-ACE Di2 groupset, Shimano has improved upon each and every individual component. Together they form a truly superior groupset. A perfectly balanced total system. Improving performance by maximizing efficiency: that’s how Shimano is able to ensure the best for cyclists with the highest demands.

In addition to traditional “Full” Synchro Shift, riders can optionally select “Semi” Synchro Shift. This intuitive new mode automatically reacts when the rider shifts from one chainring to another, automatically shifting the rear derailleur to minimize the gear step, thus preserving the rider’s rhythm.
