With the Dura-Ace Di2 groupset, Shimano demonstrates how the reinvention of their components has the ability to transform the way we ride. In the reform of Shimano's Dura-Ace line, it makes sense that the brand would update their Dura-Ace ST-R9250 Shifter to mimic the technology found in their front and rear derailleurs. This shifter features refined ergonomics with an optimized hood shape and texture for better bike control and increased confidence when we're racing. Quick and intuitive shifting comes from a clearly defined click feeling with the shift lever, and a wired connection ensures reliable performance for every ride. We also like that this shifter features E-Tube technology, which allows us to fully customize our shifting preferences and makes for a clean setup. This is the shifter we turn to when we want to be riding and racing with confidence.
