Why We Like The Dure-Ace ST-R9250 Shifter Set

The Dure-Ace ST-R9250 Shifters take advantage of Shimano's new wireless Di2 technology to bring us a claimed 58% faster rear shifting and 45% faster front shifting—all while retaining the crisp, reliable gear changes that we’ve come to know and love from Di2. These particular shifters are designed for cable-actuated rim brakes, and are meant to be paired with the rest of Shimano’s Dura-Ace Di2 9200 drivetrain.


  • Shimano goes for a wireless cockpit with new Dura-Ace Di2
  • Levers are designed for cable-actuated rim brakes
  • Redesigned for improved shifting performance and ergonomics
  • Reach adjustment for finding the perfect lever position
  • Ports for remote sprint shifters allow further customization
