The Shimano Dura-Ace ST-9070-R is a right brake and electronic shifter combo designed for road bikes using the 11-speed Dura-Ace Di2 9070 groupset. It features electronic shifting technology, providing precise gear changes with minimal effort and integrates the brake lever for a clamp-on handlebar fit. Constructed with a composite body and carbon lever material, it offers durability and a lighter weight ideal for road cyclists seeking electronic shifting.

The shifter supports seamless 11-speed shifting and is compatible with other 9070 series Di2 components and Shimano’s E-Tube system for firmware updates and customization. Its smaller lever diameter also makes it suitable for riders with smaller hands. Installation requires proper tightening torque on carbon or alloy handlebars, and compatibility is limited to Shimano 11-speed Di2 electronic groupsets. This shifter is targeted at road cyclists who prioritize consistent electronic shifting performance and compatibility with Shimano Di2 systems.
