Shimano Dura-Ace Di2 9180 Hydraulic Disc Brake/Shift Lever

The Shimano Dura-Ace Di2 9180 Hydraulic Disc Brake/Shift Lever is built for triathlon and time trial riders who need precise shifting and confident braking without ever leaving the aero position. Dual shift buttons — one on each side of the lever blade — let you move through the cassette without breaking your grip or your posture. Hydraulic disc braking delivers consistent stopping power regardless of conditions, while Di2 electronics handle the shifting with a clean, mechanical exactness that cable systems simply can't replicate.

The lever integrates E-Tube wiring with internal cable routing, keeping your cockpit uncluttered and aerodynamically clean. A configurable multi-shift function lets you tailor the shifting behavior to your riding style — useful whether you prefer single-click precision or want to sweep through multiple gears in one input. Available individually as a left or right lever, so you can spec a 2x drivetrain with the left lever or run a right-lever-only setup for single-chainring 11-speed configurations.
