Wireless Di2 Shifting – Instant, Effortless, Precise
Shift with lightning-fast precision using wireless Di2 connectivity. Just a gentle press of the tactile button, no more than a mouse click, initiates an immediate, smooth gear change on the front or rear derailleur. Whether racing or training, you’ll benefit from friction-free, cable-free gear shifts that are both intuitive and ultra-reliable.
Designed for Comfort and Performance
Even with gloves or cold fingers, ergonomic button placement and tactile feedback ensure you never miss a shift. The drop-bar design mimics traditional mechanical STI positioning for a familiar feel while embracing the advanced functionality of Di2 electronic shifting.
Hydraulic Disc Braking with Servo Wave Technology
Built for superior stopping power, the hydraulic brake lever features Shimano’s Servo Wave tech, increasing braking force and modulation with minimal input, especially from the hoods. A hydraulic reservoir tank maintains consistent pad-to-rotor clearance for stable performance as your pads wear.
