Shimano Ultegra Di2 ST-R8050 2×11-Speed Shifters

The ST-R8050 Dual Control Levers bring the lightning-fast, programmable electronic shifting of the professional peloton to a high-performance rim brake package. Designed for the 11-speed era, these shifters are the choice for weight-conscious riders and rim brake traditionalists who demand the reliability of the Di2 ecosystem. By removing the hydraulic reservoir, Shimano achieved an ultra-slim, "wasp-waist" ergonomic profile that offers an incredibly secure and comfortable grip for any hand size. Utilizing the proven wired E-Tube connection, the R8050 ensures instantaneous shifts and centralized battery management. With tactile, distinct buttons and full compatibility with Synchro Shift technology, these shifters provide a digital precision that mechanical systems simply cannot match.

Key Features

• Ultra-Slim Ergonomics: Features the most compact hood shape in the Ultegra Di2 lineup, offering a natural and fatigue-free hand position.

• Wired Di2 Reliability: Direct E-Tube connection ensures consistent signal transmission and eliminated the need for individual shifter batteries.

• Tactile Shifting: Features a more defined "click" feel than previous generations, making it easier to shift even when wearing thick winter gloves.

• Synchro Shift Technology: Fully programmable to automatically control the front derailleur based on rear gear selection, maintaining a perfect chain line.

• Top-of-Hood Buttons: Hidden buttons under the hood covers can be used to shift derailleurs or control compatible Garmin/Wahoo head units.
