The Shimano Ultegra ST-8070 Di2 Shift/Brake Levers offer an updated and improved design, providing a Di2 shifter that offers more intuitive shifting with hydraulic braking capability. The improved ergonomics of the ST-8070 feel great in all positions, offering a solid, stable platform and reach-adjustable lever operation. The shift buttons themselves have received an update, featuring a clearer separation between buttons with a more defined response on activation making it easy to locate and operate, even with heavy winter gloves. Further, each shift button can be programmed for multi-shifting via Shimano's e-Tube project.
For those riders building up a new bike or upgrading an existing one, this offering includes the Shimano Ultegra R8070 hydraulic brake caliper. Marking the first hydraulic disc brake caliper to bear the Ultegra name, this flat mount disc brake caliper provides reliable, predictable braking with superior modulation and heat management over previous Shimano hydraulic calipers.
The Shimano Ultegra ST-8070 Di2 Shift/Brake Lever is compatible with 2x11 speed drivetrains and hydraulic brake systems. Claimed weight: 180 grams per shifter. 280 grams per caliper.
