The redesigned Ultegra R8170 Di2 dual control levers have an ergonomic design, precise brake modulation, and wireless electronic shifting. This trifecta lets you focus on the sprinting, descending, or joking with your riding partner.

These levers bring enhanced modulation and control to rides with Shimano's Servo Wave technology. The new 12-speed Di2 platform untethers the shifters while delivering the world's fastest, most reliable wireless shifting.
