Even-Faster Shifts & More Controlled Rim Braking
The Ultegra ST-R8150 Di2 Shifter/Rim Brake Levers have all-new ergonomics, precise brake modulation, and electronic shifting. With even-faster shifts, more controllable braking, an updated lever shape, and a very long battery life, these new shifters reset the industry standard, all at a more affordable price than Dura-Ace models. Unlike the disc brake version, these shifters can only be used with a wired Di2 connection
Shimano's new ST-R8150 brake levers bring enhanced modulation and control to every ride by employing Shimano's SLR-EV dual symmetric pivot brake caliper actuating tech and Dual Control Levers.
A new Shimano E-Tube Project App (version 4.0.0) offers intuitive operations for personalizing the Ultegra R8100 drivetrain. Offering a suite of customizable, riders can choose between different shift speeds, customize shift button mapping (what buttons perform which functions), program different automatic shift modes like Synchro and Semi-Synchro shifts, fine-tune shifting, and connect with third party bike computers.
