The Shimano Ultegra ST-R8170 Shift/Brake Lever delivers enhanced modulation and control, thanks to Shimano’s innovative SERVO WAVE technology. This cutting-edge technology untethers the shifters, allowing for a cleaner cockpit and less clutter, while still providing seamless performance. With feedback from professional riders, Shimano has crafted an ergonomic design that enhances comfort and performance.

The raised hood peak offers a more comfortable grip, optimizing brake control and improving overall ergonomics. The lever action is lighter and smoother, providing a more natural feel with every shift. Enhanced braking modulation, made possible by a larger control area, gives riders more precision when adjusting braking power. Whether wired or wireless, the ST-R8170 is compatible with a wide range of setups, and it can be paired with additional satellite shifters for increased versatility. Plus, the system’s high energy efficiency ensures long-lasting performance during long rides.
