Drivetrain System An integral part of Shimano's 12-speed road lineup, the Ultegra R8100 group set builds upon Shimano's legendary front shifting and transmission efficiency.

Wireless Cockpit Shimano's Ultegra ST-R8150 brake levers bring enhanced modulation and control to every ride by employing Shimano's proven Servo Wave technology. The all-new Di2 platform, used on both Dura-Ace and Ultegra, untethers the shifters while delivering the world's fastest, most reliable wireless shifting.

Brake System The Ultegra R8150 disc brake caliper brings a new level of control to the road cycling world with enhanced modulation and a quicker initial braking point. Despite its smaller construction, the system is quieter than ever and easier to maintain.
