Shimano Ultegra R8170 Di2 Disc Groupset - 12 Speed
The freedom of the open road, crisp mornings and fiery sunsets. Laughter filling the air and then trailing off. Nature, unfolding as you roll. Breathtaking vistas that stop you in your tracks. Coffee stops and camaraderie. Route prep and weather checks. Rain breaks and sunny bursts. Mad dashes. Racing each other to the top. And then kicking back...
 
Drivetrain System
An integral part of Shimano's 12-speed road lineup, the Ultegra R8100 chainset builds upon Shimano's legendary front shifting and transmission efficiency. With new refinements for seamless 12-speed shifting, the Ultegra crank is now offered in lengths from 160 to 175mm, bringining performance and improved fit for smaller riders, triathletes, and riders with specific biomechanic requirements.
 
Wireless Cockpit
Shimano's Ultegra ST-R8170 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 R8170 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.
