ULTEGRA 8100: Join the Pursuit of Next Level Speed
Shimano's new ULTEGRA line-up dives into what is ready behind the science of speed with real-world applications. Following in the footsteps of the DURA-ACE design philosophy, and using many of the same product designs, including the new addition of the 12-speed rear, ULTEGRA is joining the pursuit of next level speed.

Wheel System: Aerodynamics, Rigidity, & Lightweight
The last pillar in ULTEGRA's development is the final point between the rider's input and the speed output. For the first-time ever Shimano has introduced a full carbon tubeless disc brake wheel line-up at ULTEGRA level.
Much like the new DURA-ACE wheels, performance comes from the balance of three factors - drag reduction without sacrificing control, driving force rigidity, and light weight construction - across three full carbon tubeless options.

C50: The All-Rounder
The C50 is the all-rounder of the R8170 range, with a great balance of drag, lateral and driving rigidity, periphery and overall weight and controllability.
