When developing the Ultegra R8100 series, Shimano took a holistic and 100 % performance-oriented approach, because great speed means great responsibility. Faster than ever before, the 12-speed road groupset scores with unparalleled control and comfort anytime and anywhere – whether in an everyman race, on the hunt for a personal best time or on a companionable ride.
As with the Dura Ace R9200, not only does Hyperglide+ make its way into the Ultegra's components, also its Di2 parts rely on Wireless technology to simplify operation and ensure smooth shifting.
