In creating the Ultegra R8100 series, Shimano adopted a fully holistic and performance-focused approach, understanding that with great speed comes great responsibility. This 12-speed road groupset is faster than ever, offering unmatched control and comfort in any situation—whether you're competing in a race, chasing a personal best, or enjoying a relaxed ride.
Like the Dura-Ace R9200, the Ultegra R8100 integrates Hyperglide+ technology into its components. Additionally, its Di2 parts utilize wireless technology for simplified operation and seamless shifting.
Sprocket ratios:
The conventional Hyperglide technology ensures smooth shifting upwards thanks to small shifting ramps, which guide the chain towards the next larger sprocket. Also Hyperglide+ uses this functionality but applies it in the opposite direction, too, preventing the chain from falling down when shifting downwards. The result is a smooth and consistent shifting in both directions, free of vibrations and without disrupting the cadence.
