Shimano Ultegra R8170 Di2 Hydraulic Groupset Kit


The Science of Speed, Shimano’s design philosophy for its latest road groups, is comprised of five elements: a new Di2 platform, a refined interface, the addition of Hyperglide+, a category-redefining brake system, and a collection of new wheels. Here’s a quick rundown on how each of them contributes to faster, more efficient road riding. The launch of SHIMANO R9200 series DURA-ACE and R8100 series ULTEGRA is not simply an effort to make one-time bike setup easier or to unveil new technology for the sake of creating buzz. Instead, it represents a holistic approach that is 100-percent performance focused. 


Shimano's new shifting systems use wireless technology where it makes sense for both day-to-day life and ultimate performance. Freeing the shift levers from the rear of the bike cleans up the cockpit and simplifies the build process. Meanwhile, connecting the derailleurs to an internal main battery ensures absolute reliability by maintaining stable voltage while also improving Shimano's already lightning-fast shift speed that has made Di2 a staple of the WorldTour pro peloton.
