Returns Simplified.Shimano Ultegra Di2 R8100 12V Group, The new Shimano shifting systems use wireless technology where needed, both for everyday activities and to maximize performance. By freeing the shift levers from connections to the back of the bike, a clean cockpit is created, simplifying the construction process. Additionally, connecting the derailleurs to an internal battery ensures absolute reliability, maintaining stable tension and improving the already lightning-fast Shimano shifting speed that has made Di2 a benchmark for WorldTour professionals. An integral part of the new Shimano 12v road range, the FC-R8100 crankset is rooted in Shimano’s legendary efficiency in chainring and drivetrain systems. With new refinements for ultra-smooth 12v shifting, the Ultegra crankset is now offered in lengths from 160 to 175 mm, providing greater performance and adaptability for those with a smaller physique, for triathletes, and for specific biomechanical needs. Shimano HYPERGLIDE+ cassettes have revolutionized off-road cycling with perfectly smooth shifting regardless of the selected gear. Today, technology can revolutionize road cycling. Even under maximum loads uphill or near the finish line, there is no longer a need to reduce pressure to shift gears. In any gear, Shimano Ultegra R8150 drivetrains maximize efficiency thanks to larger sprockets and are compatible with existing 11v rear hub bodies. All this while moving to 12 speeds and without increasing weight, the Ultegra CS-R8100 cassettes are the new paradigm of shifting for road bikes. With the fastest and most precise shifting on the market, the new Ultegra R8150 12-speed derailleur is more versatile than ever thanks to a single cage length option compatible with 11-28, 11-30, and 11-34 cassettes. Combining Shimano’s new DI2 platform and the road incarnation of Hyperglide+, the Ultegra R8150 derailleur moves with the fastest and smoothest action on the market. The new Shimano Ultegra ST-R8170 brake levers offer better modulation and control for any situation, thanks to Shimano’s proven SERVO WAVE technology. The brand new DI2 platform, used on both Dura-Ace and Ultegra, frees the shifting commands and offers the fastest and most reliable wireless shifting in the world. Your time on the bike is precious, and Shimano can make it even better. The Ultegra R8170 disc brake caliper creates new levels of control for road cycling, with better modulation and a quicker initial brake point. Despite its smaller structure, the system is incredibly quiet and maintenance is simplified.
