Shimano Ultegra R8170 Di2 Disc Groupset

Shimano Ultegra R8170 Di2 Disc Groupset With technology trickling down from flagship Dura-Ace; Shimano’s Ultegra R8170 Di2 Disc Groupset is better than it has ever been before. It perfectly balances performance with value; and the components are slick; reliable; and only create a minimal weight penalty compared to Dura-Ace. Shifting is flawless; and faster than previous iterations; while operating almost silently. This is thanks to Hyperglide+ tooth profiles; meaning that the chainrings and cassette have an improved connection with the chain; essentially improving shifting under load; across the cassette. Adding in a 12th sprocket; progression through the gears is smoother too. Braking is equally impressive; and redesigned calipers provide more clearance between rotor and pad; reducing rubbing and scraping noises frequently heard in wet or gritty conditions. Servo Wave levers; which have been redesigned for improved ergonomics; speed up the initial travel so pad and rotor meet sooner; creating a more progressive feel. Aesthetics are sleek; with the semi-wireless system eliminating wires from shifters to derailleurs. The battery remains mounted in the seatpost or seattube; and this is wired to the derailleurs; while the charge port is now incorporated into the rear derailleur; so there is no junction box required. CR1632 coin cell batteries in the shifters provide 1.5 to 2 years of life and easy access to the port on the rear mech makes charging the rest of the system easy. There are plenty of configurations to choose from; including various crank lengths and both mid-compact and compact chainrings; making this groupset a fantastic option for the majority of riders looking to upgrade their bike to an electronic system.
