Why We Like The Ultegra ST-R8170 Di2 12-Speed Shift/Brake System

Getting us up to speed and back to a halt very quickly is the Shimano Ultegra ST-R8170 Di2 Shift/Brake System. This combo system includes light and responsive flat-mount calipers with an accurate wireless Di2 drivetrain. The hoods on the shifters have been made to be even more aerodynamic to quickly cut through the wind.
