ULTEGRA R8000 offers a wide range of gear combinations (11-25T, 11-28T, 11-30T, 11-32T, 12-25T, 14-28T, 11-34T), brake systems (rim brakes and hydraulic disc brakes with Ice Technologies Freeza rotors), redesigned dual control levers and remote shifting options. Everything you need to tune your ride.
The center-piece of the ULTEGRA R8000 is the HOLLOWTECH II crank set. It offers weight reduction without sacrificing stiffness, transferring more of your power into speed. The beautifully shaped crank arm - trickled down from DURA-ACE - is a tribute to the aesthetics of your bike.
