Eagerly anticipated, the updated Shimano R8000 crankset has arrived. Featuring clear improvements in aesthetics and performance from the 6800 series, the Ultegra R8000 series has hugely benefited from the trickle-down technology of its big brother, the Dura-Ace R9000 model. This completely updated road bike chainset features lightweight crankarms, a hollow outer chainring, and a wider gear pitch for increased clearance on modern road frames that have wider rear dropouts and longer chainstays. Offering weight reduction without sacrificing stiffness, the Shimano Ultegra R8000 chainset enables a wide range of gear combinations to suit your every need. Paired with the updated front and rear derailleurs, your shifts will be so fast and reliable that you’ll almost question whether they happened at all. The beautifully shaped crankarms borrow their styling from Dura-Ace and will complement and enhance the aesthetics of your bike.
