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.
The Shimano 105 shifters feature a re-designed internal shifting mechanism that has been optimised thanks to the advancement in professional-level drivetrains such as Ultegra and Dura-Ace. They mirror the performance of the higher-level components in the Shimano drivetrain line-up and provide exceptional shifting and brake performance while also being superbly comfortable and efficient to use. Easy, Fast, Comfortable Shifting and Braking Performance The Shimano 105 11 speed shifters have a great range of reach adjustment and the internal cables are extremely easy to access if adjustment or maintenance is required in the future. The updated ergonomic design features a new front-lever curve profile, which provides even faster and more comfortable shifting and brake engagement; it ensures performance is always at 100% and that every gear change and brake-pull feels natural and efficient.
