Shimano Ultegra R8000 11 Speed Chainset w/o BBEagerly 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.Hollowtech II TechnologyProviding the best balance of stiffness, strength, weight and rotating performance. The concept of Hollowtech II technology is focused on producing a superior crankset that will maximise a rider's power transfer. The rigidity of the crankset ensures pedalling efficiency while its weight, a key element of the crankset, you want light, aids in cycling longer distances over which the rider needs to pedal more. Naturally, Shimano strove for the optimum balance between the conflicting needs of stiffness while producing a lightweight crank. Hollowtech II technology is an ultra-lightweight hollow crankarm created by Shimano with the company's own proprietary forging technology that also maintains rigidity. The addition of Hollowtech II technology integrates the bottom bracket axle with the right crankarm for more stiffness and a weight savings to achieve a high-dimensional balance. Its outboard bottom bracket bearing system provides better weight distribution and more pedalling stability, allowing for more efficient power transfer.Features: Speed: 11 Speed Number of Chainrings: 2 Crank Construction: Hollowtech II (24mm spindle) Chainline: 43.5mm Q-Factor: 146mm Bolt Circle Diameter (BCD): 4x110mm asymmetric Bottom Bracket Included: No Redesigned crank arms for greater frame compatibility Lightweight crankarm design optimised for power-transfer efficiency Weight: 53/39T Option: 690g; 46/36T Option: 668gTechnologies: Lightweight crankarm design optimised for power-transfer efficiency. Minimal weight without sacrificing stiffness. Hollowtech II. Rider-tuned gear performance through various gear combinations. Redesigned FC for greater frame compatibility.
