Shimano Ultegra R8000 11 Speed Chainset w-o BB - Black - 53.39t}, Black

  • Saving you £20

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.

Shimano Ultegra R8170 C50 CL Front Disc Wheel - Black - 700c}, Black
  • £349.99

  • Saving you £40

Shimano Ultegra R8170 C50 Carbon CL Front Disc WheelThe Shimano Ultegra R8170 C50 Wheel features a 50mm-deep full carbon tubeless ready rim with Shimano D2 rim profiling. This rim offers exceptional aerodynamic efficiency and agility while maintaining stability and control during strong cross winds. Suited to climbing sessions, long-distance fast events and epic endurance rides, this wheel features a centre lock disc rotor mount and is compatible with Shimano 11 and 12-Speed drivetrain systems.Balancing aerodynamics, weight, and affordability, the new Ultegra R8170 C50 front wheel is sure to inspire action on your group ride with its all-new tubeless carbon rim and updated, 12 and 11-speed compatible hub.Summiting climbs, carving descents, or cruising the flats, the new C50 is the jack of all trades among the new Ultegra R8170 wheel lineup. The tubeless, carbon rim features a 21 mm internal width that pairs nicely with wider, modern tyres while the HYPERGLIDE cassette body is compatible with 11 and 12-speed cassettes.Centre-Lock Disc Rotor MountThe Centre Lock system makes an easy rotor installation possible with a spline mount and a lock ring. The lock ring mounting system reduces the total working hours by shortening the amount of time of both installation and de-installation. In addition, the secure fixing by the spline mount enhances precision and rigidity while improving braking efficiency.D2 Aerodynamic Rim ProfileAerodynamic performance is affected by wind direction. To create the D2 rim, Shimano engineers considered both frontal and crosswinds, aiming to achieve optimal performance in real-world riding conditions. Extensive prototype testing, in the wind tunnel and on the road, proved that a wide rim shape with a deep tyre bed performs best across a wide range of conditions. At yaw angles ranging from 0 to 15 degrees, the Shimano D2 rim profile reduces air drag better than others aero shape rims. This rim design also boosts lateral wheel stiffness and offers improved vertical compliance for increased control, comfort and durability on the road.Shimano E-Thru Axle SystemThe tool-less type thru-axle skewer system optimizes rigidity and weight balance and enables easy operation with a reliable internal cam mechanism. The 15 mm thru-axle system is 15% stiffer torsionally and 25% stiffer in transverse shear than a traditional 9 mm quick release front axle system. High rigidity is secured while keeping the optimum weight balance. The E-Thru axle hub system minimizes the distortion of suspension while maintaining lightweight for riding around sharp corners at high speed.Features: Series: Ultegra R8100 Series Rim: Carbon Tubeless Ready 50mm height full Carbon rim Internal Rim Width: 21mm Shared rim profile with R9200 Dura-Ace wheels Improved aerodynamics Axle: 12mm E-THRU Disc Rotor Mount: Centre Lock Weight: 698gA 2-year warranty is offered with all Shimano products from Chain Reaction Cycles (3 years on Dura-Ace and XTR products).Buy Shimano Wheels & Tyres from Chain Reaction Cycles, the World's Largest Online Bike Store.
