Campagnolo Record 12 Speed Rear Derailleur (11/34)
  • £214.99

New mechanical Record 12 Speed rear derailleur: precision, lightness and versatility for use with the disc or rim brake groupsets.Designed to improve performance and function in every aspect, the new Record 12 Speed mechanical rear derailleur has an innovative shape that envelopes the sprockets better thanks to 3D Embrace technology, creating a double effect: allowing the chain to maintain optimum traction at all times, thus increasing the speed, power and precision of shifting; and ensuring that the derailleur is always kept an optimal distance away from the sprockets.The new cage has also been optimised to work with sprockets from 11 to 34 teeth, allowing a single version to be maintained for all available sprocket sets. The upper part of the new Record 12 Speed mechanical rear derailleur gearbox is made of carbon fibre-reinforced techno-polymer, contributing to its robustness and lightness, while the stop adjustment screws at the back of the rear derailleur make adjustments very simple. Technologies:Upper body in ULTRA-LIGHT technopolymer reinforced with UD Carbon Fibre,3D Embrace Technology: Movement of the rear derailleur is designed to make the chain embrace more teeth per sprocket to guarantee maximum traction,Optimised trajectory: Movement of the rear derailleur means that the upper pulley wheel is at constant distance to the sprocket in use,12-tooth pulley wheels: Perfect for cassettes that have a wide range of teeth,Optimised return spring: This guarantees constant chain tension regardless of road vibration,Versatile Hanger System: Standard or Direct mount hanger, perfect compatibility of rear derailleur with any frame: disc or rim, direct mount or classic hanger,. Key Features: Constant precision: On rough roads, the spring positioned between the upper body and the pivot absorbs the vibrations, ensuring the chain always rests properly on the sprockets, The pulley wheels on the 12-tooth derailleur cage allow the chain to move more smoothly,The initial position of the rear derailleur can be adjusted to suit any cassette,Easy wheel replacement: The rear derailleur is positioned further back, making it easier to slide the wheel out and replace it,Weight: 216g.

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.
