Keeping your ride under control in all road cycling situations, this set combines an Ergopower Super Record 12 Speed Disc Brake controller and a brake caliper for a more ergonomic, more precise, more powerful and easier to maintain set-up. Benefitting from many of Campagnolo's finest technologies including Vari-Cushion, One lever-One action, AMS Adjustment and an Ultra-Shift System, this model also offers a wide range of features and customisation for fine-tuning your braking and shifting performance. 12 Speed Ergopower Super Record Disc Brake Controller The mechanical controller for the Ergopower Super Record 12x2 Speed Disc Brake offers an ergonomic, comfortable and safe support and grip thanks to Vari-Cushion technology, essential for those who stay on the saddle for several hours. The controls' inner workings are a concentration of technology and experience, starting with the "one lever-one action" function, which assigns each lever a single function, helping avoid shifting errors at tired or distracting moments, and then continue with the multiple shifting options which allows up- or downshifting by up to 5 sprockets at a time thanks to the Ultra-Shift mechanism. This function allows you to maintain cadence even in case of sudden changes of incline or rhythm, with speed and ease as useful as it is surprising. Further useful features are the levers' adjustability, which, thanks to Reach Adjustment, enable a low grip on the brake lever, helping those with smaller hands; and AMS Adjustment, which enables braking power modulation, using the dedicated adjusters. The Super Record Disc Brake levers are engineered with a double curvature for improved grip and are lightened with two slots that are added to the one dedicated to Reach Adjustment. Campagnolo Caliper The flat-mount Campagnolo brake caliper ensures powerful, modular braking in any situation owing to pistons measuring 22mm in diameter. The pad return is now optimised to ensure that there is no friction when the brake lever is released. A special metal plate positioned between the pad and the caliper piston cushions the vibrations during braking. The Campagnolo brake caliper is designed to be mounted together with the disc chosen by the rider (available separately) and to always guarantee the highest level of performance. Careful attention was given to making maintenance and assembly operations easy: the pads have wear indicators and replacing them is facilitated by the absence of physical return springs. Additionally, work was done on the insertion of the disc in the caliper to make changing the wheel easier and faster. Technologies: Controller Technologies Comfortable Body: The controls enable a solid, safe grip when pedalling out of the saddle or gripping high on the handlebar. Rapid Shifting: Immediate shifting engagement enables activating the front derailleur with minimum effort and in any hand position on the bar. Multiple Action: An unplanned ascent, a sudden jerk: it takes barely a moment to find the right ratio owing to the multiple action of the controls. Ergonomic: The shape of the body and the possibility to adjust the reach enable all cyclists to use these controls, regardless of the size of their hands or fingers. Customisable: 3 levels of reach adjustment. Upshifting Lever Integration: More space under the control body when gripping the Ergopower control. Disc Caliper: Flat mount disc only, to be compatible with the latest frame technology. Maximum Smoothness Cables: Updated cable set maintains exceptional smoothness far beyond those of the competition, maximum performance longevity. Superior Alignment: Braking lever pivot aligned with slant of ergo power, more efficient power transfer requiring less energy from rider's hand. Upgraded Brake Lever: The result of meticulous studies (double curve brake lever, updated form outward curve). Vari-Cushion Hood: Different thicknesses allowing for greater grip, comfort and water dispersion. Enlarged Shifting Paddles: For instant reaction access. Ultra-Shift System: Up to 5 sprockets in downshifting, up to 3 in upshifting.   Caliper Technologies Standard Flat Mount: Fully compatible with flat-mount frames. 22mm Pistons in Phenolic Resin: Braking force and thermal isolation. Piston-Caliper Connector: The return action of the pistons is now optimised, rapidly returning the pads to their position and thus ensuring an overall clearance between pad and disc of 0.4-0.8 mm, with no risk of accidental contact. Interchangeable Spare Parts: Pads, cylinder, screws, bolts (same for all calipers): Fully compatible and optimised spare parts, making maintenance practical. Wear Indicator: It is very easy to see when the pads need to be replaced. Rounded Brake Pads: These facilitate disc insertion and speed up wheel changing. Anti-Vibration Plate: Optimal braking without vibrations. Two Fixing Screws: Rapid installation and maintenance.

Campagnolo Potenza HO Road Shifter and Disc Brake - Black - 140mm Rear Caliper, Black
  • £335.99

Campagnolo Potenza HO Road Shifter and Disc BrakeThe Campagnolo Potenza HO Shifter + Caliper provides exceptional braking power and shifting responsiveness. The level of speed and performance that is offered by many shifters and brakes on the market means nothing if the rider is not in control. The Potenza Ergopower features fantastic ergonomics meaning the shifting and braking commands feel natural in your hands and always ensure that you are in complete control in every situation.Comfortable and Consistent GripThe shifting controls and braking mechanisms have undergone in-depth studies to find the sweet spot for comfort and consistent grip over a long-distance ride. The ergonomic design also focus' on the natural motion of the human hand, meaning you can access the brake levers from above or below the hoods and will still provide exceptional braking power. Likewise, the up-shift and down-shift levers move in motion with how the human hand functions, making the whole process of using an Ergopower lever a pleasing and effortless experience.Features:Material: AluminiumShifter Type: Power-Shift mechanicalBrake Type: HydraulicLever Ergonomics: ErgopowerWeight: 370gTechnologies:Multishifting: Multi-shifting technology makes it possible to smoothly shift 5 gears down the cassette and 3 gears up by simply holding down the shift lever.Ergopower: Ergonomics: The shape of the shifter body conforms to your hands perfectly. The body of the control reproduces exactly the asymmetry of the human hand. This increases the contact with the palm and allows for various riding positions, ensuring maximum safety in all riding positions. Comfort: The shape allows you to easily reach the levers, regardless of your riding position and the size of your hands. The studies conducted on the position of cyclists' hands, showed three different steering positions depending on the course and the steering style. Based on these studies, Campagnolo created the exclusive form of the Ergopower controls that enable you to steer with safety and comfort. In addition, the special insert for large hands increases the distance of the levers by 8%, creating sufficient space for braking and shifting, always ensuring with maximum safety. The geometry of the hoods combined with a material of variable density that is stretchy, hypoallergenic and absorbs vibrations, enables you to stay in the saddle for many hours without hand fatigue. Effective Braking: The lever's Power-Shift shape lets you squeeze the brakes with greater power. It allows you to brake powerfully and promptly even when the hands are gripping high up around the hoods. Buy Campagnolo Components from Chain Reaction Cycles, the World's Largest Online Bike Store.

  • RRP £432.99
  • Saving you £25

Campagnolo Chorus Ultra Torque 11sp Double ChainsetThe completely redesigned chainset represents increased rigidity as well as fresh and cutting edge aesthetics.The new version uses a 4 arm spider design which makes for one single crankarm for all chainring options thanks to its unified bolt pattern. Gone are the days of having a dedicated bolt pattern for standard chainrings and another for compact rings. No longer will changing from traditional to compact, or vice versa, translate into the obligatory purchase of a completely new chainset. The new bolt pattern allows for all 3 chainring standards 53/39, 52/36 and 50/34 to be built upon the same chainset. Changing between compact and standard is now as easy as changing 8 bolts and two chainrings. While the new 4-arm bolt pattern makes for a much more practical design that offers the cyclist a more versatile component, the Campy Tech Lab was dedicated primarily on increasing performance characteristics.The new design incorporates a 8 bolt pattern with a spider arm design that not only holds the chainring in place by way of the bolt but also supports the chainring and in doing so, increases system rigidity. In addition to completely redesigning the spider, Campagnolo engineers dedicated a great deal of energy towards a completely new crankarm that is a great deal stiffer than previous versions. Add this new highly rigid crankarm to the new four-arm spider design and you have a complete chainset that not only excels at transferring power more than any previous version but one that is also more versatile with respect to gearing.Features: BCD: Inner: 112mm; Outer:145mm Weight: 684gBuy Campagnolo Components from Chain Reaction Cycles, the World's Largest Online Bike Store.
