Rear Derailleur -
The new Chorus rear derailleur benefits from the same technology and design of top-end Campagnolo products, incorporating the sophistication and performances of the 12-speed Super Record and Record.
With just a few changes in the materials used for its construction, like the external plate and derailleur cage in aluminum, the Chorus version produces exactly the same performance as the two more expensive groupsets with the addition of just a few extra grams.
Chorus brings with it the same technology as the next level up, like the new optimized trajectory on bigger cassettes and fantastic 3D EMBRACE technology.
The latest evolution in Embrace technology not only keeps the rear derailleur vertically aligned in the perfect position for each sprocket, it now makes the upper pulley wheel advance perfectly in the direction the bike is advancing.
3D EMBRACE technology and 12-teeth pulley wheels makes this rear derailleur suitable for all cassettes as the distance stays optimum on each individual sprocket, regardless of the cassette selected.
FEATURES & BENEFITS
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.

Front Derailleur -
The precise, extremely fluid movement of the front derailleur is achieved in part thanks to the new cables and their housing and in part because of the design and construction of the 2x12-speed front derailleur.
The new Chorus derailleur incorporates the same design that separates the upper from the lower semi-rod, eliminating the free stroke for more immediate, responsive upshifting.
Design of the 2x12 speed front derailleur and its trajectory angle mean wide tires measuring up to 32 mm can be used, while the new design of the cage and dedicated positions for each gear position ensure extremely precise and fluid derailleur performance.
FEATURES & BENEFITS
Braze on Fit
Upper semi-rod not connected to the lower one.
More effective precise movement and no contact with travel limit.
Cage designed to improve maximum cross-chaining situations.
The derailleur stops transmission contact and friction.
Ideal for wider tires.

Technology
X.P.S.S.™ is the embodiment of a project conceived with a very specific objective: to give the new Campagnolo 12-speed groupsets the best possible derailing performance. And the Campy Tech Lab™ has hit the mark once again.
The ascent and descent zones on the chainrings have been designed down to the smallest detail, using mathematical simulation programmes that reproduce the potential movements of the chain on the chainrings and draw the ideal angles of these. Repeated tests in the laboratory have enabled the speed and precision of derailings to be optimised. The profile of the chainring teeth has also been revised in order to render the action of these even more effective, and to ensure that they are perfectly in tune with the 12 Speed chain and the new front derailleur. All of these improvements enable a 25% increase in derailing under load and and a 20% the fluidity of shifting.
Indeed, the secret of this amazing result is the perfect combination and integration of all the components of the drivetrain: each of these is designed to work and function perfectly with the others - this is what enables you to enjoy the extraordinary performance that the new X.P.S.S. system offers.
AFTER MORE THAN 10 YEARS SINCE ITS INTRODUCTION THE ULTRA-TORQUE™ SYSTEM, IT IS STILL CONSIDERED, THE BEST PERFORMING CRANK-SET SPINDLE IN TERMS OF STIFFNESS, LOW WEIGHT AND EFFICIENCY OF POWER TRANSMISSION.
Campagnolo found a way to permanently conjoin the semi-axles of the bottom bracket to the respective crankset arms. This redesign made it possible to considerably reduce the lateral dimensions at the axle level and prevent annoying contact with the ankles when turning the pedals.
Assembly is simplistic: one single oversize bolt is enough to integrate the two semi-axles. With regard to torque transmission efficiency, this system is equally as effective as a single piece axle.
Furthermore, despite the narrow side profile, we have been able to position the bearings outside the bottom bracket shell, resulting in greater axle rigidity from the increased axle diameter. This breakthrough was obtained by using an ingenious mechanical system derived from many years' motoring experience in the rotation axle and engine shaft coupling sector: the Hirth joint.
In short , this is a joint with self-centring and self-aligning frontal teeth located in the middle of the bottom-bracket
axle where the ends of the semi-axles, integrated with the crankset arms, come into contact.
Campagnolo is constantly focused on the performance of its groupsets for all its ranges, from Super Record™ to Ekar™.
Its Micro Precision Shifting™ (M.P.S.™) System fully refl ects this philosophy: absolute precision, speed and a reduction of the distance covered by the chain when moving from one chainring to another.
Mechanical work on the outer chainring is proof of the obsessive attention to detail and the persistence of the engineers at our Campy Tech Lab™ who expect the maximum performance from all of Campagnolo’s products. The result is amazing and now moving from one chainring to another, even under load, will no longer be a problem!
Optimised design of the up-shift and down-shift zones and of the profi le of the teeth – enables fast and precise shifting in all types of conditions.

Hydraulic Ergo Levers and Calipers
12x Chorus Hydraulic Ergo levers and disc calipers for use with the disc brake groupset. These are now being supplied pre-filled with hydraulic fluid.
Campagnolo's fantastic ergonomics, that over the years have become a sort of calling card, have been even further improved with the latest introduction of the new 12-speed transmissions. the new shifters are not just ergonomic but also customisable, this new standard is embodied in the design of the Chorus levers. Apart from the aluminium brake lever with a coating that enhances its finish and feel the Chorus Ergopower Shifters are almost identical to those on the Super Record and Record controls. The new design of the new components makes them unique and versatile, with redesigned brake lever hoods, brake lever and bigger shift levers, together with the new Ergopower control "reach" that can be adjusted to suit hands of different sizes.
Campagnolo's tried and tested one-lever-one-action philosophy prevents unintentional shifts, even during tense competition or due to tiredness. The internal Ultra-Shift mechanism controls the 12-speed rear derailleur, letting the rider shift up by up to 3 Sprockets and down by up to 5 Sprockets in a single movement. Chorus controls deliver the same extremely durable, soft shifting performance of the other 12-speed groupsets thanks to new cables and their housings.
Features and Benefits
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.
Upshifting Lever Integration: More space under the control body when gripping the Ergopower control.
Disc Calipers: Flat mount disc only, to be compatible with the latest frame technology.
Technologies:
Customisable ergonomics, 3 levels of reach adjustment.
Vari-Cushion hood, different thicknesses allowing for greater grip, comfort and water dispersion.
