Campagnolo Chorus 12-Speed Groupset
Campagnolo Chorus 12-speed rim brake groupset has performed flawlessly for decades, a top tier groupset ideal for racing, riding and training stuffed with Italian passion and decades of engineering. Chorus uses the same technology and lever shape as Campagnolo Record, but utilises aluminium over carbon fibre materials.
Chorus Ergopower Levers
The aluminium levers of the Chorus 12-speed use trickle down technology from Campagnolo's Record groupset with the same air of power, stiffness and reliability. These controls allow riders to select two different lever-handlebar positions spaced to adapt to the size of the hand, whilst keeping braking efficiency constant. The Vari-Cushion technology offers an ergonomic, comfortable and safe support and grip. The “one lever-one action” feature assigns each lever one function to prevent shifting errors. The Ultra-Shift mechanism enables upshifting up to three sprockets at a time and downshifting a full five gears.
Chorus 12-Speed Chain and Cassette
The 12-speed drivetrain occupies the same space as 11-speed does — you can install a 12-speed cassette onto an 11-speed Campagnolo wheel — but with a narrower chain and sprockets. The shifting is very accurate and effective. The new Super Record™ 12 Speed sprocket sets feature thinner sprockets, tighter spaces and space-saving dimensions that are the same as those of the 11 Speed sprockets, meeting everyone’s needs with three 11/29, 11/32, 11/34 cassettes. The addition of the twelfth sprocket allows a linear upshift or downshift by a single tooth, up to the seventh gear, allowing the cyclist to find the perfect ratio for any situation.
Chorus Chainset & Ultra Torque
The carbon fibre Chorus 12x2 Speed crankset with unidirectional carbon finishing guarantees continuity with the finishings of the entire groupset, whilst maintaining the Ultra-Torque bracket system on the steel axle to ensure perfect transmission of power. The innovative design of the outer chainring ensures faster, quieter derailing owing to the contoured pin. The symmetrical design of the inner chainring teeth allows improved stability with chain crossovers. The double wheel sizing standards (112 and 145 millimetres) enable reducing the weight through greater use of carbon fibre. There are eight fixing screws for increased structure stiffness.
Chorus Rear Derailleur
The 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 the use of aluminium instead of carbon, found on the Record rear derailleur. The Chorus 12 Speed mechanical rear derailleur has been updated compared to the 11-speed groupset 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 cage has been designed to work with sprockets from 11 to 34 teeth, meaning that there is no need has different sizes of derailleur for different cassettes. The upper part of the Chorus 12 Speed mechanical rear derailleur gearbox is made of lightweight CNC aluminium, contributing to its robustness and lightness, while the stop adjustment screws at the back of the rear derailleur make adjustments very simple.
