Campagnolo Chorus Ergopower Ultra Shift 12S right gear shifter + caliper

The fantastic ergonomics that over the years have become a sort of calling card for Campagnolo, have been even further improved with the latest introduction of Super Record and Record 12-speed transmissions. Not just ergonomic but also customizable, the new standard is embodied in the design of the Chorus levers. Apart from the brake lever, constructed in aluminum but with a coating that enhances its finish, it feels almost identical to the Super Record and Record controls. Ergonomic characteristics, such as the new design of the brake lever hoods, the updated design of the brake lever and bigger gear levers make the Ergopower shifters extremely versatile and comfortable. The various positions possible for Ergopower controls mean they adapt better to different hand sizes.

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 option 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. Chorus controls deliver the same extremely durable, soft shifting performance of the other 12-speed groupsets thanks to the same cables and housings configuration.

Shifter features

• Comfortable support: the controls can be safely and securely gripped when riding out of the saddle or on the tops of the handlebars.
• Quick shifting: the immediate shifting allows operation of the derailleurs with minimal effort, from any position on the handlebars.
• Multiple shifting: a sudden climb, a lightning-fast movement: finding just the right ratio takes but a moment thanks to the multiple action shifters.
• Ergonomics: the contoured support and reach adjustment mean these controls can be used by all cyclists, regardless of the size of their hands and fingers.

Caliper features

• Standard Flat Mount: fully compatible with flat-mount frames.
• 22 mm pistons in phenolic resin: braking force and thermal isolation.
• Magnetic piston-caliper connector: pads return to position rapidly, guaranteeing an overall gap between the pad and disc of 0.4-0.6 mm and zero risk of accidental contact.
• Interchangeable spare parts: pads, cylinder, screws, bolts (same for all calipers). Fully compatible and optimised spare parts, making maintenance practical and reducing the number of components to keep on hand in the warehouse.
• Wear indicator: it is very easy to see when the pads need to be replaced (not included).
• 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.
• Pistons: 2.

One lever-one action
Lever 1 brake
Lever 2 up-shifting
Lever 3 down-shifting

These levers are natural and intuitive to use. A simple touch of the sifter follows the movement of the chain on the sprockets.

Ultra-shift™ system
The Ultra-Shift™ control by Campagnolo® is regarded by everyone as the fastest and most precise sifter on the market.
Thanks to the Ultra-Shift™ patented system, you can move the chain simultaneously up 3 sprockets and then 5 down. Furthermore, the lever design allows for an ever lighter shifting, whilst maintaining the "click" sound featured on all Campagnolo® controls.

Campagnolo brake caliper: powerful, modulable and reliable
The flat-mount Campagnolo brake calipers ensure powerful, modular braking in any situation owing to pistons measuring 22 millimetres in diameter. Brake pad return guaranteed by the magnetic system ensures that there is no friction at the time of brake lever release. A special metal plate positioned between the pad and the caliper piston, cushions the vibrations during braking.

The different Campagnolo brake calipers were designed to be mounted together with the disc chosen by the rider and to always guarantee the highest level of performance. It is indeed possible to choose the rear brake caliper with a disc measuring either 140 mm or 160 mm in diameter and to use a specific 160 mm front caliper. 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.

Flat Mount
Campagnolo disc brake calipers are suitable on all Flat Mount forks and frames. Thanks to this standard the assembly is allowed without converters or adapters. While the caliper is assembled directly on the fork, increasing a lot the stiffness of the complete system. This is the ideal configuration for racing. The Campagnolo solution needs only 2 bolts for assembling the caliper on the fork. This allows to leave out the two bolts that you can’t inspect.

Brake pads
Removing the pads you can immediately understand if you need to replace them. The replacement is needed when the thickness of the compound reaches the wear indicator at 1.5 mm.

Chamfered bottoms allow for easier wheel replacement because the rotor is helped from the pads shapes when entering in the caliper A metal sheet damps the vibrations coming from the braking phase. Semi-metallic formulation tuning provide the use in dry and wet condition without compromises.
