Campagnolo Chorus DB Ergopower controls

The fantastic ergonomics that have become a calling card for Campagnolo over the years have been further improved with the introduction of the Super Record and Record 12-speed drivetrains and are continued in the design of the current Chorus brake/shift levers.

Apart from the aluminium brake lever, which has a high-quality coating, the Chorus Ergopower controls have features that are very similar to those of the Super Record and Record brake/shift levers. However, the design of the hand protection rubber, brake lever and shift lever as well as the Reach Adjustment function for individual adaptation to different hand sizes make the Chorus model unique and at the same time variable in use.

Campagnolo's proven "One-Lever-One-Action" philosophy prevents faulty operation even in moments of competitive tension or fatigue. The internal Ultra Shift mechanism is used to control the 12-speed rear derailleur, allowing up to 5 sprockets down or 3 sprockets up to be shifted in a single movement. The Chorus shifters offer the same extremely durable and smooth shifting performance as the two Record groupsets thanks to reworked cables or hoses and an optimised housing.

Campagnolo Flat Mount caliper

The Campagnolo Flatmount disc brake calipers ensure powerful and modular braking in any situation owing to its phenolic resin pistons with 22 mm diameter. This lightweight material provides proper thermic isolation to guarantee constant braking performance even in the long term

To reach the highest level of performance, the construction of forged aluminium provides the necessary rigidity and stiffness. The piston's return mechanism is optimised for a quick return of the pads to their position, cushioning the vibrations during braking and ensuring a total clearance between pad and disc of 0.4 to 0.8 mm without risk of accidental contact.

The caliper was also designed with accessibility in mind, keeping maintenance and assembly operations easy. Accordingly, the pads have wear indicators and replacing them is facilitated by the absence of physical return springs. Even the insertion of the disc into the caliper could be improved to make changing the wheel easier and faster.
