Campagnolo Chorus 12-speed mechanical groupset

Bring genuine Italian racing heritage to your road or endurance bike with the Campagnolo Chorus 12 Spd Rim Brake (or Disc Brake) Mechanical Groupset. Benefitting from extensive trickle-down technology from Campagnolo's top-tier Super Record and Record lines, the Chorus 12-speed offers the exact same elite shifting performance and internal mechanics, utilizing slightly heavier, yet highly durable materials like aluminum in the derailleurs. It is the perfect choice for riders who demand premium performance, stunning carbon aesthetics, and precision engineering without the flagship price tag.

Known for its unrivaled ergonomics, the Chorus Ergopower levers feature Campagnolo’s legendary "One lever, One action" philosophy, preventing shifting mistakes even during intense efforts. The internal Ultra-Shift mechanism allows you to dump multiple gears at once—shifting up by 3 sprockets or down by 5 in a single movement. Furthermore, Chorus introduces a versatile 48/32T sub-compact crankset option and an 11-34T cassette, making it equally adept on grueling mountain passes and mixed-terrain gravel rides.

Key Features:

• Premium Carbon Construction: Features a stunning unidirectional carbon fiber crankset with an Ultra-Torque steel axle for maximum stiffness and power transfer.

• Ultra-Shift Technology: Allows riders to shift up to 3 gears up or 5 gears down in a single, fluid motion.

• Refined Ergonomics: The Ergopower levers offer an adjustable reach and updated hood shapes to accommodate any hand size perfectly.

• 3D Embrace Technology: The rear derailleur keeps the chain perfectly positioned on every sprocket, maximizing power efficiency and reducing wear.
