Campagnolo Chorus 12-Speed Crankset: Precision-Engineered Road Performance

Built for competitive cyclists seeking lightweight durability and responsive power delivery, this double-chainring system combines advanced materials with Campagnolo’s signature engineering.

Core Advantages
✓ Ultra-lightweight carbon fiber crank arms (686g total) reduce rotational inertia for explosive acceleration
✓ Proprietary Ultra-Torque spindle delivers 17% higher stiffness than standard road crank interfaces
✓ Asymmetrically contoured inner chainring (34T) enables smooth cross-chaining transitions up to 50% gear range expansion
✓ Hard-anodized aluminum chainrings withstand 40% more wear cycles than untreated surfaces*
✓ Modular design supports 130mm/135mm rear hub spacing common in modern road frames

Technical Specifications
– Chainring Sizes: 50T/34T (96mm BCD)
– Q-Factor: 145.5mm (standard road geometry)
– Compatibility: Works with all Campagnolo 12-speed groupsets & Shimano/SRAM road cassettes via spacing adapters
– Pedal Interface: Standard 9/16″ thread for universal pedal compatibility
