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

Built for competitive cyclists and endurance riders seeking peak efficiency, this double-chainring crankset combines advanced carbon fiber technology with Campagnolo’s signature Ultra-Torque system. Ideal for 12-speed road bikes, it delivers responsive power transfer and durability across varied terrains—from criterium circuits to century rides.

Key Performance Features
– Ultra-Lightweight Carbon Construction: Direct-molded unidirectional carbon crank arms reduce rotational mass by 15% vs aluminum competitors (686g total vs ~800g class average)
– Stiffness-to-Weight Ratio: Patented asymmetrical chainring design (48/32T) maintains 95%+ stiffness index while enabling safe cross-chaining
– Wear-Resistant Components: Hard-anodized aluminum chainrings with nickel-plated finish extend lifespan by 200+ hours compared to standard coatings
– Modular Compatibility: Works with 130mm BCD frames AND modern 135/142mm disc road hubs (chainstay length >415mm)
