Campagnolo Record 12-Speed Crankset – Precision-Engineered for Road Performance

Crafted for competitive cyclists seeking lightweight durability, this double-chainring crankset combines aerodynamic carbon fiber arms with a robust steel spindle. The 52/36T asymmetrical chainrings deliver optimized gear ratios for mixed terrain riding, while proprietary Ultra-Torque technology ensures rock-solid power transfer across all cadence ranges.

Key Innovations
– Unidirectional carbon crank arms (170mm length) reduce rotational inertia by 15% vs aluminum competitors
– Contoured outer chainring pins enable near-silent 12-speed shifting under load
– Symmetrical inner chainring teeth design improves chain retention during steep descents
– Military-grade anodized aluminum chainrings withstand 40% more wear cycles than standard finishes
