Campagnolo Record Crankset: Precision Engineering for Road Cyclists
Crafted for elite road performance, the Campagnolo Record 2×12-Speed Crankset combines cutting-edge materials with refined engineering to elevate your riding experience. Ideal for competitive cyclists and enthusiasts seeking seamless power transfer and durability in demanding conditions.
Key Innovations:
✅ Advanced Carbon Construction – Unidirectional carbon fiber crank arms reduce rotational weight by 15% compared to alloy competitors while maintaining torsional rigidity for explosive sprints or climbs.
✅ Asymmetric Chainring Geometry – Patented Contoured Pin outer chainring design enables 30% faster gear transitions than standard designs (lab tested), while the mirrored inner chainring teeth prevent chain rub on technical descents or steep gradients.
✅ Ultra-Torque Integration – Precision-machined steel spindle (16mm diameter) ensures 95% power retention efficiency vs standard hollow spindles, compatible with all Campagnolo electronic groupsets (sold separately).
