Campagnolo Record 11x Chainset 53/39T

The new Record crankset with integrated bottom bracket is the most technologically advanced version of the Ultra-Torque system. The oversize axle system with outer cups is combined with a carbon fibre structure which is completely hollow internally Not only is the main crank arm hollow, but also the small arms supporting the chainrings of the RH crank.

THE RECORD™ CRANKSET EXPLOITS UNIDIRECTIONAL AND MULTIDIRECTIONAL CARBON FIBRE STRUCTURED ACCORDING TO ULTRA-HOLLOW™ TECHNOLOGY WHICH ENVISAGES HOLLOW CRANKS AND SPOKES.

The use of USB™ (Ultra Smooth) Bearings ensures very low friction and enhanced performance. Anticorrosion treatment for the cups of the Ultra-Torque™ system.

We have redesigned the tooth profile to optimize 11-speed operation. Our studies led to the ESP (Enhanced Shifting Performance) ACTUATION SYSTEM™, specially developed to improve shifting timing. Thanks to the new gear design, there are now two diametrically opposed sectors specialized for upshifting, and two downshifting sectors, also diametrically opposed. This solution makes instantaneous shifting possible both up and down. The darker colour of the gears is the result of a new anodization system which confers greater resistance to wear and saline corrosion.
