overview

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 special 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 special anodization system which confers greater resistance to wear and saline corrosion.
