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. Anti corrosion 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.
Full-carbon unidirectional-multidirectional cranks - hollow cranks (Ultra-Hollow Structure) - light alloy fixing bolts and nuts - light alloy chainrings with ESP Actuation System (Enhanced Shifting Performance) - chainrings with hard anodization treatment - 8 pins on the large chainring - USB bearings (Ultra Smooth Bearings) - integrated ULTRATORQUE semi-axles - requires ULTRA-TORQUE BB cups.
