Campagnolo Chorus Ultra Torque Carbon Road Bike Crankset

The Campagnolo Chorus Ultra Torque Carbon Road Bike Crankset was designed for optimal performance. Campmagnolo's 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. Featuring full-carbon unidirectional-multidirectional cranks - 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 - integrated ULTRA-TORQUE semi-axles - requires ULTRA-TORQUE BB cups, 690g.
