Campagnolo Chorus 11s Crankset has been embellished by the new surface anodization treatment which renders the Chainrings more resistant to wear and to corrosion. The asymmetrical toothing of the innermost Chainring and the eight pins on the outside render shifting immediate . Campagnolo has redesigned the tooth profile to optimize 11 speed operations. Thanks to the new gear design, there are now two diametrically opposed sectors specialized for up shifting, and two downshifting sectors, also diametrically opposed. This solution makes instantaneous shifting possible both up and down. The darker color of the gears is the result of a new anodization system which confers greater resistance to wear and saline corrosion. Unidirectional and multidirectional carbon fiber. Features:

• Sectors with special ESPTM profile on the outermost Chainring
• Long life anodization treatment
• Light alloy screws
• Ultra-Torque bottom bracket
• Weight 684g
