Campagnolo Chorus 2010 Carbon Ultra Torque Chainset 170mm 39/53
The 11- speed Chorus? crankset has been treated by the special 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. We have redesigned the tooth profile to optimize 11-speed operation. Our studies led to the ESP (Enhanced Shifting Performance 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 specia system which confers greater resistance to wear and saline corrosion ?
