The Campagnolo Chorus 11 Crankset has both rigidity and lightness, with the use of unidirectional and multidirectional carbon fiber. Ultra-Hollow Technology produces a hollow crank and spider arms for improved weight to stiffness ratio and the Ultra-Torque Axle technology provides a stiff and lightweight connection for efficient power transfer. Campagnolo's Extreme Performance Shifting System (XPSS) was specially developed to improve shift timing, and features a redesigned tooth profile to optimize their 11-speed operation. Thanks to the new chainring design, there are now eight sectors specialized for upshifting, and two diametrically opposed sectors for downshifting. This makes instantaneous and precise shifting possible both up and down.
