Model R and SR are dedicated to all those who look for a hybrid frame that can work with mechanical or electronic shifting. A composition of 3 materials, an expert blend of 3 fibers employed and carefully measured to obtain a precise goal. The aim was to increase stiffness without impairing comfort, to lighten whilst maintaining a unique stability. The composition is made up of 55% TI 800 fiber, 35% TI 1000, and 10% XN60. The Superking increases the STW (stiffness to weight) value by 25% compared to traditional competition racing bikes.
