The Shimano Dura-Ace WH-R9170 C40 Tubular Disc Carbon Centerlock Wheels 700c offers top aerodynamics with 37 mm full carbon tubular rims and disc brake compatibility for access to high performance disc Center Lock braking systems. The Shimano E-Thru thru-axle system ensures maximum torsional stiffness, which benefits the speed-oriented design. The wheels also impress with their low weight, e.g. the freehub is made of super-light titanium. For a more balanced spoke tension, the OptBal pattern is used on the rear wheel, where 14 of the 21 spokes are on the right and 7 on the left. In the aluminium hubs, reliable, carefully sealed cone bearings ensure low-friction running.
