Ideal for flat stages or time trials, the DURA-ACE C60 focuses on aerodynamic efficiency and lateral stiffness. The new hub, stiffer spokes, and deep-section rims, thanks to their special construction, allow the rider to apply more pressure to the road during turns and ensure that every bit of power is converted into forward motion. Like the entire DURA-ACE wheel series, the new C60 has been completely redesigned from the ground up. Unlike the C36 and C50, the C60 series features a unique design of the front wheel hub and utilizes the OPTBAL 2:1 spoke pattern to enhance lateral stiffness. The C60 wheels also use stiffer spokes with a thickness of 1.8 mm instead of 1.5 mm.
