When seconds matter and the racecourse is as flat as a pancake we ride with the Shimano Ultegra WH-R8170 C60 Carbon Road Wheelset. This aerodynamic wheelset is made to slice through the wind and get us from a to b, or just around our local loops, faster than ever. The carbon rim construction means better stiffness without shedding grams while the deep rim profile carries speed easier with less resistance.
