Vittoria Fraxion Road Wheelset. Vittoria enjoys a lengthy and storied position as a purveyor of professional level road tires, and now they've entered the world of road wheels with typical Italian flair and craftsmanship. The Fraxion road wheelset is Vittoria's top of the line clincher option, highlighted by its carbon fiberalloy hybrid rim. It's truly the best of both worlds as carbon fiber delivers stiffness, lightweight, and strength as only that compound can while the alloy braking surface delivers reliable stopping power in all conditions. The medium depth rims 40mm front and 50mm rear are perfect all arounders that deliver an aerodynamic advantage while ensuring great handling when crosswinds kick up. Vittoria's own Aero Lite stainless steel spokes further increase aerodynamics and Vittoria's own alloy hubs sport sealed bearings for low rolling resistance and low maintenance.
