Five-Eighty-Five Carbon Clincher
Add to Cart

For the triathletes! The Five-Eighty-Five wheel set is an aerodynamic partnership, coupling a 58mm deep front wheel with an 85mm deep rear wheel. By using a staggered wheel system, riders experience more responsive handling, with improved speed and agility and less drag. Long favored by triathletes and time trial racers, the Five-Eighty-Five set shows a true meaning of teamwork. With wheels accounting for 7%-11% of the total aerodynamics of a bicycle, decreased drag can translate into quite a bit of time for both triathletes and time trialists. Built with iRT road hubs, they are lighter, stiffer, faster and have a near instantaneous engagement. The carbon unidirectional finish provides a stronger rim side wall and a more stable braking surface. Made with high quality bladed spokes and high strength 7000 series alloy nipples, this wheel-set will last for years to come. Upgrade to a PowerTap hub, and a stealth intelligent machine is born.
