Want to know what it feels like to ride on top of a missile? The Fifty wheel set provides just that. Its intricate construction makes it versatile enough for comfortable daily use, as well as provides speed and agility during your most competitive situations. The smooth airflow over the surface of these wheels is an addicting ride, for roadies and triathletes alike. The wheel is designed to allow for smooth airflow over the surface of the wheel, while being narrow enough to not get caught up in a cross wind. The carbon unidirectional finish provides a stronger rim side wall and a more stable braking surface. Built with the iRT road hubs, they are lighter, stiffer, faster and have a near instantaneous engagement. 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.
