The Thirty-Eight wheel set is versatility at its best. Its shallow depth is an intimidating weapon for all road racers. The Thirty-Eights are deep enough to fly through long flat stretches with little resistance and able to tackle mountainous climbs with ease.

This wheel set was designed specifically for a road racer. They are fast, aerodynamic, and very agile in even the most adverse conditions. Proven to hold those fast 90 degree crit turns, they love to run. The carbon unidirectional finish provides a stronger rim side wall and a more stable braking surface. Built with the new iRT road hubs, they are lighter, stiffer, and faster than their predecessor. 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 for a stealth and intelligent machine.
