Profile Design combed through the details with the 38mm Twentyfour Full Carbon Wheel to develop innovative manufacturing procedures and techniques. Increased compaction and precise construction for a stiffer, stronger, and more impact resistant rim. Industry-leading high Tg resin rated to 220C and custom formulated brake pads result in 30% shorter braking distance than previous Profile carbon wheelsets. Features: - From the resin to the pre-preg carbon fiber, each material was individually engineered to make it the best. - TwentyFour Series wheels feature proprietary rim shapes developed using Computational Fluid Dynamics. - 24mm wide brake track. - Sapim CX-Ray bladed spokes. - Proprietary straight pull hub shell for minimal aero profile. Weight: 1465 grams/pair.
