The CB Carbon shorts are designed to offer lasting performance and comfort with features and fabrics that wont let you down half-way through. The ergonomic fit of the shorts is combined with the use of highly stretchable and compressive CB Carbon + LYCRA fabrics which results in increased blood flow, reduced muscle vibration and reduced fatigue. An Aero Laser band is used at the thigh for a smooth transition that improves aerodynamics and muscle support, and an ischial relief zone relieves pressure at the back of the leg.
