HED Jet Disc Black
Starting from our revolutionary 25mm-wide Jet Plus aluminum rim, we spent hundreds of hours testing and refining a new braking surface, called Turbine Braking Technology. With special machining and anodizing, the result a super clean all-black appearance and outstanding brake performance. Additionally, the consistency of stopping distances has improved by nearly a factor of five. That’s not a typo. Our all-black alloy rim and carbon cap give you all of the cool factor, and none of the safety compromises of rim brake carbon clinchers. No melted rims. No tire and tube failures. Only True Speed.
The Jet 4 Black is similar to the Jet 4 Plus in that, it is an all-around great choice for road racing, or anyone looking to thread the needle of light weight and aerodynamic performance. With a 46mm depth (and massive 25mm width), this rim results in lower side force than its deeper cousins, with aerodynamic performance that would make competitors’ 80mm rims jealous.
