H3 Deep FR Rear

If we're honest with ourselves, it's easy to admit that disc wheels aren't always a blast on the open road, and for some disciplines of cycling, they're not even allowed. That's why HED produced the H3 Deep Clincher Rear Wheel. The H3D is the fastest non-disc HED wheel to date and it excels by leaps and bounds over its deep-section competition. The H3D FR Clincher Rear Wheel is a necessity for anyone looking to beat the wind, and not get blown around by it.The H3D FR Clincher Rear Wheel is an amalgamation of the Jet 9 Aero rim and the standard H3 FR. The H3D gives you all of the advantage of the H3 FR design and then some. For one, the aero section of the H3D FR rim is molded from a stiffer and lighter Uni fabric. There are numerous aerodynamic advantages from the 90mm rim depth, as well. As a rear wheel, the H3D is faster than any other non-disc HED wheel. So, if you specialize in a discipline that prohibits disc wheels, like triathlons, you stand to gain a monumental advantage. It has been found that the H3D works to correct yaw wind angles at the rear of the bike, giving it a distinct advantage over some discs. While other companies are just now starting to improve upon the carbon clincher wheel, HED has been fine-tuning perfection for decades. Just as the favorite child gets an extra scoop of ice cream, the H3D FR clincher has enjoyed numerous technological innovations and improvements to further cement its position at the top of the heap. To begin with, the H3 Deep is extremely aerodynamic. The H3 Deep FR Clincher Rear Wheel utilizes three main components to achieve its low drag ratios: a 90mm deep rim section, airfoil section spokes, and the smooth connection points where the two join. This design has eliminated drag resistance from every angle of the wheel. The deep rim section is designed to minimize drag at shallow yaw angles, and, past 15 degrees, the shape of the airfoil spokes allow airflow passage to keep the wheel from stalling.The H3D's protection from extreme wind angles is not limited to aerodynamic measures. HED pioneered the wide rim design that dominates today's carbon wheels with what it dubbed C2 Technology. C2 Technology's goal is to reduce the occurrence of the two main drag variables: aerodynamic resistance and rolling resistance. In 2006, HED set out to correct the problems associated with fitting tires into narrower rims, problems like higher required pressure, increased rolling resistance, decreased handling, and increased drag. HED found that by making the rim edge wider, a 23mm tire would flow exceptionally well into the rim shape, and thus create a flush aerodynamic profile for optimal airflow. So C2 technology doesn't only address aerodynamics; it also reduces mechanical drag by increasing the contact patch with the road, further improving the distribution of load and lowering rolling resistance.The HED H3 Deep FR Clincher rear wheel focuses on rigidity and stability.
