HED H3 Deep FR Clincher Wheels $0.00
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 Wheels. 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 Wheels are a necessity for anyone looking to beat the wind, and not get blown around by it.
The H3D FR Clincher Wheels are 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 Clinchers utilize 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. The carbon layup, resins, and fiber orientations of the H3D are at their most advanced stages to date. When coupled with wider-is-better C2 technology, the result is a startling amount of lateral and torsional rigidity. To ice the cake, HED has also developed a 'secret weapon' it calls Stability Control Technology that effectively tames crosswind at any angle to the wheel. SCT is so secret that HED will not detail the process publicly, but the performance value is instantly recognizable upon usage.
Unparalleled quality control, aerodynamic design, and rim shape innovation set the H3 Deep FR Clincher Wheels apart from the pack. Decades of H3 podium finishes have reinforced that HED is better following the beat of its own drum, and that eventually, all others will follow.
The H3 Deep Clincher Wheels includes a titanium skewer and ratchet ring. The rear wheel is available to fit Campagnolo or Shimano/SRAM cassettes. Note that the maximum recommended user weight is 250lbs.
