The HED H3D FR Carbon Tubular Road Wheel has only been in production since 2007, yet it lays claim to victories at the Tour, the Giro, and Beijing. Even the prototypes, being tested as early as 2005, were turning heads in timetrials. The H3D not only looks cool, it's also fast and you'll be faster for riding it.
The H3D Tubular Wheel is an amalgamation of the Jet 9 Aero rim and the standard H3 FR, but 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 the stiffer and lighter Uni fabric. There are numerous aerodynamic advantages from the 90mm rim depth, as well. As a front wheel, the H3D is faster than the H3 at yaw angles up to 10 degrees. This benefits the beast who is continually riding above 25mph where yaw angles tend to be consistently lower than 10 degrees. However, you will find the inverse to be true for riding under 25mph. This leads to the question of if you'd benefit more from the H3 Deep or the H3. The H3D is HED's fastest non-disc wheel, so anyone specializing in a discipline that prohibits disc wheels stands to gain a monumental advantage. If your discipline finds your average speed to be below 25mph, the H3 will be your choice of front wheels with the H3D being better suited as a rear.
The H3 Deep is extremely aerodynamic. It 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 heavily reduced drag resistance from every angle of the wheel. Coming in at only 19mm wide, the deep, V-shaped 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 HED H3 Deep Tubular wheel also focuses on rigidity and stability. The carbon layup, resins, and fiber orientations of the H3D are at their most advanced stages to date. The wheel features a startling amount of lateral and torsional rigidity. To ice the cake, HED has also developed a 'secret weapon' that it calls Stability Control Technology (SCT) to effectively tame 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 Tubular Front Wheel 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 H3D FR Carbon Tubular Road Wheel includes a titanium skewer and ratchet ring. It's available individually as a either front or rear with SRAM/Shimano or Campagnolo compatibility. Please note that the maximum recommended user weight is 250lbs.
