Every brand of disc wheels purports that its construction is the fastest on the market. And while we won't go so far as to pick a favorite, we will tell you that the HED Stinger Disc FR Tubular Road Wheel is among the fastest of the fast. It's faster than the HED Jet Disc by nine seconds in a 40k time trials. And while nine seconds may not seem much, the race against the clock often comes down to just a few seconds. The Stinger is faster than the Jet for two reasons. One is that the toroidal bulge is longer. The second is that the sides of the disc where the disc meet the tire are taller. Both these features help smooth out the air flow over the tire and wheel. The result is something stunning. The Stinger disc has -90g of drag when the yaw angle is 14-degrees. Negative 90g. At 14-degrees of yaw, a conventional spoked wheel has almost 220g of drag (a 310g shift in aerodynamic drag) and even the HED Jet Disc has 30g. Compared to a conventional spoked wheel, the Stinger saves you 28 watts. As with the Jet, the Stinger is built via a hybrid construction. The wheel begins with a 24-spoke HED Sonic hub, 24 14-gauge spokes, and a carbon-fiber 24-spoke C2 tubular rim. Once the wheel is built, two carbon fiber lenticular panels are fitted over the spoked structure. The toroidal bulges in the rim section flare out to 26mm at their widest. Once the construction is completed, you have one fast wheel that is not only extremely durable but very stiff in the lateral plane. This lateral stiffness adds to drivetrain efficiency, propelling you forward with very little energy loss. As with all HED's C2's, this carbon-fiber rim is 23mm wide. C2 stands for the two C's that the rim is designed to minimize, Cda, or aerodynamic resistance, and Crr, or rolling resistance. The width is designed to maximize the efficiency of air passing over the tire and rim by smoothing out the air flow as well as maximize the efficiency of tires by providing better support and a better-shaped contact...
