Deeper is better. Right Maybe if you love Chicago style pizza. When it comes to choosing race wheels, deep rims often bring with them instability problems caused by crosswinds. And even though you may feel fast, every millimeter of side-to side movement adds seconds to your time. To help counteract this, Steve Hed and his engineers created a deep-section wheel that not only improves stability, it also performs as a box-section wheel would in a crosswind -- in other words, the side to side shimmying is reduced. The HED Stinger 9 FR Carbon Tubular Wheelset is a result of these efforts. Stability Control Technology is a hallmark of HED's wheels. It is used to smooth airflow as it flows across the rim. This means that despite the larger surface area of the 90mm-deep rim, the wheel continues to hold its line in a crosswind because air is flowing smoothly over it, not buffeting against it. The nice thing is that even with this shaping, the wheel is no more visible to the wind than it used to be, so it offers a handling improvement with no aerodynamic cost.With the shape of the Stinger 9 dialed in, HED engineers shifted their focus to on the type of carbon used to make the rim, as well as the orientation of the fibers. Using three different types of carbon fiber and a unique layup schedule, HED made the Stinger 9 -- 15% stiffer laterally and 10% more impact-resistant, while at the same time making the rim 25 grams lighter.As with all HED C2s, this carbon-fiber rim is 28mm 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. It also maximizes the efficiency of tires by providing better support and a better-shaped contact patch for the tire. Because of the width, you'll minimize rolling resistance and maximize aerodynamics by using 22-23mm wide tires. 19-21mm tires wo...
