To realize the aerodynamic wheelset, it is not to use aluminum to complete the rim material, because the key to the aerodynamic wheelset is a deeper rim. If aluminum is used as the rim material, the weight is unimaginable, and it is precise because of the development of carbon fiber technology in recent years that aerodynamic wheels can be realized. Low-weight, high-strength carbon fiber material makes aero wheels possible. GCN has also made a special experiment for this. Under the same power output (200w), under the same conditions (frame, rider, temperature, etc.), the higher the frame height, the better the aerodynamic effect, and the faster the speed.
