These generic wheels generally do not have actual aero work done and very few will even show that they did CFD. This might seem marginal, but the even for optimized wheels the aero difference between a 40mm deep wheel and a 80mm one is like <10w at TT speeds. Poor design can easily erase gains that small. A lot of the aero charts also weigh high yaw angles more, overstating their benefits. IMO, there is very little point to buying aero wheels and frames that were not developed with aero in mind. That said, Far Sports is one of the more reputable carbon rim makers that sell DTC. My experience is a few years old and outdated, but I would say Light Bicycle made better rims back then. I've heard good things but have yet to experience the quality of their complete wheels.
