I hate to say it like this, but what am I looking at?
Do you have the original article, what is the difference between the best ranking and the worse ranking?
I would say thats part of the game however, you are paying half of the price of the marketed brand without exactly knowing. It could be a similar shape and be .01 watt slower or it could be 3 watt slower. The CN manufactured products at least show the dimensions of their rims and dont make any (true or false claims).
For all we know - they are the OEM manufacture of the western/marketed brand and they just ripped of the design.
If you are very curious about what would be the most aerodynamic wheel you should look at a 3-spoke wheel for aerodynamics and to save weight over a full disc (I kid). You however should check out the Syncros Capitals
The testing they perform claims all the other tested wheels are within 2-2.5W of each other but the Capital is 1.19W faster than the closest competitor and 3.73W faster than the slowest tested wheel (Zipp 454NSW). At the end of the day is $4100USD worth it to be 2-4w faster than other wheels and if you flip it is 2-4w worth $1-1.5k USD more over a CN wheel for a marketed wheel brand (If it even is that much aero savings)?
This may not be everyoneās delima (if resources are not limited) and I like to think a lot of people like to make the most logical choice (for their situation).
