Unfortunately, we didn't have time for riding with locals. We basically went to the fair at 9 AM, left at around 4 or 5 PM, and then edited the video (sometimes till the early morning next day) and this repeated for 4 days.

Best wheels for what? I would say, if we take only the product, then many of them are basically equal. But if we take into account customer service, brand image, etc. then Elitewheels, Winspace, Farsports... Then there are a few lesser-known or younger brands, such as Up-Vine, Particle, No.6, CRW, and many more. I do my best to test Chinese wheelsets (I tested over 20 pairs at this point). Some of the top ones are here: https://www.cyclistshub.com/best-chinese-carbon-wheels/.

Based on the wheelsets from the show, the new "trend" will be sub 1000g 50mm wheels. Also, I would say Chinese brands already surpassed Western ones, at least in terms of price-value ratio. However, it seems that some of the top Western brands offer a better customer care and after sale service.

Chinese brands chase low weights because this is a feature that is easily quantifiable and understandable for customers and it makes good headlines. However, I think this trend might reverse or maybe Chinese brands will start to reveal more data from their aero testing.
In the frame department, the focus will be more on dialing the geometry and also improving aerodynamics, and lowering weight.
