How is the quality of carbon wheelset from taiwan?
If it is an unbranded wheel from Taiwan, it is one of 2 things:


A quality wheel from a reputable brand being sold grey market. 


or


A quick and dirty design Made up so that somebody can make a fast buck on th Internet. 


Given the quality of the hubs and spokes referenced, in this case, it is the second option. 

I wouldn't buy those wheels. You will likely regret the purchase.
