I did the switch from 1500grams DT swiss road wheelset, to a similar weight DT hub + asian carbon rim.
It's not only the weight, you upgrade to a material that is better suited for a wheel that doesnt use rim brakes, ride quality is better and you get the option to go as wide or deep as you want without a noticeable weight penalty. It s a good opportunity for 23+ internal width.
Asian hubs are good these says, i ride some serenade and elitewheels ratchet hubs and feel similar to DT, they are smooth and reliable, i have been riding the elites for 3-4 years, and serenade wheels around 7k km.
