sub 1500g - light rims - no torroidal tech but at 32mm im not sure it matters. KT hubs roll fast and last and you get a tried and tested carbon rim manufacturer / warranty.
weight on the rim has to be the key issue vs any minor aero gains from different rim shape. I have found my assaults to be really good over the 2+ years i have had them. taken abuse and all weathers (too lazy to change them).
These are the wheels PX copied and sell for £150. Narrow v profile mean they're quite different to Flos/Zipps etc
