Hed?
Some of the Hed ones look pretty decent in their ads in triathlon 220, and price / weightwise they’re not looking too bad. Plus they’re the daddy’s of aerowheels from back in the day, so I expect them to know their stuff.
Personally, I have bontrager aeolus 5.0’s which are light, stiff, aero and have DT hubs so they work a treat – they’re a revelation up the climbs and even nicer for general riding.
Winter now though, so they’re all boxed up until next year…
