Not yet, few more bits to go on the build I'm doing. But they inflated tubeless real easy, spoke tension seems good, only thing left to determine imo is the robustness of the hub internals, I've looked for koozer hubs failing but can't find much. The rims also seem 100% legit sun ringle Duroc 40s, measurements are spot on and the nipple holes are silver rimmed, those two rims alone are nearly the price of the wheelset where I'm from. I'm quietly optimistic.
