These hubs are absolutely beautiful in every way! I have the luxury of having a toolset at my disposal to rebuild them when I want, but have to say that every time I rip them down they are totally clean inside. This is absolutely not the case with all of the other hubs I've rebuild over my life. They run smooth with a little more drag than some others, but I'm not in the Olympics and don't get a new pair of wheels every race. They are simply SOLID and THE hubs I'd choose over again. I've seen many new to the game shiny flashy hubs that pretend they are like Chris Kings blow up in no time flat and all I have to say is "Save your money and get a King!"
