I've got seven sets of King hubs on my many bikes. I like them because they are well made, modular design (King sells spare parts directly to the consumer...which is a big time savings), and King stands by their products. They have upgraded a couple of my original classics with new axles due to improvements at no cost to me. I think the bearings are far better then say the cheap cartridge bearings in Mavic hubs. Although, they do have some drag and new hubs take a while to break in but if the instruction in the manual are followed all's good. To me King is worth the extra money. Although, I'm open to trying other hubs such as, Industry Nine, Hope, or Hadely
