All my bikes have King isodisc hubs except the DH bike. Now I'm building up a tubeless wheelset for the DH bike and am trying to decide between Kings or Hadleys. I will probably use Mavic EM 823 rims / 20mm front / QR rear / 14g straight spokes / brass nips. Anyone using either combination or have input on Kings or Hadleys used for DH application? Thanks.
