your experiences please njee ?
My own King hubs required regular (often mid-ride) fettling to keep them tight, I had a bearing seize, combined with a not-particularly stunning weight, a hefty price tag and tonnes of bearing drag, I just don't think they're a great product. I know a lot of people get on with them fine, but not me. That's not to mention the expensive tool kit required to properly service them, which is reasonably fiddly, parts are extortionately expensive, adjustment of rear hub is fiddly and pointless, what do you achieve by having adjustable cartridge bearing hubs anyway? Hope, Tune, DT etc all manage without, and I'd sooner have any of their hubs.
DT hubs are far superior IMO, although admittedly they don't come in the tarty colours.
Anyway, this was about a fantasy wheelset, so I'll stick with the Tune hubs, although the exact details of the Dezibel rear hub remain to be seen, I assume it's got a carbon axle and as such is not user serviceable, which would stop me buying one. It does however, weigh half what a Chris King rear hub does.
AND… I call a service every 3 months reasonably high maintanence. The 240s on my road bike get a look once a year if they're lucky, those on my MTB are still totally smooth after a years heavy use and absolutely zero attention.
