Noah Singerwrote a review of DT Swiss 240S 12x142mm 6-Bolt Hub on April 23, 2015
Familiarity: I've put it through the wringer
I ride a set of Enve M60's with DT 240 hubs. People often ask me if they should get these hubs or Chris King on their next bike. My response -- Basically, you get Chris King if you want to prance around and say you have a quality hub, then at night you don?t mind working on it. You get DT Swiss if you actually want a quality hub and at night you?d rather ride then just drink a few beers after.
I've had both and put a lot of miles on each. King is good, but has a break-in period, that is longer than a few rides and requires constant adjustment to keep them running like a tight ship. As far as DT, I've never touched them.
