Yes, inadvertantly; due to the R20's BB issue I have had to commute with the Swift, and it turned out to be the wettest 3 weeks in years. I literally washed the bike twice a day! I have done somewhere between 1-2000km on the hubs, and in just 2 weeks completely wore out the brand new brake pads!
So the hubs have seen commuting duty which is heavy duty work - extra 10kg of luggage, bumpy bike track, wet, wet weather, mud, grime, grit, frequent washing, you name it. The wheels are still as true as when I built them and the bearings feel smooth. the freewheel is much louder, though. Better check it tonight.
I must say I am relieved since I have read some bad reviews about the AC bearings.
That's good news. It sounds like they've addressed the problems with the new hubs. At a minimum, the bearings are now easy to find. My rear dropout is 135mm, so I was tempted to go with their mountain hub, but got cold feet since I tour in places that would not have parts available.
