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.
