I purchased this wheelset in mid October 2013. There has been no power hose cleaning, or non power hose cleaning for that matter, just bucket and brush, and it has been stored clean for about a month of no riding while I've been playing with another bike.
I went to it yesterday and the front wheel wouldn't go round.
One sealed bearing was pristine inside but totally devoid of any grease, the other sealed bearing was rust central. I tried to rescue them but although I did free up the wheel there was play in it, so I've banged the bearings out and ordered new.
I reckon that the wheel had done about 500 miles.
