I rode one commuting (and still am) 32 miles rt mix of road, trail crused stone w/lots of pot holes and city streets since last October. It was great in the winter not having to claen the accumulated grit out of a freewheel. The wet gunk that accumlated on the chain was substantial. The hub has perfomed great w/ no maintinece except adjusting the shifter cable and cleaning the cog. Shifts well under load and I am happy with it. BTW, I had a bike w/ Nexus 7 and this hub (mine is premium red band) has less drag and is quieter. Hope that helps.
