I rode a set just like them for two seasons prob around 2500 miles with out issues outside of a couple of truings. Got a little worried about long term durability on some of the longer rides I have been doing this year and jumped up to 32 Spoke Open Pro's. I'm very easy on equipment though, I prefer to spin than mash and I climb really smoothly. I'm also pretty light on the wheels going across rough stuff and always keep my tires aired up.
