    I have over 5,000 miles on this hub on my commuter/dirt road bike and it works. It may be a little less efficient and have marginally more drag than the Son Deluxe I have on my road bike but that difference lost when riding my heavier commuting bike. Most of the miles have been on potholed city streets with the rest (less than 500 miles) on dirt roads and rocky trails. I tested these out well and they have worked out well for me. And I'm expecting that it has a lot of life left in it.
