I bought mine a couple years ago when I got the devine inspiration to build the 'ultimate bike' - and spared no expense, (except for the frame, which is iro) and the crank set - which has roadie spacing.
Anyways, I am very happy with it.. it didn't explode on me or anything. I really don't know what else to say about it. I guess the only thing that could conceivably go wrong with it would be if the bearings went bad, but they are still good, they still roll smoothly after two years of all weather riding. I did have to tighten the screws that hold the cog on once or twice since I've had it, but that's about it.
I give it both thumbs up.
