Thought Shimano was a good quality part until this hub. About 3500 miles on these hubs and looking at my forth freehub. First went from water intrusion, second got very loose after about 1000 miles. Third has been on 500 mile and is loose. I will nurse it for some more miles but I do long distance rides and don't want to be stranded if it should let go. I keep searching the web for a better quality replacement with no luck. Seems I will have to change the complete hub to get a better quality freehub.....
