I was looking around for new wheels and thoroughly confused about the common approach to freehubs. Do they usually come with the freehub or do I have to actually put that on? If they do come with it, why in the world do none of the listings actually say anything about sizes?
Specifically, I was looking at this http://www.nashbar.com/bikes/Product2_10053_10052_541505_-1">listing which shows one in the picture, but does not give any specs.
