the wheelset you are buying sounds really cheap which means it probably has suzue jr. or basic hubs. these are total monkey poo, but if you are still testing the waters on this fixed thing they may be good enough for you. just 1) make sure whoever puts on your cog puts it on tight 2) DO NOT under any circumstances try to skid! you will rip the paper thin cog threads right off that hub! i have done it, it's not hard.
if you are more serious, but still thrifty, you can score a formula wheelset easily off of ebay which will be a much much greater value than a suzue jr. one.
