See, this is the trouble i have been having looking for replacement wheels, all the specifics. Hear me out, but i dont think theses will work. First the 700x25 means 700c, 25mm wide right? I am shooting for about 20mm so that would be too wide. Then for the hub, I think that is a cassette hub and I need one for a 5 speed free wheel. If not for that, the price cant be beat, would have been a no brainer.
