Hello - I have a Diamondback Kalamar LX bike and would like to get an extra set of stock factory wheels (not sure if I'm using the correct terminology here, I mean the rims, spokes and hub unit), but I can't seem to find where they are available. I checked the diamondback website, and looked in their calatogs. I also googled and had no luck. I have not checked with any retail stores yet, is that the only way to go? Thanks.
