My point is, why Wal-Mart? These things are branded "Genesis" -- is that really Wal-Mart per se (like Kirkland=Costco?) or is it an actual (low-end) bike company that's innovating here?

If 32" does somehow take off (like 29'ers have), are we going to be stuck with decisions about standards that are already in place because of Wal-Mart?
