I'm realizing that good pricing can be had on some suitable wheels due to the 29er craze. While the frame is spaced to 130mm, 135mm isn't much more and with a spacer removed and a slight pry I should be able to fit these in the frame. As it is, it's pretty easy to fit the 135mm rear wheel from my mountain bike in there. The rims will be slightly wide for 28mm tires but should be fine.
