I've got the ever-lurking Nashbar SS 29er. The wheels it comes with, as is well known, have bolt on axles. What are my options if I get a new wheel set for this bike? Can I just get a standard QR wheel set, as long as I keep the tensioner on the back? Would I need a new tensioner? An additional one?

What about the front wheel? My assumption is that QR would be fine on that because there ARE inset locations where the nuts tighten on the wheel, and the QR should fit in the same insets.

Is there anything I should be thinking about that isn't covered by the above questions? Sorry if anything here seems particularly noob, I just hate to spend money and get it completely wrong.
