You can certainly run those wheels SS, but you would be loosing all the design benefits of that wheel. Fulcrum 7s have a funky 2:1 lacing pattern to compensate for the dish (asymmetry) of the wheel. The asymmetry is there to allow a big fat multi-geared cassette to fit in there. A true SS wheel is undished (or barely dished), thus allowing for a symmetrical spoking pattern and equal tension on the left and right sides, which makes the wheel stronger, stiffer, structurally more stable, and more durable. True SS wheels are not very expensive, but even a relatively cheap one is going to function better as a SS wheel than a Fulcrum 7.
