I imagine your Skyteam forks are pretty spindly so these clamps may well be too large. The manufacturer does say that they'll make up custom sizes to order but I expect you'd pay for the privilege, (which might be a bit extravagant for something you'll probably only use once!).
Alternatively, I have seen homemade clamps made from wood, which you could try. A old cut up inner tube would provide extra protection.
