While someone probably uses the same setup, I doubt that information is common. Litespeed is your best information source. 7x7, 7x9 and 7x10 are the three normal sizes. Litespeed could have easily had the clamps made for them without using off-the-shelf parts, with no aftermarket alternatives. So I wouldn't buy these without finding the parts, first.

The Enve clamps don't work like these do. But they could conceivably be made to work if the inner diameter is the same.
