There's no reason for anyone to make 31.8 clamps for most levers. While the bar is nominally 31.8mm, that's only in the stem clamp area, and it will step down to the standard 23.8mm (15/16") OD for the working length.

You might conceivably need 31.8 clamps for anything clamped immediately on either side of the stem, like computers, but brake levers aren't mounted there.

Of course, some interrupter levers may need the larger clamp if the bar doesn't step down close to the stem.
