This is a Criterion series Cannondale, has down tube shifters.
Size: center point of crank it is 22 1/2 inch to top bar, 24 inch to top of seat post.
There is a decal on the bottom seat stay tube indicating it is a Black Lightening. One cable hold down is loose on top bar, there are paint chips & scratches as it is a used bicycle but I can not find any dents in the Aluminium tubing.
Understand the stem, drop bars, seatpost, saddle, and wheels are not original Black Lighting parts, but this bicycle rides like the wind.

I have been riding a 2010 Jamis Venture Race 15-25 miles each day, and find I do not notice every match stick in the road as I did riding the Cannondale on the same daily early morning route...
