7005 mass-start track frame for bay area rider

This one is tiny 43 cm. seat tube, 48.7 top tube. It will have overlap but that is what you expect on a really small track frame. The frame weight is 3 lb. 3 oz. -could have made it lighter but I want it to last as there are a lot of kids in this family and there's a good chance after mom is done track racing one of the kids will get the bug.
