Definitely "modern" frames with vintage parts. The cable guides for integrated brake/shift levers on the headtube give it away. The seat lug should let some of the internet sleuths identify the frame. It has a unique pinch bolt tightened from the rear, which I don't recall seeing often. The fork and BB lugs look inexpensive, but it's tough to tell with the low-res pics, so I'm too interested to know what the frames might be.
