Topeak Road Morph G (
https://www.rei.com/product/648089/t...ump-with-gauge) is the model of which I own multiple instances. It's not quite a frame pump, since it doesn't fit into the frame with a pump peg, but it is mounted to the frame with (depending on model year) zip ties or a plastic mount. Good enough for touring, but it helps if you have young eyes to read the gauge.
