I have a Lezyne Road Mini on my road bike. This is after ten years of using a Topeak Morph Mini. The Topeak was a little heavier, and at this point has been moved over to my hybrid bike.

They actually both are pretty good pumps. The Lezyne looks more at home on a road bike, and is lighter. The Topeak is a better design for ergonomics since you can press it against the ground. It even has a little fold-out foot rest, which is actually useless if you're wearing bike cleats. But even so, the design is great if you get a lot of flats. But the Topeak is kind of big, would never do in a pocket, and is a little too utilitarian looking for a svelte road bike.
