This little military-looking semi-tactical all-metal mini pump fits into any bag or pocket, and does a remarkably decent job of inflating tires, even fat ones. Being “small,” it takes more strokes, but it’s convenient, indestructible, light, and in two to five minutes, you can fill a 32mm to 55mm tire up to pedaling pressure. 

Presta specific but includes a schrader to presta adapter.

One size, 4.2 ounces not counting the plastic holder if you carry it on the water bottle bosses instead of tucking it into a bag.
