From completely deflated, each pump for the Presta valve tubes that go inside my tires was a 1 to 10 pounds ratio at first. Some of you road bike snobs or Freds can't comprehend this type of witch craft.but it actually works. I bought this pump in part because the upper range is advertised to be 100 pounds and a combination of the stiff frame I have and where I typically ride makes me usually keep my tire pressure in this application between 60 and 80 pounds. To be fair, if the actual pressure is 26 vs 28 vs 30, it's not so incredibly critical.Ģ) I have a cyclocross bike that currently runs a 700x28 Armadillo Elite.

In such a low range, within about 2 - 3 pumps, I was in the recommended range, but because of how the gauge on the pump exceeds the actual air pressure at first (kind of like when you first step on a scale, your initial downward force is over reported because of the physical motion of stepping), I had to slowly through trial and error tinker with how best to get the right amount of air in the tires by releasing the pump head valve, then re-engaging it until I was in the right range. I'll give some examples:ġ) On my motorcycles which take a "normal" Schrader valve, the recommended tire pressure ranges between, say, 28 and 34. Kind of like how an average student might show promise in the first few weeks of class, then around the final 1/3 of the course, really fizzles out. Then, the usefulness really tapers off and as you get into the higher end of the useful range, it becomes increasingly more difficult to use. I think because of the design and the barrel size/shape, you get a lot of bang for the buck maybe 5-10 psi per downward pump. Why the "+?" Well, it does one thing really well. I'd describe this pump as being "adequate." Like if it was a student taking a general intro class that all students have to take, it'd be in solid C/C+ range. The sleek and compact design of this pump does not compromise on functionality as it still ensures your needs are met without costing you energy or time from your cycling experience.I picked one off Amazon Warehouse that was in "like new" condition for 15$ and tax, so I can't really complain about the price. The pump features a lightweight design of only 2.15 pounds making it easy to pack and necessary addition to your gear.
