I grew up with shrader style tire valves so when I got my Trek FX3 5 years ago, Presta valves took an adjustment period. I bought a $30 Serfa pump from the local store. For a long time, I thought it was my fault that my fingers were getting smacked when the pump head handle would snap back. And I didn't understand why it was so difficult to get the pump head to seat properly on the valve. After learning that I needed to replace bent valve cores, I decided it was time for a better pump.
I shopped around and picked this one. It's a major improvement. It's so much easier to screw on the chuck head, pump it to exactly the desired PSI and unscrew the chuck. Inflating tires is much easier and pain free.
I bought the Topeak JoeBlow Pro X Floor Pump as a replacement to a decade old floor pump. The Topeak JoeBlow Pro X Floor Pump is a superior floor pump that I would highly recommend. I really like that the pressure gauge is positioned higher up on the unit to clearly see the pressure read out. The stance of the base is solid and does not rock in any way, metal base is flat. I also like the fact that the extension tube can be used for short or long scenarios, I will often pump my tires up while my bike is still mounted on the hitch rack on the back of my vehicles. Lastly, the head unit that attaches to the bike tire valve is great. You press it on to and it secures and it holds and locks with no leakage.
I have a couple of things to share after using this pump 3-4 times a week for almost a year. The biggest learning I had was to pump a tire to pressure and then close the tank/chamber valve before disconnecting the pump head from the valve stem. The disconnect and sealing of the Presta valve is fairly instantaneous instead of leaking off. Plus, there is less pumping to get to pressure for the next tire. Topeak should add this to user instructions for less savvy people like me. I have left the reserve chamber at pressure for multiple days without significant leakage and dropping in pressure. Its pressure gauge is easy to read and its accuracy matches my Topeak expensive digital pressure gauge. The pump head also fits Shrader valves nicely and without having to disassemble and reassemble the pump head like some other pump heads. The build quality is excellent. I can't think of anything I would change on it. I hope it lasts as long as the 25 year old and still going Avenir pump I gave to my son.
I bought this pump for the larger gauge and assumed that it would be good quality. The pump is lightweight, compact, and pumps well. As a road bike rider, the larger, non-linear gauge is of limited value (except for the larger size) as the more detailed pressure reading stops after 30 psi. Regarding the head, I hate it. My other pump has a head where the lock lever is mounted to the side and works great. The way the Silca head is designed I find that I am always pinching my fingers when I snap the lever to release. Maybe it's just me, but I couldn't get use to it. Finally I broke down and bought the Silca Hiro V.2 side lever head. This combination works great, but the pump/Hiro head is way too much $$. I could only recommend buying the pump/Hiro head on sale which I did.
