  • Great pump
Color: Blue
Directions aren't the best (the direction of the valve grabber handle), but once my thick brain figured them out, it works like a champ, and I had zero issues mounting it. I don't come close to hitting it when riding so no worries there.

  • Can’t go wrong with Parktool
Color: Blue
Works well and is of good quality. This pump is a bit larger than the micro pump and is ideal for bigger tires, but it is still lightweight.

  • Best of the best
Color: Blue
Why did you pick this product vs others?: Probably the best miniature pump made

  • Not for > 60psi :(
Color: Blue
Given its compact size, I had hoped the PMP-4.2B mini pump would be more effective. However, I could rarely get the pressure past 60 psi without putting significant strain on the valve. It fell short in that regard, so I eventually switched to a flexible hose pump with a gauge (Voxom Floor Pump PU14 mini pump). ... show more

  • Size and efficiency
Color: Blue
Bought this after reading some product guides that recommended this as one of the most efficient pumps for its size. I concur that it is small, light and effective. The review (from Singletracks, maybe?) said it only took something like 3 pumps to go up one psi--I've found it to be more like 7 pumps in my 2.3 tires, but I'm happy with it. I specifically wanted a pump that didn't have a hose that threaded onto the valve stem, as these are notorious for removing the cores when you unscrew them (so frustrating). I can fit this pump in my USWE 3l pack if the bladder isn't full. I only take it on rides where I'll be out in the back country, and I still carry Co2 to seat the tire. ... show more

  • Came with a problem
Color: Blue
I purchased this pump as back up for C02 cartridges on my gravel bike. It arrived in non-working condition. I contacted Park Tool and they sent me another even though I purchased it from a third party. It works, although I have not, thankfully, had the occasion to use it on a ride. Park Tool is very good with customer service, which can make up for the high prices of their tools. ... show more

  • Good Volume, very lightweight
Color: Blue
If you’re a road biker you are probably going with a CO2 set up, but as a MTB I’ve found this hand pump to be life saver. There’s been multiple times on the trail I’ve run into someone with a flat and their CO2 was old and empty, or they didn’t have a presta valve. This pump connects easily to the frame or, like me, just toss it into your Osprey water pack. It weighs almost nothing, and it’s way better to have it and not need it, then need it and walk back the 8+ miles to the trail head. ... show more

  • It doesn't work
Color: Blue
It does not fill bike tires with air. Therefore it is totally useless.
