Crankbrothers Gem Hand Pump

Had too many problems with another manufacturer's pump. This is well built, easy to use, and works great.

Great little trail pump. has presta and schrader capabilities and it has 2 settings for pressure hi and low. Honestly no complaints at all.

Seems good so far. Haven’t encountered a reason to use it when out and about yet. One thing that was significant to me is: the lever is in the shipped position when being placed on the valve and then gets pulled up to secure it and commence pumping. Seems backwards to other pumps I’ve used, but obviously very important.

Perfect & fit, form, & function is all there! Some have commented on it being thicker than some but I love it’s overall short and stoutness (it’s really not thick either maybe 1” round) & to the people who say it doesn’t work on Presta valves, should figure out how it works before commenting (effects sales) but YES IT DOES you unscrew the lid cap & turn the rubber piece inside around & re thread cap back on & whallllla , universal lol! But yeah love it on my aggressor pro paired with my blue crankbros stamp 1’s!! MY ONE complaint is that the head swivels freely (but not much & don’t notice when riding) so my hack with be a 1/4” round black magnet to the body for the latch to stick too to keep it in place (has a metal bar around valve switch) but really hasn’t/doesn’t bother me much! Solid Pump!

I carry this pump in my pack on every ride. Very compact yet very effective. I've used it on the trail with and without tubes. Those who have borrowed it have all been impressed. Best trail pump I've ever owned.

I have been using CO2 cartridges for several years and like those pretty good. However, the past several months I have in plagued with flats due to the goathead burrs in our area. So...the reset process can get rather costly with the CO2. I have been carrying this pump, which fits into a parts bottle or canister of some kind, which I carry spare tubes, lever and other emergency fix items. I like this a lot and sure suggest anyone try it. Compact, but not too small to function effectively and sure works great overall.

This is great! Another wonderful crank brothers tool I own. Althiugh slightly bulky, that might be it's only downside. It has two setting for lower and higher pressures and fills even fat bike tires pretty quick, especially for a hand pump.

The pump design lets in a LOT of dust and or water. Would be best suited on a road bike. The pump head doesn't lock into place like other pumps I've had so it can rattle around. Wouldn't recommend for off road use

Habe mir die Pumpe für unterwegs gekauft. Sie passt super in selbst die kleinste Ecke des bike Rucksacks. Durch ihre Volumen Verstellung ist der Reifen im nu aufgepumpt. Würde ich sofort wieder kaufen

Perfecta para bicicletas que usen llantas entre 30-110 psi, más se volvería muy difícil bombear. Saca de cualquier apuro en caso de pinchar, ya me ha salvado un par de veces.

Einwandfreies Produkt. Bin sehr zufrieden. Im Vergleich mit anderen Luftpumpen dieser Größe klar vorne mit dabei.

Gran producto de buena calidad, muy recomendable, esta muy bien dimensionado para ingresar en bolsas de herramientas, porta bidon y botes de herramientas.

Es myy incomodo y poco funcional
