Pompa da usare in caso d'emergenza, direi ottima rispetto alla precedente. Utile il doppio stadio: alta pressione o alta portata. Per gomme MTB 29x2.2 bisogna avere un po' di pazienza, ma, se avete le gomme tubeless con lattice e avete perso pressione questa è una soluzione che funziona sempre.

I ride many thousands of miles a year and have used many pumps and had lots of flats. This pump is great for many reasons. First, it actually effectively pumps the tire with air. The two speed pumping function is really useful to get the tire up to high pressure without the exhausting effort needed in the 50 to 80 psi range that other pumps typically entail. Second, and very important, this pump style has the latch that grabs the valve, rather than the flexible hose that screws on. I found, again and again, that those screw-on hoses more often than not unscrew the valve core when removing, leaving you with a totally flat tire. Several times I have been stranded, not able to get the valve core tight enough by hand to withstand the hose unscrewing the valve. I remember being by the side of a highway on a 100 degree day, constantly re-inflating my tire and very carefully trying to unscrew the hose without usncrewing the valve core. It was like Sisyphus rolling the rock up the hill in Hades. Third, it is very light and compact. They say 117 grams which is incredibly light. Not as light as my stylish 85 gram pump which looks really good, but does not pump to more than 10 psi. I am happy to carry the extra 30 grams to have a pump that actually works.

excellent product, I recommend it

Es una bomba muy chica, se utiliza sin dificultad y cabe perfectamente en las bolsas q se colocan debajo del sillin de tamaño mediano. Los materiales son de aluminio y si pesa un poquito.

Very good product

My second Crank Bro’s after a very long and rather strenuous test of my first Crank Bro’s hand pump (which I lost after ten years of use - would have kept going). The presta/shrader dual use design has improved a good bit on this newer model. As with the first, If you ride the rugged trails, I recommend keeping the pump secure in a pack, not with the included frame mount. Nothing wrong with the frame mount for a less moderately aggressive ride, though. Very light and short pump that nonetheless feels very durable. The hand pumps without a hose (like this one) sacrifice ease of inflation for compactness, but I’m still able to pump up to 50 psi, and much prefer this short pump over other longer models since I don’t often get flats anyway.
