CrankbrothersGem Bike Hand Pump - Short/Long Dual Piston Pump, Presta/Schrader, High Volume and High Pressure Hand Pump

Una pompa così ti può risolvere un bel problema se devi rigonfiare ruote tubeless antiforo.......comoda, piccola ma efficace.....attenzione, per utilizzare valvole presta l'ugello va svitato, la guarnizione capovolta e riavvitato.....come indicato nel disegno della confezione...che avevo gettato...per fortuna c'è YOUTUBE!!!

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

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

Thought I lost my pump. Just found it. Meanwhile I purchased a second one to replace it since I know it works well, and bought one for my special lady friend too. My first one had gotten a bit gritty and seemed to stop working. Mounted on my mountain bike or commuter downtube it had picked up a lot of crud. No worries, it's serviceable. I disassembled it and found all sorts of slimy gritty junk inside. I washed the bits in some warm soapy water, rinsed them well, and let dry. Once dry, I put a very light oil (not chain oil, not WD-40) on the seals and put it back together. Like new!The two stages is perfect for higher volume, lower pressure MTB tires, but will get you up there for your road bike applications too. The size is pretty good, not too tiny that you can hardly handle it, but not absurdly large either. They make a shorter version also.

Perfect
