le manque de détail fait que cette pompe ne peut se monter sur un cadre prevu pour une pompe de 50mm au repos, deplus la qualité est vraiment pas terrible

Way too many times I've been standing by the road watching other riders use up their CO2 and still be left with a flat tire. Usually this is due to incompetence. There are simple, specific procedures required for changing a flat; if you don't follow them you will not have a functional bike.Same with any kind of pump, but especially this one. It's very light weight, and it requires a firm, careful grip to hold steady while you are pumping. Not to mention you should know how to diagnose and repair a flat tire in the first place.To the other reviewers who complained: it's not the pump's fault. I've used this pump countless times to successfully air up road bike tires to 90 psi or more.WARNING: if you are the mechanically incompetent type, or you only ride with roadies who have never even seen a frame pump, you should not buy this. Instead just carry a phone and call for a ride to the nearest bike shop.

Good quality and a good price. Looks good on a vintage bicycle - although is vulnerable to theft as they always were, which OSS probably why mine was misting in the first place.

Zügige Lieferung. Preis-/Leistung gehen voll in Ordnung. Im Test keine Probleme.

Excelente relacion calidad-precio, por un presupuesto ajustado (3,5eur) puedes hinchar una rueda de bicicleta BTT a una presion considerable. Hay que hacer un poco de esfuerzo para llegar a dar bastante presion, pero cumple sin problemas. Se nota que es marca Zefal, personalmente mucho mejor que cualquier bomba de pie fabricada en china y de mala calidadEn contra, el tamaño (se puede llevar en la bici comprando unos acoples( pero para tenerla en casa para un apuro es mas que suficiente
