Blackburn Mammoth Flip Bike Mini-Pump

It was a bit more expensive than others, but it fits in my trunk bag nicely without having to be stuffed in diagonally. Really well made, high quality construction. I was impressed when I got to examine it. I would buy it again.

The lever and fitting that attach the pump head to a presta valve seems to be loose and sensitive to the slightest motion. The previous version seemed to attach better with a better seal to the stem.

Works great. Its a longer pump than most, but pumps up larger mtb tires faster. If you're in a hurry its the pump for you.

While the pump does work, its handle constantly pops while being used. Very annoying, makes it difficult to use.

I bought this Pump (from a different vendor), to use with both Presta and Schrader Valves. And it does work. But not without unscrewing the snout on the Head, then flipping two different inserts around, 180°; and re-assembling. It comes setup for Schrader. What's REALLY terrible, is that Blackburn has nothing to tell us how to do this nor that it's even necessary. I had to do an extensive Internet search; and happened across the manual for a Blackburn Outpost HV Mini-Pump. It was the only definitive instruction for this process. I've attached photos to make this clearer.

Very poorly made, it falls apart like a nature valley granola bar. Won’t connect and remain latched to either Schrader or presta valves. Immensely aggravating, and super impractical, will ruin any good time you’re having. Hypothetical time to inflate a tube is probably 4 hours of constant pumping, hypothetical because I’m still not even sure it will inflate a tube at all. It could be that I ended up with a defective one or something, because I don’t see any reason why anybody else has left positive reviews for this. It’s bad enough that I needed to come here to vent, and I definitely won’t be buying any Blackburn products if this is the level of quality they’ve been reduced to. I got mine as a gift so this is the first time I’ve seen the price tag for it, $45 is criminal to charge for this piece of garbage. You’d be better off trying to blow air into the tube with your mouth.

Ihren Härtetest hatte die Pumpe bei Schneeregen und einem Platten durch Scherbe. Gerade auf dem Liegedereirad mit 20-Zoll-Reifen bewährt sich der Zuleitungsschlauch, denn die Speichenkreuzungen verlaufen sehr knapp über dem Ventil. Das Ventil lässt sich zerlegen und die beiden Innenteile umgedreht wieder einbauen. Entweder Auto- bzw. Blitzventil oder umgebaut für Sclaverand-Ventil.Ich hatte die Fußhalterung einfach irgendwie aufgeklappt und losgepumt. Da die Pumpe kein Manometer hat, muss man sich halt auf sein Gefühl verlassen. Als der Reifen "knallehart" war, habe ich aufgehört, kurz das Ablassventil vom Übergang der Pumpe an den Schlauch gedrückt und bin weitergefahten.Daheim habe ich dann mit meiner Standlufgtpumpe mit Manometer über 5 Bar gemessen. Fast schon zuviel, denn so kann man beim Überfahren einer Münze schon Kopf oder Zahl erraten. :-)
