Blackburn Mammoth 2Stage AnyValve Mini-Pump

Mammoth 2Stage AnyValve Mini-Pump

Jamming along some choice singletrack and suddenly presented with hissing tire and feeling rim touching trail is certainly a buzz kill. Get your groove back and ride out instead of walking with Blackburn's Mammoth 2Stage AnyValve Mini-Pump. Its TwistGrip head locks to Presta, Schrader, and Dunlop valves for a sure and leak free connection and is rebuildable. This mini pump is specifically designed to push more air per stroke making it perfect for higher volume mountain tires, but its switchable high-volume and high-pressure modes allow for faster inflation with less effort and its 120psi max pressure makes it ideal for road use too. Includes bottle cage mount so it's easy to take with.

Big Volume , but only to 15psi

I've used it several times

Just like the prior reviewer stated, its hard to stabilize the pump head while pumping. The other problem is the high volume switch broke after a dozen uses. It doesn't pump any air in the high volume position. Ergo, I'm only able to pump my mountain bike tire up halfway before the pump stops working. Not in high volume or pressure. Zero star rating.

No room for your hand

I've used it once or twice and have initial impressions

I got this pump for the mtn bike. I tested it out the other day and found that the handle of the outer shaft moves all the up to the head and completely covers the inner shaft. This makes it awkward to pump up your tires because there is no t really any room to put your other hand to stabilize the pump while pumping. It was also hard to pump top off the tires to 30psi. The rubber plug only fits into the shrader side, so if you are using the presta side the rubber plug just dangles in the way. I ended up just taking the plug off. I probably wouldn't buy this pump again. Next time I will go with one that has a T-handle.
