🚴 Efficient Blackburn Mammoth 2Stage Anyvalve Bike Mini-Pump for Quick Inflation Review

Product works great and is well made. But it's bigger and heavier than I expected. I should have paid more attention to the product specifications. Too big, bold and heavy to attach to my MTN carbon bike.

The pump does an excellent job inflating my fat 4.0 inch tires. The main thing I dislike about this pump is the limited space I need to grab the stationary part of the pump around the valve head. As soon as I squeeze my finger or hand in full motion, I quickly realize how little space there is. Inflates easily and quickly, but I don't think I'll buy it again. Why five stars? Because it actually fills the tire like a pump is supposed to do.

This is a really terrible pump. In high-volume mode, it takes a lot of power to drive the pump, even when it's not connected to a tire valve. Adding a deflated hose makes the pump even more difficult to use. In the high-pressure mode, the pump is quite easy to use, but does not allow to use such a large volume. The mechanism that must attach the pump to the valve is also very weak. I couldn't get more than 18psi in a 27.5+ tire without spontaneously dislodging the pump head from the valve. And…

I've used this pump on the road a few times and have tried it on all the bikes in my garage too. It definitely produces a high volume of air and pairs well with mountain bike tires. Taking a street tire up to 100psi in high-pressure mode is doable, but it's a chore that requires some effort. A notable downside to a pump is that you don't have much room for your stationary hand to hold the pump (to hold the pump securely on the valve and have something to squeeze) since almost the entire shaft…
