Dual piston mini-pump with high volume/high pressure switch promises not to disappoint. As with most Crank Brother products, this simple durable design was well thought out and should function for many cycling seasons.
This pump works well, considering its size. However, dont expect it to fill a tire as quickly and easily as a full size pump. Make sure it is screwed together snuggly, and also make sure to use the twist lock. Nice.
I lost my first one when I left my saddle bag open. I cannot live without it. The pump offers two settings: (1) high volume or (2) high pressure. I am not sure that the first review understood this. It is the smallest and most versitile pump Ive used in my 20+ years of riding on and off road. I love it!
Nice and small but only good for mountain bike tires. Takes forever to get to 80-90psi and really hard at the end.
