Axiom's Expand Air HVG is a telescoping mini with a fold-out ergonomic T-handle, a built-in gauge and a sturdy plastic-composite barrel for high-volume pumping power. Its reversible thumblock head fits Schrader and Presta valves and has a cap to keep dirt out. There's also a frame mount so you can always have the pump handy.
I found the pump handle would slide off sometimes when riding and it would end up sliding on the chain wheel, but I flipped it to the left side and have not had a problem since.
It does not replace a real pump but works when you are out on the trail.
Bottom LineYes, I would recommend this to a friend
