Review on 🚲 Crankbrothers Gem Hand Pump - Dual Piston Pump for Presta and Schrader Valves, Short/Long Design, High Volume and High Pressure for Cycling Enthusiasts by Robert Robertson

For the money this is a pretty cool little pump. It comes with a water bottle mount for your bottle cage to stand on and is highly adaptable to Schrader and Presta valves and also has 2 settings, one for low pressure under 30psi and one for high pressure around 30psi. Be sure to read the instructions for both of these adjustments, although switching valve styles in the woods can be tricky before taking it to the trail. The only thing I don't like is that the pump head spins freely, but I put a rubber band around the whole thing and it's been reliable on some rough trails. Great street pump for the money!
