Review on 🚲 Topeak Hybrid Rocket HP Mini Pump - Silver/Black, 7.5 x 1.5 x 0.9-Inch Without Cartridge: Compact and Efficient Bicycle Inflation Solution by Brian Kingsford

The mini pump is great. The extendable hose is great. The CO2 valve sucks. And that was after a lot of shaking and shaking to get all the CO2 out. I then re-inflated with a 20g cartridge with another pro inflator valve and got 67psi out. I love the pump design and the multifunctional concept, but Topeak's engineers need to overhaul their CO2 valve. My theory is that the emitted carbon dioxide is icing and clogging the valve. Also on the pump side where you turn the valve to inflate the tire. Be careful as he can (and did for me) unscrew the valve core on the inner tube. So all the work you put into inflating a tire can be undone if you unscrew the pump.
