Review on 🔧 Mini Bike Pump with CO2 Inflator - Dual Mode Hand Pump & CO2 Valve - Portable Tire Pump with Patented Auto-Switching Twin Head Fit Presta/Schrader - (Cartridges Not Included) by Pedro Curtis

Pros: Solid feel, good inflation speed, small size, works with Presta and Schroeder valves, bolts onto Presta valve stems, includes CO2 reservoir. Cons: It takes some time to get used to not moving. When pumping you can't buy a separate mount for the pump, some CO2 cylinders rub against the downpipe. Overall I'm very happy with this pump. I would recommend it to anyone looking to install a pump and C02 cartridges on a frame. The pump fits perfectly into the Presta valve stems, has a fairly large volume and is easy to use. My only real issue is that you can't order/buy separate mounts for use on multiple bikes. I would easily pay for separate racks for the three bikes I use.
