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 Tim Larsen

I put this pump in a water bottle along with the CO2 cartridge, spare hose and patch kit. It ALL fits in a regular water bottle and now I can use one of my bottle cages to carry my home renovation kit. Not only is it compact and lightweight, but it can also operate without CO2 if required. My kit came with one cartridge as noted by another reviewer. The product description says it doesn't come with a cartridge so your luck may vary. However, the packaging is clearly equipped with a special compartment just for storing and presenting the cartridge. So if you're lucky, you'll get one too.
