Review on 🚲 High Pressure Bicycle Tire Hand Pump - LEZYNE Pressure Drive, 120psi, Presta & Schrader, ABS Flex Hose, Compact Bike Pump by Nelson Calafell

It is always a good idea to have a hand pump on hand for long journeys. Refilling a CO2 cartridge is a one-time affair and if you screw it up, you're screwed. Also, CO2 refills are temporary - CO2 tends to leak out of the rubber hoses. This pump has a convenient mounting system that fits between the bottle cage and the frame. The pump itself is held slightly offset parallel to the frame tube. I found it didn't interfere with my seat tube mounted pedaling. I have an apartment and have had to use the pump since I bought it. Getting 80psi into a 25mm street tire with one of these things is by no means easy, but the pump is certainly smaller and lighter than a good floor pump. This is a compromise. This pump easily fits lower pressure CX or MTB tires. I would go for a larger pump if I plan to run higher pressure tires (e.g. 19mm tires or tubulars or if I was a heavier rider).
