Birzman Infinite Apogee Road Hand Pump with CO2 | Compact & Efficient Bicycle Pump | Presta/Schrader Valve Compatible

I really like the pump. It's the nicest looking one I've ever owned. The exterior looks really classy and stands out on rides. Lots of people have asked about it when I've had to use it which is normally a good thing.The attachment mechanism takes some getting used to and even once you're 'decent' at attaching it I would say the experience is a bit hit and miss. I don't see what's wrong with a more traditional system to be honest. Criticisms aside, once the pump is attached having the flexible hose does mean you don't need to worry about clattering the pump into a carbon wheel or bending a valve core so that is a bonus.I've used the pump for Road, MTB and Cross tyres thus far and it handles them all just fine (takes a good bit of pumping to inflate a 2.4" 29er). Are you going to seat a tubeless tyre with it? No, but that's not the point. The pump can be used with C02s which is useful but I tend to avoid doing this given the environmental and financial implications. After all, air is free.The pump is quite long which wasn't unexpected but is a little disappointing. It sticks a long way out of your jersey pocket which is a bit of a shame. On the flip side, it's not heavy so I never really worry about carrying it. The way the pump stays closed is another point of slight irritation. There's a weird sort of ribbed rubber gasket which keeps the handle from sliding out, I can't see this aging well. You also need to shove it out of the way every time you actually want to use the pump. Not that elegant given the cost.The pump comes with a frame mount which can also carry C02s which is nice. I'm unlikely to use this because it's not really my 'style' to have brackets attached to bikes but the inclusion and design of the system is neat.Overall, as I say, I like the pump, but there's nothing about it that suggests it should cost 3 times as much as any of the other excellent pumps around.

The pump is really effective. Got my bike tyres ready for the road in minutes. Design is smart making it very pleasant to use and easy to carry around. Small piece of kit that every bike owner should have!
