Birzman Infinite Road + CO2 pump



Efficient inflation, with the added bonus of the option of CO2

The Birzman Infinite Road + CO2 pump is a 2-in-1 pump and C02 inflator is a good-looking efficient machine to get you back on the road in the minimum of time.

Added bonus points are scored for looks and additional features that perhaps you wouldn't expect. First the looks: made from precision CNC'd aluminium alloy, the body is sleek but meaty enough for the job. The stated pressure the Infinite can achieve is 160 psi. Most users won't need that much unless using tubs so you'll be fine.

The hose is tucked away neatly within the body and kept securely in place with a rubber cap. This prevents the hose from falling out of the handle and the rubber stopper is fitted very securely.

When you slide the hose out you are faced with another well-made piece of CNC alloy. There is no fiddling around making sure the hose attaches securely due to the chuck that fits both presta and schrader valves. The chuck works by attaching to the valve and then sliding the outer body up to keep in place. Once you've tried it a couple of times you will find it fits well.

Another one of those unexpected features is the chuck also allows the use of a CO2 cartridge if you want to go for the quick inflate.

This was my first experience of using a CO2 cartridge as I've always been a little sceptical in the past. What if you don't attach the hose or fail to thread the cartridge? Neither of those happened; there is a small sleeve to fit the cartridge as they do get cold. Attach the hose and then screw in the CO2 and away you go, happy inflating.

The pressure achieved is more than sufficient to get you going again. With a bit of effort I managed to get at least 90 psi just through manual labour. Using the combined forces of hand and CO2 did achieve slightly higher, not bad.

Once you've finished you can secure the pump to your frame using the neat carrying bracket that will also house your CO2 cartridges.


Efficient inflation, with the added bonus of the option of CO2.

Size tested: One size

Tell us what the product is for, and who it's aimed at. What do the manufacturers say about it? How does that compare to your own feelings about it?

All riders will have need of a pump at some point, one of cycling's un-written rules, what you don't want is one that wears you out in the act of inflating your tyres.

Tell us some more about the technical aspects of the product?

The Infinite has a smooth action and a screw lock to keep it compact. The hose is tucked away in the handle and is compatible with both valve types. The use of a 'chuck' on one end of the hose allows the other to be attached to the pump or a CO2 cannister.

Rate the product for quality of construction:

Well made from CNC'd aluminium, the Infinite has a solid feel but that doesn't make it heavy. The pump action is smooth and using CO2 cannisters straight forward even for a novice like me.

Rate the product for performance:

Impressive figures. The company state you can achieve 160 psi with this pump but I don't have tyres suitable for this pressure. The tyres I do have were easier enough to get towards 100 psi.

Rate the product for durability:

Given the quality of the materials and construction, this should be a long lasting product.

Rate the product for weight, if applicable:

Not the lightest pump but it is dual use so no qualms with the weight.

Rate the product for value:

Again the fact that it can use either manual or CO2 make this versatile and I think the cost reflects this.
