SKS Airchamp Pro Co2 pump

SKS Airchamp Pro refreshes the parts other CO2 inflators cannot reach - or at least mine did when a cartridge accidentally engaged in the pocket of my shorts! That aside, it wins over similar inflators thanks to an ergonomic body and a clever thumb switch that allows controlled pressure release without jettisoning all the compressed gas in one hit. At £2.50 a cartridge, it best suits competitive riders who puncture infrequently. That said as commenters here have noticed, shop around and you can get threadless CO2 cartridges for a lot less than that.

Tipping the scales at 128g fully loaded, the Airchamp Pro has a lightweight composite body and reversible Presta/Schrader valve heads, complete with a dust cap to keep dirt out. It works with threaded and threadless valves (its sibling in the SKS CO2 inflator range is restricted to threaded cartridges. Designed for single-handed operation), it sits comfortably in your palm and is easy to use.

Obviously you need to load a cartridge before you can use it. Just unscrew the head, drop the cartridge inside and reassemble it snugly to complete the seal, making sure the piercing pin is correctly aligned. Slip the safety catch to prevent accidental triggering over rough roads or trails - and you're ready for action.

Come the dreaded hiss, you'll need to perform the time-honoured tyre and tube drills. Once the tyre and new or patched tube are back in place, fit the appropriate head to the valve, depress the switch (ensuring the safety catch is off), and rejoice as a 700x23 tyre inflates to 110psi in eight seconds.

Controllable gas release might not seem an obvious benefit to racers, but it's really useful for audax riders and weekend tourists wanting to top up tyres that even the most strenuous mini-pumping has left slightly soft.

While it works well with narrow road bike tyres, performance isn't nearly so good with bigger volumes. A single cartridge was completely spent inflating a 700x35 cross tyre to its recommended maximum of 75psi, taking 12 seconds. That's still pretty reasonable, although similarly stout touring tyres might want 90psi. On fatter off-road tyres it literally runs out of gas. A 26x1.9in mountain bike slick tyre consumed almost two cartridges - a fiver - to get it back to full pressure.

Verdict

Dependable emergency inflator that works best with narrow section road tyres

7/10

Expensive if used regularly and you are paying full retail for the cartridges - shop around and you can get the right cartridges for less than half that though.

Tell us how the product performed overall when used for its designed purpose

Raising a falaccid 700x23 to 110psi in a matter of eight seconds is pretty good going and could mean the difference between pole position or hanging off the back. Controlled release is another nice touch, allowing quick top-ups on tour or as support to the hand pump following a puncture on the club run. However, peformance is so-so on bigger section tyres and our safety catch wasn't completly fool-proof either.

Tell us what you particularly liked about the product

Nicely designed and pleasant to use.

Tell us what you particularly disliked about the product

Middling performance on wider section tyres.

Did you enjoy using the product? Yes

Would you consider buying the product? Quite possibly since I don't flat too frequently

Would you recommend the product to a friend? If they raced and weren't overly puncture prone

Overall rating: 7/10

Well if you're buying them from cycling shops then yeah it is gonna cost you £2.50 per cartridge. If you buy them from air gun shops or ebay you can pick them up for about half that, £23.68 for 25 on ebay, item number 230435267019.

All the gear and no idea!

What I'm still not clear about is whether this will allow you to carry a cartridge within it's own body unopened like the Genuine Innovations range does? If not does it mean the full cylinder floating around in your pocket with other bits? Indeed, if it has to be pierced to be fitted within itself does the pressure stay constant for a long time with both threaded and unthreaded cylinders or just threaded? Please let me know what the deal is as I'm about to buy a new CO2 inflator, left mine on the Puig Major in Mallorca, and like the looks of this one.
