Verdict: 
Good bottle cage with integrated C02 Inflator tool and cartridges for people who can't bear to put them in their pockets
Weight: 
229g

Topeak's Ninja range generally centres on hiding tools discretely away in your frame, but the Ninja CO2+ puts your emergency puncture fix on proud display, under the incorporated bottle cage.

It's a funny-looking set-up. I didn't like it at all when I first laid eyes on it. That chunky black plastic isn't the kind of thing I want near my Sunday best bike. The lumpy aesthetics are made worse by the integrated tyre levers that clip to the side of the bottle cage. However, I fitted it to my all-steel, purple-to-black-fade tourer/shopper/winter sacrificial bike and, once in place, I had to admit it looked a lot better; even more so once there was a bottle in it, which hides quite a bit of the item's mass. As a bottle cage, I couldn't fault it. It's made from very strong, flexible plastic and the grip is excellent. The mounting slots are long, which allows for plenty of positional freedom. You need to supply your own mounting bolts.

Topeak Ninja CO2 - Micro Airbooster.jpg

Secured underneath by a tidy Torx bolt is the inflator kit holder, complete with two 16g CO2 cartridges and Topeak's own 'Micro AirBooster' inflator. This is a neatly-machined aluminium piece, finished in a fetching anodised pink. The big end screws easily onto the CO2 can thread until the end of the cartridge is pierced. Then the inflator head is either pushed (presta) or screwed (Schrader) onto the valve. The inflator is spring-loaded, so a firm push down is all that's needed to release the gas. As soon as you relax the pressure, the flow is cut off. It works very well.

I like the way the tool mounts into the bracket, pushing into a clip and then secured by a knurled alloy knob which threads into the inflator head to keep it from falling out. The CO2 cannisters are gripped around the neck by a clip, then snap down into the mounts, where they never rattled or threatened to fall out.

Even the skinny-looking tyre levers were up to the job. They attach to the side of the cage mount by hooking over a plastic pin and slotting down to lock them in place. In use, the hooked end becomes a spoke hook and they made easy work of shifting the tyres I tried them on.

It all just leaves the question of what problem Topeak are trying to solve with this product. I've always carried my CO2 inflator in my pocket or tool pack and, in putting it on show under the bottle cage leaves open the possibility of theft when your bike is parked in a public place. But if you don't like carrying things in your pockets or using a saddle pack, it's a viable third way.

Verdict

Good bottle cage with integrated C02 Inflator tool and cartridges for people who can't bear to put them in their pockets

Tough as old boots! The inflator tool is also well made.

6/10

Without the tool and inflator cartridges the cage weighs 95g so not really one for your UCI-troubling bike. However, it is very secure.

6/10

With CO2 inflators typically costing between £10 and £20, http://road.cc/content/buyers-guide/183431-14-best-cycling-tyre-pumps-an... and bottle cages coming in at under a tenner to over £40 the whole package for £40 isn't bad, assuming you don't already own a CO2 inflator.

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

Very well. The bottle cage was secure and strong, the inflator tool worked just as it should and the tool mounting bracket was also a neat design that held onto its load securely. Even the tyre levers are good.

Tell us what you particularly liked about the product

I liked that I was prepared not to like it, and them I did.

Tell us what you particularly disliked about the product

Chunky plastic looks (though it looked much better once fitted).I thought the risk of theft might put some people off.

Did you enjoy using the product? Yes

Would you consider buying the product? No because I already own CO2 tools.

Would you recommend the product to a friend? Yes

Use this box to explain your score

Topeak have come up with a good design and executed it well, Everything worked as it should, it is all well made and even the looks grew on me. However, you need to accept the premise that a bottle cage is a better place to keep a CO2 inflator than a pocket.

Overall rating: 8/10

Probably fine with only 1 bottle cage, but I don't think it would fit on any of my frames with 2 cages, even if this one was on the seat tube.

Was thinking exactly the same. If I only needed one bottle then I could store far more in a cut off bottle in the second cage.
