I already carry a small 12v electric bike pump on my bike just in case of punctures, however I've been looking at getting one of these beautiful looking bits of kit to save weight and stowage space.

I reckon that I could gaffer tape this tiny unit into the unused blank area at the back of my R/H pannier along with a few 25g co2 cylinders and forget about it until an emergency arises when I might need it.

Pros:- It's extremely light weight, fast to inflate, it won't blow a fuse, or seize up, or suffer from damp or upset my bike’s canbus.

Cons:- Perhaps running costs, however I haven't had a puncture on a tour in the last 5 years (I'll probably wish I hadn't said that, especially as I run PR4's) so if I'm fixing a puncture in the middle of nowhere I won't be worrying about the cost of a few CO2 cartridges.

Has anyone gone down this route as an alternative to carrying a 12v pump?

Oh…. and can someone get the picture up, as I’m struggling to load it?

It looks like an extremely well made tool...a nice piece of kit, with a lifetime guarantee something nice to own, if you appreciate that kind of thing.

So my question is...Has anyone gone down this route, or got or tried one of these pump valves?

PS. I'm well aware that there are lots of much cheaper units on ebay.

ummmmmm... a link to what it is you are thinking of getting may help :blast
 
Link worked for me. There are plenty of similar tools about some might look as well made as that. The biggest problem with them is that they don't inflate the tyre anywhere near the proper pressure even after using 3 cartridges. They are to get you to a airline. I carry something similar myself for comuteing but if I was to venture far I'd take a compressor. JJH
 
ive used those on bicycles and there great but motorcycles would need more then one for sure....
would be ok to use then straight to a garage to air up to pressure.
 
Just out of interest I was on the Motorworks site and came across a kit with inflators and repairs for £14. There are many options out there. JJH

FWIW, I recommend keeping the 12v pump and having CO2 cartridges and tyre foam in addition if you have space. I once had a series of punctures in the rear tyre in a remote area of France, on a Sunday... I plugged the first one, pumped up the tyre, only to discover a 2nd site. Plugged the 2nd one, pumped up the tyre and it still lost air over the next 15 miles, so I added a can of tyre foam into the tyre which finally fixed the leaks and enabled me to get home. If I'd only had the usual 3 or 4 CO2 cartridges I would have been stuffed, but with a tyre pump you can try again... and again... and again! The other advantage of having a tyre pump is that you can help a mate whilst on a long trip and still be able to fix a puncture in your own tyre if needed.
 
All of that sounds good to me Tomcat,

While searching for the co2 cartridges, I found some that you can actually get some that are already filled with 'slime!'

For those who don't pedal bikes, 'slime' is a self-sealing gooey foam, that (hopefully) fixes any smaller air leaks and punctures, as it leaks out through the hole it heals the wound, quite good if you have plugged a repair that's still weepy, however I don't know how a TPI might react to it.
 
Genuine Innovations did some great kits with 45g cartridges - these are enough to get good pressure in a tyre. For some reason these seem to have stopped in the UK now which is annoying, but I did buy a few of them as they were selling off cheap. The other option is a compact hand pump, sometimes you can fit these into little spaces.

Technically they must be able to deliver enough pressure, it's just that you need to use more cartridges or use the larger 25g cartridges then you'll use less of them. :thumb2

Wot he said.
I have had 3 punctures in 2 years plus fixing 2 unprepared mates punctures. Pump every time.
 
yeah a pump is best bet...i have a pump with a cigarette type car adaptor on the end..the bikes battery i connected a female type plug to the the adapter. It avoids any can bus issues if the pump you are using is too powerful .
 
What's the smallest compressor on the market that's canbus compatible?

I don't think any of them are 'cabus compatible' some people are able to use certain pumps when others can't.
It is best to install devoted wiring to be on the safe side.
I use this http://www.airman-uk.com/all-products/tour it has proved to be robust and reliable. It will not run with the canbus.

Buy any car type compressor from any motorist's shop, the cheaper the better.

Take off the cosmetic and bulky case.

You now have one small compressor in your hand.

It might, if you are lucky, draw less than five amps and will not trip the canbus. If so, job done.

If it does trip it out, power the compressor via a fused (7.5 amp might well do) lead direct to the battery or via a relay. Job done.
 
Snap!

I already have a small car pump, the AA Mini Air Compressor and I have fitted a plug that allows me to power it from my heated jacket socket, and my jacket socket is hard wired direct to the bike battery via a 7.5 amp fuse, so I'm covered for the power pump.

However, I'm a belt and braces man, and I just fancied the look of that beautifully made bit of kit.
