I need a CO2 inflator for out on the trail.

Something that will allow me to cotrol the amoun of inflation rather than just dump it all in.

What do you recommend?

tru flow one allows that. for 7.99 cant really go wrong !

you got a link for that trail rat, was looking for one for myself, sorry to OP for the minor hijack

I use the tru flow one, which I bought solely on the grounds that it was the cheapest one I could find, and shockingly it fills up tyres with air in a perfectly effecient manner, and allows you to control the amount of air. I cannot see much reason to spend anymore.

thanks trial_rat, and cheers for the recommendation boatman

Is that a knob you rotate to adjust or push down?

The new Lezyne ones are also very good.

will one cartridge do a full 2.3 tyre?
Cheers

depends on size of cart

12g wont , 16 gram will get it up to late 20s psi

32 grams will inflate 2.3 no bother

What i tend to do unless racing is inflate a good chunk with hand pump till it takes lots of effort to get more air in. and then top it up with the co2 esp when touring and its rear wheel punctures. Get 3 punctures to a 16gram can (as you can shut off the flow on the truflo pump

When racing i just dump a 16g into 2.1 tires
