yes

Mine came with one, yes

no

Yes a cartridge is included.

no

Yes, but only 1.

Yes but is well worth buying the 6 pack of screw in canisters so that you can use the pump without its sheath.

Yes it accepts both threaded and threadless. Personally I prefer the threadless as they fit inside the handle of the inflator meaning your hands are away from the icy cold cartridge

Threaded

Yes it will accept both. You can also use other cheaper brands of co2 canisters.

Yes, both are accepted

Yes, it will

Yes, it comes with an unthreaded one but I bought the 6 pack of threaded ones straight away and think they are worth the money (more secure).

I find a cartridge is good for about 1.5-2 tyres, depending on the pressure you want. I always keep a spare cartridge on me though, just in case!

Yes the cartridge does need to be replaced after each use. I found there was a little CO2 left after inflating my 700x23 but not enough to be of any use.

yes, multiple use.

No. I have a CO2 pump and I just use as much out of the cartridge as I feel I need. Its like squirting a soda syphon. The pump I use has a lock on it to prevent gas from being accidentally released.

Be aware though that open cartridges are bound to leak over time.

non threaded are best

I bought a pack of 6 non-threaded Genuine Innovations cartridges from this site - cost about £15 I think.

I only get the 16 gram cartridges for mine
I think pack of 6 is £10.00.

I just use tha 16g cartridges, which will inflate a 700c x 25 tyre or a 26 x 1.75.

the infltor is 138mm long with head not fully screwed into CO2 cartridge. It fits my TOPEAK bag under my saddle which is not big.

It's 135mm long, if that's any help. Don't know the pack you're asking about, I'm afraid.

I Have a TopPeak Med size bag an fits in just fine. If thats any help
1 Co2 pump length 135mm
2 tubes
2 16 gram cannisters
2 tyre leavers
mobile
and 4 mm allen key
