What pressure can one expect from one of these, in a mountain bike tyre and a road bike tyre respectively?

Ta!

HIJAK – and how many for a doll?

No idea matey but I have used one for my roadie and a MTB in the last month

They seem to have the right amount of gas in for each TBH
ie low vol but high pressure for road and high vol at low pressure for MTB

I didnt measure but both felt spot on

Coolio, thanks sporticus. I presume a couple would achieve a fleshy nubile plumpness on a doll then…

bout 30 psi in a 2.1 mtb i reckon, 20ish in a 29er, 80 in road

~50p here, higher pressures quoted than my experience

according to the Tyre Inflators website a 16grm cartridge :

Will fill:
1 x Road Bike 27" tyre to 130PSI/9BAR
2 x BMX 20" tyres to 30PSi/2.1BAR
1 x Mountain Bike 26" x 2.1" tyre to 40PSI/2.7BAR
4 x 16gm will fill Motorcycle 180/55/17 tyre to 32PSI/2.2BAR.

Whatever you do don't buy a Weldtite one

I had 3 & all failed from the word go – they wouldn't pierce the canister

I gave up & got a Truflo one

when i have used them i would say 20 psi for a 2.1 speed king.I always top it up with a pump as the gas itself isn`t enough to keep going

Mr Monkey,

top site, thanks. They'll be my supplier from now on
