Tyre Pump

[nobby]

I think that I have understood that low pressure 'fat' tyres are better inflated with a pump that has a wide body (high volume?) and, of course, my pumps are thin bodied road pumps.
What pumps are people carrying, please?

I've got some old style of Blackburn MTN in one bag and a Lezyne mini MTB thing in another. Both do the job just fine.

Lezyne mini pump here too.

Like Ian I take a small pump

Since I started riding without a camelback I have pared down the junk I carry. The pump is small and I hope I never have to use it !

I dont have 'fat' tyres though, just ordinary 2.0 / 2.1

I have a Lezyne pressure drive for road bike purposes (high pressure low volume)

and

for MTB purposes, a Lezyne something or other Drive - which is in anodised blue bling so I can differentiate it between my road pump. It's a high volume, low pressure jobby.

Top notch quality if a bit pricey

I thought 2.0/2.1 was fat. After years of inch and a quarter they look fat!

Thanks all.
Those Lezyne look lovely and my lbs stocks their road pumps. I'm in there tomorrow so I'll see what he has hidden away from his roady clientele.

I've got the Bikehut branded version of this:

Does the job ok and won't break the bank. Much prefer it to "direct to valve" pumps. I've also got some stupidly light BBB one that I take out on my road bike. It'd be a nightmare trying to inflate a flat 29x2.0 with it!

I went to lbs yesterday and I was that astounded that he made me a coffee that I left without buying anything.
Went back this morning and looked at the Lezynes (and got another coffee) and got a good price on the Flatfishy one at the top of this thread.
Mine has a gold anodised screw on bit; very bling. :) I'm summoning up the courage to tell Herself how much it cost.

...and I've just seen it is a HP not a HV.
Does it make a lot of difference?

[Taylor]

Yes.
HP = high pressure, for roadies.
HV = high volume, for mtb's.

Yes.
HP = high pressure, for roadies.

I guessed that bit but what's the practical differences?

[Chew]

Think one pump from a HP pump as 5cm of air at 150psi, whereas HV is 50cm of air at 50psi.

Your HP pump will work, but it'll be a lot more work. (plus you'll hopefully never need that kind of pressure)

See if you can swap it?

Yep, no trouble swapping it. It's a roadies shop but they've ordered on in for me.
Ntw, another excuse for an urban snow ride and a Costa :)
