Mini pumps

I have v mixed feelings about Lezyne pumps particularly when pared with Conti inner tubes. They have a tendency to take the detachable valve piece off. Much prefer lever end as opposed to screw on ends for micro pumps

They sell a seperate lever end that you can fit to most of their pumps. (I had the same problem with my cross tubs).

i am the opposite, i think the screw on rubber end puts lets stress on the valve.
as opposed to pumping with a fixed lever type thingie.

What no hammer?

that fncks them up straight away

^you must be hammering it wrong.

Hammer upwise!

Okay I'm sold on the Lezyne but which one is the best in terms of small but giving good pressure?

Lezyne Alloy Drive Mini Pump

Lezyne HV Drive Mini Pump

Lezyne Micro Floor Drive - HV

Not as small as the others, but I am sure will outperform all of them by a huge margin. But its definitely small enough for any regular or large size cycling bags (courier or rucksack type).

Specialized Windpipe. Pumps to 220psi, and I can tell you that there is almost no effort in pumping to above 140psi....at which time I had exploded a tube and tyre. Its almost too easy. And the guage is very accurate.

Surely this Blackburn is worth a punt for £9?

Does anyone know anything about these pumps?
Looks nice and sounds good

oh sod that, going for the lezyne hp mini

Lezyne Alloy Drive Mini Pump

Lezyne HV Drive Mini Pump

Lezyne Micro Floor Drive - HV

So what's 'pressure drive' then?

I'll need this for my sweet fixie and my smooth DJ bike with 26ers BUT most importantly it needs to fit in to the loops on my awesome BRP Violet pouch (ie. Small)
Which one?

EDIT, There's also HP (High Pressure) Drive apparently

^Lezyne do versions for MTB/fat tyres and for road bike skinny tyres. Tommy's post is all the MTB versions.

HP is high pressure for roadies and HV is High Volume for MTBs

i.e. Alloy Drive is rated to 90PSI and Pressure Drive to 120 PSI

Right, so as a compromise, the pressure drive should accommodate both?

There's a swivel drive available also, for those 'hard to reach places' (?).

Yep, Lezyne hoses have both a Schrader and a Presta end so you'll be good to go.

Nuda Carbon / titanium mini pump for racing tyres, 39g good to 10 bar (150psi) -£20 from Decathlon - mine works really well.

Lezyne pumps are made of pure win. True FACT.

1+ lezyne or bust.

This is my reasoning to why Lezyne are awesome -

have you ordered one yet wicksie? can you let me know if it fits your violet alreet?

Haven't yet. Just bought an Indigo so won't be buying anything until payday! Do you have a violet now?

Yeah managed to buy one from another forumite, Scott told me he wouldn't be making any more for a while and reckon a violet suits me needs better than an indigo.

Specialized Windpipe. Pumps to 220psi, and I can tell you that there is almost no effort in pumping to above 140psi....at which time I had exploded a tube and tyre. Its almost too easy. And the guage is very accurate.

I had mine fail (a bit) yesterday - an air leak where the hose meets the nozzle. It may just need tightening, but the guy at the Evans that I had gone to, had no idea how this pump could be repaired. I think I'll have to contact Specialized directly. But in the meantime, I replaced it with another Windpipe, as all the mini-pumps I looked at, could not compare to the power and efficeincy of it. I got it again from Evans, like the first one, but wangled it down to £24.99, as opposed to the £29.99 shop price. Its advertised in their online catalogue as £24.99 for the 2010 model, but since there in no difference between the 2010 and 2011 models, I got it as advertised. I'll give feedback if Specialized prove to be of any help, but I don't expect that to be very quick.

I have this one, works well, though I'd (now) prefer something with a hose to minimize the chances of damaging the valve stem. It fills on the push and pull, so not as tedious as some.

^How did you find the build quality on yours? I bought one a while ago and my impression was that it's a genius idea let down by cheap construction. The finish on the aluminium middle cylinder was disappointingly rough and high-friction against its seals, while mould lines on the inner plastic plunger/pressure gauge caused its seals to leak, and the valves between the pressure gauge and the inner cylinder just don't work, so the gauge doesn't function and the pump relies on the tyre's valve instead, loosing some more efficiency.

Which is a real shame as it's a really good idea for a pump - the 'in' stroke doesn't force all its air into the tyre but instead compresses it into two thin annular spaces between the plungers and their corresponding cylinders. This effectively takes away the hardest last bit of the 'in' stroke and spreads it over the whole of the 'out' stroke, allowing the pump to be both high volume and high pressure at the same time.

Valve stem damage should be a lot less of an issue with this scheme as it avoids the jerky high-force bit at the end of a conventional pump stroke.

The alu on mine is pretty smooth, no leaks as yet.
Gauge still works too, though I would like markings at 50, 75 and 100 PSI.
I can see how the mould lines might degrade the seals over time.

I had to dismantle and polish out the mould lines before mine started working. Maybe they've got better at making them since i bought mine.
