Hi Pressure Mini-pump

[Brucey]

In a perfect world, you would be able to buy a pump that does

- 150psi
- high volume tyres
- has a built-in gauge
- is tiny
- weighs nothing
- is easy to use
- costs peanuts
- lasts forever.

by comparison with which, the OP's requirements are fairly modest.

IMHO from the above list 'choose any two, forget the rest' is a realistic objective.

One of the few tiny pumps I have used that will genuinely do 120psi is the Topeak Pocket Rocket DX. No gauge, and it does take ages though, even on skinny 23C tyres. On anything longer than day rides, it is still a much better idea to carry a frame fit pump like a Zefal HPX (I wonder how that stacks up against the Lezyne BTW...? Anyone got both..?) and in any event have a track pump at home.

Mine doesn't have that, it's just the screw-on.
Yes, it needs screwing, but it's secure and doesn't leak. It's reversible for Shrader of course.
I don't find it bothers the tube or valve at all.

For normal riding, I take CO2 canisters and only take the Lezyne if I'm away for days. I'm (hopefully) off up to Bedford to stay with Daughter2 later this month, and my Lezyne will go with me. Tyres need topping up every day or two, so a pump is the preferred option for that, with the CO2 just for emergencies locally.

Brucey:
150psi I would think, but I only go to 120psi.
Tiny
Weighs hardly anything
Very easy to use
Not cheap!
Dunno how long it will last.

The Lezyne pumps like the one I linked come in two variants: High Pressure or High Volume.

I've had an HPx for ages. It came from JD Whisker's "Our stock is our gimmick." ! ! !(That's the nearest I can do to three cheers.)

An excellent frame fit pump but IME anything rigid of that push-on type is likely to waggle to valve off, especially when you get to the extra effort of getting to higher pressures, so it needs a lot of care in use. I've not got a Lezyne but I have a Road Morphe and it has most of the benefits of a full-size track pump (of which I have 2 ) The Morphe has a push-on adaptor but the flexible hose means that pumping doesn't waggle the valve.

What I was trying to get across in my earlier post is that I think these mini track pumps are really ideal for those occasions when you would like to have a proper track pump available but you can't hump one around.

[Brucey]

FWIW if you think you might 'waggle your valve off' then I would suggest that your valves may not be a good fit in your rim.

There are many rims sold at present (even by reputable manufacturers) which are defective by design, having (especially with presta valves) one or both the holes in the rim large enough for an unbonded valve stem to pass through. I daresay that waggling might give such arrangements the kiss of death, but in reality they are quite likely to fail without waggling otherwise.

I try to make a point of fitting ferrules to such rims so that the valve cannot fail in this way.

I also use one of the Lezyne high pressure pumps on my best bike but the £6 price of a spare mounting bracket for another bike put me off, as did the thought of having to move it depending on which bike I was using. By chance I spotted one of these in Poundland - so took a chance and bought one. Out of the packet it is set up for Schrader valves but taking the valve cap off and turning the rubber washer and the lower support around it works for presta valves. When I first tried it the high pressure required by my 23mm tyred road bike caused the rubber washer to extrude through the screw on pump cap but inserting a washer with a 6mm hole has cured it and for a quid I think it is good value. It also pays to inspect the innards and remove any excess "flash" from the mouldings. It does suffer from the same low volume that afflicts most pumps of this size but as a get you home pump it is perfect. I also use an additional strap to hold it tight against the frame.

I have one just like that poundland job, but got it at Tesco years ago. I was my favourite mini pump until we got the Lezyne- and I've been through lots of others including specialised, blackburn, and the worst in the world, a crank brothers. The handle broke, but I managed to push it back on and it's now my back up.
