Thanks, although unless the Road Drive pump contains some tech I'm not familiar with (such as a dual-stage or switcheable HV/HP modes) I can't see how it can achive high pressure / high volume / low effort at the same time - that would be defying the laws of physics.You can hate Lezyne all you want, but the truth of the matter is, they make the best pumps, and their Road Drive pump in the large size pumps to higher pressure with fewer strokes and less effort than any other mini pump on the market. Road Drive comes in 3 different sizes, you don't want the 2 smaller sizes. BUT, these are mini pumps, when you get 100 psi it will be tough, that is the nature of mini pumps, but most mini pumps won't reach 80 psi no matter how high they claim they can go.
If the Lezyne was too much work for you to pump up to pressure then you don't need another mini pump because they'll all be worse than what you had, so I would suggest a full-size frame pump. Zefal HPX4 is a fantastic pump for the money which I think is better than the Topeak Road Morph, I have both of those and I prefer the Zefal. Another great frame pump is the Silca Impero Ultimate II, this one is the high-end deluxe pump that will last a million years, but it will cost you about $100 on Bike Tires Direct and about $175 on the Silca site, you will need to know your frame measurement between the headtube and the seat tube.
Now, you could go with the CO2 option, if you do that look into a hybrid model, a hybrid will have a regular pump and a CO2 inflator built into it, that way you won't be stranded, or keep your Lezyne and buy a CO2 inflator. What you would do is put about 20 psi in with a pump then use the inflator, you do have to practice with them a bit because they can be tricky the first couple of times and you don't want to waste cartridges out on the road and end up with no air. The drawback with CO2 is that it will bleed through the tube fast, and the tire will be flat in about 24 hours, so that means when you get home after using CO2 you would have to completely drain the air out and pump in fresh air. The other disadvantages are that you have to buy CO2 carts, and you have to bring home the used ones to discard them properly. All those reasons are why I refuse to go with CO2, but we each have to make our own decisions as to which is best for us.
My experience of Lezyne has definitely been poisoned by the sub-par POS they market for the Brompton, however at least they managed to make the piston area a bit smaller to suit the higher output application.. perhaps their other offerings are made to a better standard than mine was.
I agree that mini pumps are poor for high pressure, and my research suggests that you're not going to get north of 40-60psi comfortably without some form of propriatory system, or in the form of a pseudo-floor-pump like the Morph that allows you to put a lot more effort in.
I'm not sure a frame pump would have helped unless anyone does a dedicated high-pressure job, and in any case would haev been a moot point on the Brompton. What sort of pressure can you get out of your Zefal?
As per my previous posts I'm not doing CO2 for all the usual reasons...
I think you were lucky to get to 80psi if it's rated at 100! Sounds like it does the job thoughI've also been in the market for a mini-pump recently. I never used to carry anything, chancing my luck on not being too far from home and/or being able to limp to a friend's house, shop or rail station. I got given some CO2 paraphernalia for Christmas (though not by anyone with experience of them) but, when I actually needed it a couple of weeks back, entirely failed at being able to use it.
I eventually plumped for the Wiggle/CRC Lifeline Performance Road mini-pump, which arrived today. Good reviews, claims max 100psi, has an extendable hose, and (for better or worse) is properly mini (18cm, just about fits in my saddle bag). I just tried it out on an old, deflated 700x25c tyre and got to ~40psi in 150 strokes (easy peasy) and ~80 in 300 (significantly harder, but with stable grip and rhythm it kept on going, bless it). I've not tried it on the 700x35c tyres (max 65-70psi) of my current bike, as deflating a perfectly good tyre makes me anxious... but I'm going to assume it'll be fine, if maybe needing a little longer due to the increased volume. We shall see!
ETA: just thought I should mention, my pressure measurements were just via swapping with my track pump, I don't have a separate gauge. So YMMV.
So... the opportunity to use the Road Morph in anger presented itself on the way into work, with the experience being far more positive than the quick test it previously had.
The foot deployed easily, the head went onto the scrader valve easily enough and seemed secure and had the tyre up to six bar very quickly in 80-100 manageably strokes. Bizarrely, unlike last time I had zero issue with my knuckles striking the pump body this time - presumably because my grip was different but I can't really see how..
Other than the difficulty in reading the pressure gauge I can't really fault the pump's performance today and if continues to behave in this manner I'll be very happy with it.
Of course there are a couple of caveats - this was the front tyre so "only" needed six bar / 87ish psi (I usually put in 80psi, but that scale's impossible to read) while I'd want seven bar / 100ish psi in the rear. On top of that as per my last post I didn't find the valve head a particularly good fit on the Presta valve.. and I see no reason why this should change.
Anyway.. I was considering returning it and getting the Lezyne; however it's acquitted itself well today, so unless there are any really grimey problems with the Presta valve I'll be happy to hang onto it
