Long story (sorry)
Many moons ago I bought a used MTB which came with a very nice Rockshox "high pressure" mini pump that had a guage on it. That is just the jobby for my road bike tyres I thought as my other mini pumps (one on my MTB and one on my hybrid) do not have guages (yes I know now). So for 5+ years I have been carrying this pump with me on my roadie. As it didn't come with a mount, I have had to invent ways of attaching it to me / the bike, none of which were ideal.
So recently my frustration levels got to the point that I deceided to try and find a mount. However, my search was fruitless. It did, however, unearth one important issue - the pump is not a tyre pump! It is a suspension fork pump. So all these years I have been carrying it, it was useless, so it was very lucky that I never had a p*uncture during that time.
Well cut forward to last Saturday (1st July). I had planned a nice 50 miler. So I needed to take a pump that worked. I had a Mini Morph, but the only mount I had was a standard mount which won't fit the roadie as the bottle cage is using the mounting holes. I needed a side mount so it would fit under the bottle cage mount. I do have a side mount, but that is on the hybrid. I also could not find one online anywhere as it seems they have stopped making them. So after much effort I managed to tie wrap the standard mount to the side of the bottle cage on the roadie so problem solved and off I went.
Well would you credit it, 35 miles in I get my first p*uncture on the roadie (rear wheel). So spare tube in and Mini Morph comes to the rescue.
So for all the years I carried a useless pump I had no p*unctures, the first time I ride with a pump I can use, I get a p*uncture. Truth, as they say, is stranger than fiction.

The pump would have inflated the tyre, it would have taken a while though. :laugh:

I don't think it would. Aren't all shock pumps Schrader valve only (mine is)? No good if you are stuck on a road bike with Presta valves.

The manager of my local bike shop told me there has been a couple of attempts over the years to produce a combined shock and tyre pump.

None worked.

Pressure and volume is close to mutually exclusive for a hand pump.

I once tried to inflate a 20" balloon tyre with a Blackburn roadie airstick.

Try as I might, I could only get the tyre podgy, certainly not firm enough for an adult to ride.

Yes and have you ever tried to inflate a road tyre with a fat-barrelled mountain bike pump?

I lent my Lezyne HV (high volume) pump to a guy with a road bike.

He managed to get enough air in to get going again, although I suspect tyre size is critical.

His tyres might have been 28 or a bit wider.

My pump would probably be a dead loss on 23/25.

I have a couple of those adaptors and they seem to be fairly useless once you get to about 60-70psi and then leak more than pumps into the tyre.

You were doing something wrong then. A small pump should have no trouble getting a fat tyre to the required 30-40psi, although it may take longer than a high volume pump. I have inflated big MTB tyres on a few occasions with nothing more than my Topeak Pocket Rocket and to be honest, once you get the technique and rhythm right, it doesn't take as long as you might think.

Yes. I have an old Zefal aluminium tubed MTB pump and can just about get to 60psi before I give up because the physical effort becomes too much.

The Topeak Pocket Rocket is significantly longer - in pump terms - than my Airstick, and it may be a bit fatter.

Mine was also the basic single chamber version.

It really was hopeless on a balloon tyre, but I suppose it may have got there eventually.
