I have this one specifically: http://www.amazon.com/Genuine-Innovations-Ultraflate-Plus-Inflater

Pretty sure I didn't pay that much for mine, though!

Of course, not knowing what you don't like about the Spin Doctor makes it impossible to say if a Lezyne will be better suited, but I've got no doubt that the Lezynes are better tools.
Hi Chad,
I'm just not a fan of the size. I'd like something smaller I can fit in a tool roll.

Thanks Chad! Are these all Presta valves? I've got Schrader valve on Lola's 700x38 tires.

Not necessarily. There are several design elements that make some mini pumps much better performing than others. I don't doubt the Road Morph moves a lot of air, but the tradeoff is that it's a big, honking pump. I'd add also quite ugly. The OP asked for small and thin, in fact, smaller and thinner than her Spin Doctor. The poor girl; in 25 posts, she's actually gotten only 3 reccos that directly answer her request!

Anyway, regarding pump efficiency, things like shaft diameter, friction, and rigidity, and material all affect efficiency, but in the end, we really have a decision to make: high volume for quick fills, or high pressure for easier filling at the top end. To illustrate, the Lezyne Pressure Drive will hit higher pressure in 1/2 the strokes it takes the longer Blackburn Airstick (http://www.cyclingactive.com/bikesge...est-mini-pumps).

A clever solution to this quandary is found in the Crank Brothers Sterling mini-pumps, which offer quick switching between high volume and high pressure modes, so the pumping effort stays low throughout the effort while maximizing volume output. The Sterling G, at 7.8", is also shorter than the Spin Doctor, though may not be quite as sleek and slender; I dunno.

Anyway, I think one-- man or woman-- can get very acceptable performance without having to go huge and bulky (which is not to knock the Road Morph's other fine attributes), particularly for only irregular use.

In all the years I've been riding, I've never used both CO2 cartridges. If I had to use three and only had two, out would come the credit card for a cab ride or a phone call for a pick up.

I'm not familiar with the dimensions of a 'tool roll,' or really what the limitation might otherwise be; what are we talking about here?

Also, a 700x38 ain't small; is this pump just for decoration, or do you need it to fill a flat in a reasonable amount of time and with a reasonable amount of effort? Are you just needing it to top off periodically, and relying on CO2 on-road?

If you're expecting to fill from flat, you want volume, and may even want to consider abandoning the small size/tool roll prereq in favor of something like the oft mentioned Road Morph.

If you just want quick access to a pump for topping off and will use a floor pump or CO2 for flat filling, then a you want a high pressure pump.

I know all Lezynes have a reversible chuck for schrader, so no problem there; it just unscrews, flips around, and threads back on, so you only switch it once. The Pen Gauge hose has the same.

Crank Bros Sterling is auto selecting for presta/schrader, lever lock. Kenshibiker's suggested the tiny Topeak Micro Rocket CB, which is presta only. The others I don't know.

i just bought the Crank Brothers Sterling pump

silver one on the bottom right.

dual volume gimmick works great... very (not an ISO standard, i know) small.

I have had many hand pumps over the years and the Lezyne is by far my favorite. Love that the hose fits inside of the pump, making it very small and easy. I don't have the hose gauge yet, but think I will probably get one. the one I have is for road bikes, high pressure but less volume. For the larger tires the OP describes more of a mountain bike type might work best - more volume but less pressure.

Now, I am thinking of ditching it altogether in my tool roll (which I have yet to get, let's not go there ... ..., however, I did purchase the PoCampo Logan Trunk Bag ... haven't gotten to ride wth it yet, but it looks promising.) and taking it back or keeping it to use at home. For home, I currently have a Serfas floor pump that I am considering selling as I have never used it.

Anway, any suggestions on a smaller/thinner mini pump?

Thanks!
Look, I personally I always prefer a pump over CO2 -
1. No risk of screwing up threading the cartridge on and losing everything, or getting a bad cartridge.
2. When I had little money, it cost less.
3. No risk of forgetting to replace a spent CO2 cartridge and ending up with nothing when I got a flat.
4. No risk of running out of CO2 cartridges from multiple flats (a lot of times they seem to all come at once)
5. Don't need to use up a cartridge to help someone else
6. Etc etc

All that being said though - an air pump in the size you are talking about is just plain terrible. Seriously they are just awful to use. A pump that small can barely get any air into your tire, and it's a pain in the ass.

I suggest you do one of two things -

1. Use a decent size mini pump, like a Road Morph Mini (that's the mini, not the regular full size version). It's bigger than you're asking for though. But I don't recommend anything smaller than that - anything smaller in a pump is just a pain in the ass to get a tire up to a decent pressure.

2. Use a combination CO2/air pump like this one (this is just a random one I found on amazon) -
http://www.amazon.com/RavX-Master-Mi...words=co2+pump

You'd have the air pump part as backup in case all your CO2 cartridges fail.

The bottom line is that tiny air pumps are a total pain in the ass to use, and why people use CO2. I recommend you either use a decent sized air pump (like the Road Morph Mini), or CO2 with an air pump backup built in.
