I can appreciate the aesthetics of hiding the pump in the seat tube, but the hassle of having to remove the seat post to access it really turns me off to the idea. Not to mention the pump would get all greasy...

WOW, rocket launchers and depth charges!

I'd only need to remove the seatpost to access the pump if I've flatted on the road. At that point, I've already been hassled. I guess time will tell if it becomes the straw that breaks the camel's back. In general, I'm not too fussed with the extra time it takes. Knock on carbon fibre... I hope flatting doesn't become too regular an occurrence... It wasn't too frequent a problem when I was carrying CO2.


Although I've just started doing this, I'd imagine my pump might stay cleaner inside my seat-tube than if left hanging off the side of a bottle-cage... especially in some of the more inclimate riding conditions I'm used to.

Yes. Lezyne pumps easily to 100psi easily. I switched from CO2 because the Lezyne is as light as an inflator and a couple cartridges, you can inflate tires fast, and the air never runs out.

For the multitool, there are a lot of great small ones. I like the Park Tool MT-1. It's light, cheap, and does practically anything you need so long as you don't need a chain breaker.

I love the idea. But I'd be worried I'd hit something hard enough to knock the pump so it falls all the way down

pump in the seat post wow.. That would work on some of my bikes.. As for the spare spokes I never broke a mavic kryserium spoke... do people break those spokes often they seem beefy enough..

I highly recommend the Lezyne pumps and pump holder. I thought that the pump would vibrate against my frame, but it is perfectly quiet and I don't even notice it. Very happy with it.

I don't know if you've used the Ritchey CPR9 tool, but it's much better; a better array of tools (for the modern bike; no nuts), better placed so they're more versatile (think water bottle cage bolts) and easier to work with. And it weighs half as much!

The ability to keep the pump in the post depends on the ID of the post and how close it is to the barrel OD of the pump. The Lezynes have a rubber cap on either end and those serve to friction fit the pump well enough in my post. No bear in mind that I am running a 26.8mm OD post with an ID of around 22mm. The Lezyne is snug... so snug that it takes about 10 lbs of constant force to pull the pump out. I don't believe there is any danger of it falling out of my post. And even if it does, it'll just hit up against the spokes below it and stick out of the seat-tube when I pull the post out so there's no danger of me losing it inside the seat-tube.

Now I know most people are running larger diameter seat posts with probably thinner walls so they'll likely have a larger ID and thus the pump might not snug up inside the post as mine did. In that case the solution would be to create your own friction-fitting gasket. I'd recommend an old strip of inner tube wrapped around the pump barrel near the end of the seat post.

I've broken one once during a ride and it sucked... which is why I carry spares now. That said, I haven't broken one since. So maybe this is my way of warding off spoke breakages. It should be noted that I have also tried to cut down on the amount of curb-hopping I do on my road bike.

There are very cheap Chinese pumps that come with a water-bottle bracket. Just get one, keep the bracket, and toss the pump. Search eBay for bicycle pumps, rank by price, and look at those selling at around $2.50. Here's one that's current:
