bottle cage/road pump thingy

[SadieKate]

Is there a pump that mounts to the water bottle braze-ons that works for MTB tires as well? I never use my water bottle cage on my mtb as the bottle gets sandy/dirty when I ride the trails; I use a Camelbak instead. I've got CO2 cartridges in case of a flat but would just as soon carry a pump. I'm relatively new to mtn biking and don't even know if there's a difference between road and mountain pumps, is there? Enlighten me!

Thanks!

On our mtn bikes where we are always wearing hydration packs, we have small pumps like a Crank Bros that fits in the hydration pack.

Pumps are different in that some pump to higher pressure than others (good for road), some carry more volume than others (good for mtb), and the diameters of each are different so the water bottle clip from one won't necessarily work with another.

If you choose one of the mini-mini pumps that will fit in your pack, make sure you choose a dual action or you'll be there until the sun rises the next morning.
