Fuel Canister under downtube

[thesonofhans]

Hey,

I've seen many people strapping their white gas fuel bottles to their downtube near the BB.  Anyone strap an iso fuel canister there?  I'd be concerned of rocks being kicked up an potentially puncturing it which would cause a miniplosion.

I normally nestle a medium sized one in my pot, but am thinking of bringing a large one on my next trip as I'll be in the woods for a few weeks at a time.

Thoughts?  Suggestions?  Feedback?

Thanks!

My first thought is that I wouldn't want to carry a few weeks of fuel in isobutane unless you were used it very sparingly. When going weeks without services I've used wood burning stoves (a bushbuddy) and carried a 20g chimney alcohol stove and a small amount of alcohol fuel for when it is too much work to prep wood (after a couple days of rain). A liquid fuel stove would be my next choice for long term use.

If you did want to use isobutane canisters strapping it to the downtube shouldn't be too bad if you cover it in some sort of bag, especially if it has a bit of padding. This should protect it from kicked up stones and sticks. I'd be wary of obstacles that you could drop the bike onto (fallen trees etc). Even it it doesn't pierce you don't want to make the fuel bottle unusable if you have a long time period before you can get to services and not be able to eat the food you've packed.

I don't put all my eggs in one basket - always take two canisters in case of leaks.
And I find two smaller canisters easier to stow.

I have carried a fuel canister in a water bottle cage on my front forks. I use a bungee cord to hold it in place on rough terrain.  Works quite well.
