Mountain Biking - Newb needing advice.....

Hey guys, just picked up a new Camelback mule this weekend. Im trying to figure out what all to put in the thing.. i seen the other thread on here that is similiar and is helping out nicely.

my question is this,, i have tubeless Hutchinson Pythons. If i get a flat, what should i do? in other words, what do i need to take with me in my camelback to help me? Plus, what are those C02 cartridges for? and if i get a broken chain, do i just need one of those chain tools to put it back together, or do i need an extra link? thanks.....

When I'm riding my mtn bike with a camelback I like to keep a couple of tire levers, a multi tool, 2 spare tubes, you can carry CO2, but I don't think you need them with a mtn bike tire, I have a frame mounted pump which kicks azz on mtn bike tires. I also keep a cell phone, keys and some spare $ in it. That usually suits me fine. I'm sure I've carried more but that is all i can think of right now.

As far as you using tubeless, I'm sure someone will jump in and give u advice there.

Here is a link of multi tools at SuperGo. I would buy one at your LBS as they all have them in stock.

If you are riding tubeless and you flat, install a tube!

CO2 cartriges are used in special pumps for fast inflation of a tube. I find them of more benefit in road tubes than mountain tubes, though opinions may differ. For road tires, high pressure is critical and I normally need to get going in a hurry (usually I'll inflate the tube with a hand pump for a bit, then use the CO2 to get it to high pressure quickly). I find I can inflate a mountain tube to my usual 40-45 lbs pretty easily with a good mini-pump on the odd occasion that I flat.

Ditto to Hunter's advice: if you get a flat on a tubeless, use a tube until you get home and can repair and reinflate the tire properly.

i use co2 when i race so i can inflate tubes quickly. on normal rides i don't really care that much and just use my hand pump for a while.

tubeless tires, i would suggest you use stans. i've been running tubless for the last year and have pulled thorns out without a flat. maybe i'm just lucky but my luck has yet to run out:D

Hmm.... the CO2 cartridges are sometimes needed to seat tubeless tires on the rim. It's practically impossible to do with a mini pump, much less a floor pump even. You can patch tubeless tires just like you can a regular tire, you just patch the tire itself from what I understand. But honestly, I've never gotten a flat running tubeless, and I've been running it nearly a year now I think. I also run Stan's Tubeless fluid www.notubes.com which is just a latex liquid that seals punctures.
