Next time you go to the doctor or dentist, ask for a bunch of disposable gloves. If you need to fix anything on the trail, you will probably be a mess when you are done. I also carry some paper towels in a plastic bag in my tool kit.

You will not be in Outer Mongolia, bring what is appropriate.

Last trip, I brought:
- multi-tool that had almost everything (Alien II - Topeak).
- smaller multitool that is handy in the handlebar bag for 80 percent of what I would need.
- cassette removal tool and the adjustable wrench that goes on it, but left the heavy and large chainwhip at home thinking that if I needed to use it, I would destroy a nylon camping strap instead of carrying the heavy chainwhip.
- I have two rack bolts that my multi-tool can't reach, allen wrench for those two bolts.
- spoke wrench.
- smallest vice grip.
- tire pump.
- tire pressure gauge.
- tubes and a spare tire. Also carry tyvek from shipping envelopes to serve as emergency tire boot.
- tire levers.
- spare spokes.
- spare bolts and nuts.
- whipping cord, it is waxed polyester and I can lash almost anything together with that. (Sold at marine stores.)
- tiny container of oil.
- rear brake and rear derailleur cables.
- small roll of electrical tape.
- tools that I always carry for camping, such as swiss army knife, leatherman wave or similar kershaw pliers, tools to rebuild my stove or fix a tentpole.

Did not bring:
- cone wrenches or anything to rebuild a hub.
- bottom bracket wrench.
- crank removal tool with 8mm allen wrench. (I can't remember, I might have brought it only because I recently changed a chainring and wanted to be able to fix anything that I recently worked on?)
- tool for chainring nuts.
- cable cutters.
- other spares, the sky is the limit.

If I was going to Outer Mongolia, I would bring a lot more including a spare pump.
