Here is my kit in a tool roll from Harbor Freight.
From left to right:
1) 10 feet of rope- got the idea from Large Filipino, you never know when you will have to suspend either end of your bike in the air (great idea Large).
2) Electrical tape- to make it easier to travel, it is wrapped on a 1" wide piece of aluminum- 10 to 12 feet, very compact.
3) Zip ties- long ones, you can make a long one short, doesn't work the other way.
4) Tire gauge, tube patches and valve tool.
5) Tire removal tools.
6) Small slip joint pliers.
7) Small vise grips (any number of uses).
8) Cresent wrench.
9) through 13) Combination wrenches (more sizes, less space), 14-15, 9/16-5/8, 12-13, 10-11, 8-9
Second row- on the belt, not in the roll:
14) Leatherman- don't get a cheap imitation. They are well worth the price and work well. A cheap one will convince you combination tools are worthless. They are not, but the cheap ones are useless.
15) Cell phone
Then you can see where the roll goes- attached with three mini bungees.
Also, in the hollow area at the back of the "tank", a spare tube is bungeed to the frame in there.
Lastly, I have a frame pump mounted to mimic a manual oil pump shown in pic 3.
