The bare essentials for moi

Combo wrenches
Metric deep sockets
(Tubeless) Tire repair strings
Can of Fix a flat
Multi screwdriver
Vise grips
Wire cutters
Allen key set
Box cutter and Glock
(It's tough sometimes to decide whether to shoot down the street, or cut through the alley)
Length of wire
Spare bulbs - 1 each is fine
Large med bottle full of spare fuses, squirrel condoms, butt connectors, and such
Roll of black tape
Rain suit
Addidas fleece lined nylon sweats for cool nights
Baseball or Pork Pie Hat
(GQ may want to shoot me for the cover - don't want any pesky helmet hair ruining my GQ smooth like a m'fer thing)
Sunblock
Bungies
Length of thin nylon rope
The other pair of gloves (One is mesh, other is not)
Small flashlight
Matches
Rubber gloves
Rags
Thin cotton balaclava
Gore tex socks

I could lose some of the above, but there seems to be enough room between the tool & saddle bags to tote it all around.
