Seat bag:
2 tire levers
1 80mm valve tube
1 average length valve tube
1 valve extender
1 gel (in case of bonk)
2 CO2 cartridges
multitool
sometimes cell phone (if I need the space in my pockets)

Pockets:
mini pump (dual pump / CO2)
chapstick w/ SPF
wallet w/ keys attached. Containing usual stuff, but at minimum:
ID, CC, cash, insurance card
FOOD: packets of Clif bloks. Maybe Clif bar for really long rides.

Bike:
2 bottles, with electrolyte water and/or Clif drink
Garmin Edge 305

Helmet:
I write my insurance, emergency contact, and medical info on the ID stickers inside my helmet.


I should probably keep a dose of my migraine meds in my seat bag as well. They come in individual pouches. Even so, I worry about crushing it (fast dissolve tablets), and those buggers are expensive.
