I regularly do all-day rides in the mountains carrying the following gear:

In my mini seat bag I carry a spare tube, CO2 pump w/3 cartridges, patch kit, tire levers, and sun screen.

In my jersey pockets, I carry a mini-tool, cell phone and cash, food (energy bars, bananas, etc.), jacket, arm warmers, leg warmers, camera, and pepper spray.

What else goes in the steamer trunk?
