I was thinking I would create a thread that details what everyone carried on their rides. Whether it be short distance, mid range, or centuries, what gear do you carry when the unexpected occurs? I know I have a ton of ideas about what I want to carry, but I also don't want to be a rolling bike store either. In my bike patrol days, we always carried, at a minimum, 100oz water backpack (Camelbak, Osprey, etc) and as far as tools go it was a hand pump, chain, multi-tool, tire tools, and tubes.

So, what do you carry?
