For most of my rides; spare tube, patch kit, co2 canister and a frame pump. I rarely know where I will be going, or for how long, when I ride. There is a lot of cell phone dead area where I live. I lighten up when/if I know I am going for a quick and/or fast ride. I do not have one of my bikes set up for just that purpose, I like to switch rides regardless of what kind of ride I am going to do.
