What types of lubrication should I use for general maintenance for my bike? I'd like to avoid buying a bunch of different types if possible. I'm pretty sure after all the handling of my chain during installation that it needs to be touched up soon. I used a basic bike oil (really watery and thin) and poured it down the clutch cable (and thanks to your all's earlier suggestions it's much easier to pull now). Anywhere else, aside from the bike itself, I should keep an eye on?
