My chain is falling off the back and that is sad
I have a Truvativ rouleur GXP crankset. Whenever I am in the small chain ring and the bigger rear cogs (like the biggest 4), the chain will fall off after a couple rotations of the crank. At first I thought it was the limit screws or maybe the way the front derailleur is positioned, but then I looked over it and they seem fine.
I think that the chainrings may be bent slightly. Are there any other possible causes?

Doesn't take a tool.
Take the chain off the rings and spin your crank while watching from a fixed point (I like pressing my head to the seat tube and looking down; it gives a stable reference).
If the chain rings are bent you will see them "wobble" while the crank spins. If they are not bent the rings will run true.
