Chains tend to fall off when you hit bumps, you simply don't notice the chain touching the front derailleur. The most famous example of this was David Millar dropping his chain in the Tour de France prologue in 2003. He opted for a single front ring and no derailleur. The dropped chain cost him the stage win
