The Bike League's Smart Cycling program teaches the ABC Quick Check:
Air, Brakes Cranks & chain, QUICK release levers, CHECK shifting & function with a short ride.

I do this every morning before I get on my bike. I turn the pedals backwards, stopping every quarter-turn to give them a wiggle. I stand on the left side of the bike to do this so I might not notice if it was the right crank that was loose.

Does anyone know, would this routine detect a loose crank? Eden mentioned that there was no warning before her crank fell off. So that got me to wondering if I'm safe from this happening because of my ABC Quick Check habit.
