The only 4 reasons a chain should snap in normal usage.
I always carry a breaker and a short length of chain for longer rides but have never ever had to use them.
The only time I have snapped a chain was on a bike someone else put together. Trackstand for a minute at the corner of Theobalds and Grey's Inn, lights change, lean forward, snap chain, fall on floor. Glad it was the middle of the rush hour.
Poor installation, chain damage, excessive wear, Unipack.
