I managed to snap the chain on my Cannondale twice within the space of about a week. I have no idea what the chain was, it came with the bike (which was second hand and built up with the cheapest, shittiest components imaginable). If it's happened once I'd guess it's more likely to happen again, time for a new chain if you've not bought one already! KMC are cheap and I've never had any problems with them.
