We've seen all kinds of things cause crashes at bike races over the years - dogs and selfie-taking spectators being just two - and now drones can be added to that list following a spectacular crash at a criterium in California.
Footage of the crash was shot by cyclist Kaito Clark, who was taking part in the Golden State Race in Sacramento.
His bar-mounted camera captured the moment the drone shattered into pieces after hitting some tree branches, part of it apparently becoming lodged in the front wheel of a fellow competitor, with the unfortunate rider catapulted over the handlebars moments later.
According to a thread on Reddit, the cyclist escaped without serious injury - although his front wheel and helmet were both destroyed in the crash, with the drone operator offering to replace them.
