Not the leading cause of traumatic brain injury. The leading cause of head injury. Head injury usually refers to TBI, but is a broader category because it can involve damage to structures other than the brain, such as the scalp and skull. That's a big difference. A difference that can distinguish a minor from a major injury

The focus here is on cycling, but that's part of the argument; placing the risk of cycling out of context. Without context, speculation is worthless
