It almost goes without saying that if you ride off-road, it’s an extremely good idea to wear a helmet. Whatever genre of riding you enjoy, the odd crash is pretty much par for the course, and without a lid to protect your head and its precious contents, your trail riding career (along with your actual career) could well end up being a short one. When should you replace your bicycle helmet? Can you use a road bike helmet for mountain bike and gravel riding?
