If you’re a mountain biker you probably like to go the full length and nerve-wrecking jumps, techy trails and the most adventurous drops are what you’re after. If a sign saying "Danger! No Entry" isn’t a warning to you but rather a promise of unforgettable fun, be sure to wear a mountain biking helmet. On difficult terrain, a cool helmet is not only a statement, it also makes sure you, or rather your skull, make it home in one piece. Besides all-mountain helmets, there are also downhill helmets or enduro helmets. Want to know the differences?
