Your mountain bike helmet is the single most important thing you take with you on the trail. It doesn’t just help keep you safe, it helps keep you alive. If your helmet and hit the ground in a crash or doesn’t cover the lower back part of your head it’s time for a new helmet. Whether you get it from Chainline or somewhere else, please don’t gamble with a helmet. So long as you’re here, check out our selection of full face helmets for DH and Enduro racing and our half-shell helmets for the a balance between comfort and protection. Ride well and ride safe!
