Common Questions

Why do mountain bike helmets have visors? Mountain bikers are more upright than cyclists on road bikes, so a visor can be used to protect from sun glare. Wind drag is of little worry as the biker is typically moving at a slower pace.

How to choose a mountain bike helmet? Helmets vary by cycling specialty - from mountain biking to road biking and beyond. Mountain biking alone has helmets for enduro, all-mountain, cross-country, dirt jumping, and downhill. Your needs depend on the type of riding you do, and you may even need multiple helmets for your different rides.

How to measure for a mountain bike helmet? Determine head circumference by taking a flexible tape measure and wrapping it around the widest part of your head (1" above eyebrows). Alternatively, wrap a string around your head and measure with a yardstick. Use this measurement to find the right size bike helmet.
