Types of Mountain Bike Helmets

The helmet is an essential safety precaution in the sport of mountain biking. Unlike sports where helmets may be optional, mountain biking's unpredictable nature on rugged terrain make a helmet mandatory. Although most mountain biking helmets are very similar, there are some key distinctions among different types.

Identification

When one says the term "mountain bike helmet," an image is likely attached automatically. Chances are you're thinking of the traditional mountain bike helmet that straps around your chin. Modern helmets employ an aerodynamic design, with various venting slots cut along the sides. Most mountain bike helmets also have a tightening knob or lock on the back to provide adjustment for a more customized, snugger fit. Helmets usually employ a visor to block some sun as well. Individual design and prices for mountain bike helmets range greatly.

Types

Full-face helmets, similar to those used for motorcycle riding and motocross, are used for more demanding, dangerous styles of mountain biking like freeride and downhill. Unlike their motorcycle predecessors, mountain bike full face helmets don't usually have a visor over the eyes/face but are left open. They are often used in conjunction with goggles or sunglasses.

Function

Whether you're using a standard helmet or full-face helmet, the purpose is to protect your head from major injury, cuts and contusions. Head injuries can be devastating, and hazards such as rocks, roots, tree branches and tree trunks are everywhere in the off-road environment. Freeride and downhill mountain biking entail very high speeds and big jumps and drops, thereby making the risk for injury much greater. Increased impact and full face protection is deemed a necessity.

Expert Insight

There are several different standards used to certify the integrity of a mountain bike helmet. Standards are derived by the impact resistance, strap strength and coverage provided by a helmet. Standard mountain bike helmets do not differ from other bike helmets in this regard and need to meet a CPSC (Consumer Product Safety Commission) standard. Downhill, full-face helmets, on the other hand, should meet the more intense standard ASTM F 1952, which requires additional coverage and impact protection. The difference is reflected in the full-face design and stronger, more rugged helmets.

Considerations

Many areas that allow mountain biking require the use of a helmet. Lift-served resorts where mountain biking is permitted will not allow you to load without a helmet, and many patrolled parks and recreation areas have similar restrictions. A basic bike helmet can be purchased at any variety of bike shops, sports stores or online retailers, and entry-priced helmets are inexpensive. There's no reason not to purchase and wear a helmet.
