Choosing the right size bicycle helmet is essential to be comfortable and adequately protected. There are usually several sizes for the same model, with the exception of recreational helmets, which offer only one or two sizes. It is a good idea to try a few before making your final choice, because not all helmets have the same shape from one brand to another.
Safety and price
The price of a helmet varies between $50 and $350 depending on its features. Since all helmets must comply with the same safety requirements, the price does not influence the protection offered by a helmet. A less expensive helmet is no less safe than a $300 helmet.
A more expensive helmet is generally better looking, lighter and better ventilated. The straps and cushions are more comfortable and sometimes have an antibacterial treatment to eliminate odors. In addition, the adjustment hoop allows for a customized fit for greater comfort.
The different types of helmets
Urban / Recreational
These are more affordable helmets, perfect for the recreational or occasional rider. Whether you ride a hybrid, a road bike, or a mountain bike, this range includes helmets for all styles, including more urban helmets with styles closer to the BMX look. Bell, Giro, Poc and Smith helmets offer great urban products.
Road / aero
Road bike helmets are generally lighter and better ventilated than recreational helmets. These helmets are less hot and weigh less on the head, which is especially appreciated on hot days.
Aerodynamic helmets are for road cyclists who want better aerodynamic performance at all times. These helmets sacrifice some ventilation in the name of performance. We recommend them for racers or more serious cyclists who like speed. Oakley, Bontrager, Mavic, and Kask helmets offer good products for the road.
Triathlon
Triathlon helmets offer even more radical shapes than aerodynamic road helmets. They are helmets to be used in racing, triathlon or time trial, because their ventilation is generally deficient and they have a higher weight.
Mountain
Mountain bike helmets often have a visor in the front to protect you from branches and sun, but also for style. In addition, the back of the helmet is usually lower to protect the back of the head in the event of a fall. There are also full face helmets for extreme styles, such as downhill and BMX racing. Smith, Giro, or Kask helmets offer good products for the mountains.
MIPS Technology
The MIPS technology, Multidirectional Impact Protection System, is a shell inside the helmet that allows a movement of 10 to 15mm during an impact. This movement prevents the transmission of all rotational speed to the head. MIPS is inspired by the brain, which can move in the skull thanks to the cerebral spinal fluid. This technology is gaining popularity and more and more major brands are offering MIPS versions of their popular helmets.
