The role of a helmet is to keep a rider safe and, as a vital layer of protection against the hard unmoveable ground, finding one that is right for you and the type of riding you enjoy is imperative. 

The best mountain bike helmets are continually evolving, from retention to ventilation plus the addition and increased sophistication of rotational protection systems such as MIPS. These features increase rider comfort and safety so that you have a better time on the trail. It is also important to remember that even if your old helmet is still serving you well it may still need to be replaced. Helmets have a shelf life and while manufacturers provide their own advice it's generally accepted that a helmet should be replaced every 3-5 years based on use as the safety and integrity of the helmet degrades over time.

Luckily for you, Bike Perfect has been hunting down the deals so that you can replace your old faithful helmet with a new shiny head protector. Check out our pick of the best mountain bike helmet deals currently available or if you want to have a hunt for a cheap MTB helmet yourself we have put together a list of all the best places to find them.
