A Complete Buying Guide for Mountain Bike Helmets
With the top 5 helmets now fresh in your mind, you might also be interested in the features we used to select them. The following features served as the criterion, which allowed us to make the decisions. If none of these helmets appeal to you, the following guide will give you all the information needed to find the right ones.
The first thing to consider is the fit of the helmet. If the helmet does not fit, you will be unable to use it. You must consider how the helmet sits, which means that the size becomes important. Additionally, you also need to consider the fit system, with many helmets having a Float Fit System and others being fixed.
- Fixed Fit: The fixed fit system is much harder to adjust and since it ergonomically molded to a specific size, you need to have the right size. It is also less likely to move around when you are moving.
- Float Fit: Those with a larger head might also enjoy the Float Fit System, which allows the helmet to float around your head. However, it can be set in fixed positions, but the system will accommodate different sizes.
You will notice that most helmets have been ergonomically molded around the shape of pre-existing heads. It makes it much easier to buy the helmet and you can be sure that it will comfortably fit. There are many fitting guidelines that you can follow. However, each brand will have its fitting guidelines to consider.
Not much is to be said about the ventilation, with each helmet having various ventilation holes. For more advanced helmets, you can open and close these ventilation holes. However, you will mostly be counting how many holes are available. As a rule of thumb, it is best to find large ventilation holes of about 15.
Padding and Comfort
Padding and comfort are two of the serious features that need to be considered. Many people might be susceptible to chaffing, which means that they could develop a rash. However, the inner lining is not only for ventilation but also for comfort. Additionally, you will need to look at if the helmet has a lining around the ears and the straps to ensure more comfort.
If your helmet fits and feels good on your head, the next most important step is to look at the safety features. A helmet is not simply a shell that comes around your head, it needs to have the right protection features to keep you safe. Fortunately, there are many tech features designed to offer the best overall protection.
MIPS: One of the top features is the Multi-Impact Protection System that can absorb shock from various sides of the helmet. It is a bit more expensive to incorporate but offers the best overall protection.
Shell Design: A full shell helmet offers more protection around the sides of the helmet. However, it is also heavier. Half shells are for recreational riders that don’t storm downhill roads.
Adjustments: Lastly, you want some adjustment features that enable you to adjust the helmet on the fly. It can help when you are on the road and have to remove visors.
The different types of visors can be considered, but most of them are straightforward. There are a few anomalies that will help to combat things like mosquitoes and bugs you might drive into if you are not careful.
When to Replace a Helmet
Most bicycle helmets can be a lifelong investment if you don’t ride often. However, the rule of thumb is to replace them every 5 to 10-years if you ride often. Many people believe that you simply replace a helmet once it runs out of the warranty. We believe it comes down to how long the safety features are usable.
