Points To Keep In Mind For Best Road Bike Helmets Under 100

When it comes to buying one of these helmets, you need to know which of the features you want more. Everything depends on user compatibility and preferences. Let us now go through various features that one should have on their helmets while selecting from this category.

Exterior & Interior

There is no second-guessing for this one. You need an in-mold construction which uses a polycarbonate shell on the outside and multi-density(thick) EPS foam pads on the inside. The polycarbonate material and EPS inner foam is the perfect combination of shock absorption when you fall off. It is lightweight, durable, and secure.

So far as the internals go, you should also look out for detachable liner pads so that you can wash the pads to keep it clean and fresh. This feature helps you keep the fungal smell away from your helmet.

Adjustability & Flexibility of Use

You would want your helmets to fit on to your head properly and cradle it from all sides. The Roc Loc system helps you in adjusting the vertical grip of your helmet over your head. That way, you can move the helmet up and down. Moreover, the rear adjustability knob is a common factor in almost all bike helmets from this category.

Your chin straps must be adjustable as well so that you can decide the tension of the bike helmet. Since we are talking about adjustability, having detachable visors is the right choice for this helmet. If you are going to ride within the city, you would rather not want to wear the visor anyway as it tends to guard your peripheral vision. But if you happen to have it on your helmet, it should be detachable, granting you the flexibility of using or not using it. By the way, visors protect your face if you happen to fall on your face because it takes the first hit.

Ventilation system

Road bike helmets are supposed to have larger vents to take full advantage of aerodynamics. A better ventilation system does not necessarily imply having a lot of vent points, although that is indeed one of the factors. The other part of the story is that there should be air channels which will guide the air out and work as an exhaust system.

A proper ventilation system regulates the internal temperatures and lets you enjoy the ride instead of sweating.

Safety Standards

MIPS technology ensures the protection of your head from all sides and angles. It seeks to protect your head from experiencing shocks from rotational and sideway falls, which is common on road bike accidents.

The CPSC or other internationally accepted safety standard protocol certificates are essential. These certifications guarantee you in a way that these products are tried and tested. Moreover, extra paddings and linings never hurt. They are very important to save you from medium to high force strikes.

Frequently Asked Questions

Is there any bike helmet that takes care of my sweating issues?

Most helmets from this category come with thick padding inside and large ventilation ports. Moreover, the Bell Formula bike helmet is one such product that does not let sweat drip down on your face while travelling.

What are the essential features of a road bike helmet?

It has to be lightweight, strong & durable, which goes without saying. It must have a higher amount of ventilation ports and air-channelling system. Road biking is mostly about speeds, so you need something which will aid you in gliding through the air faster. To help the ventilation ports, the design should be like a droplet for maximum advantage of aerodynamics. You may or may not have a visor, but all-round protection of the MIPS technology is a must.


The idea that you are not wearing a helmet because you don’t have a road bike helmet is wrong and based on ill-founded logic. Protecting your head should be the biggest criteria. The rest of the features are there for comfort and extra facilitation.

Hopefully, you will get yourself started with getting one of the helmets mentioned in this list of best road bike helmets under 100 since you are now apprised of all the pros and cons.

Wearing a helmet is not a matter of choice, but it is being a responsible citizen. We still don’t have enough protection while riding bikes on sharp corners. It will be better if you go slower in tricky corners.

More importantly, not wearing any helmet does not make you cool. Keep wearing helmets no matter which variant you have with yourself. As long as they are fitting, you should be wearing one.
