Best Aero Helmet Buying Guide

Finding the best aero helmet for you shouldn’t be a headache. Since the first order of business is for a helmet to provide a protective barrier between your head and any object it may come in contact with should a crash occur, all helmets are manufactured to pass safety standards, or they don’t reach the market.

Knowing that the choice for the best aero helmet will depend on your personal preferences. For instance, do you need a high-end helmet for professional competition or a cheap aero helmet for casual biking?

Aerodynamic Design

If you’re hoping to whittle a few seconds off of your time, then, of course, you’ll be looking for the fastest design. It’s always good to consult with a professional for the best design for you, based on the position which you race.

For instance, do you hunker way down, head first, or not so much? Your racing position can play a huge part in the style of helmet to use when it comes to slicing through the wind.

It is also a good idea to look for a helmet that has been wind tunnel tested. Also, the more vents a helmet has can reduce the aerodynamic effect, if so, some riders simply tape them over during competitions.

Fit

To find the best aero helmet for you, getting the fit is all important. In general, you’ll be wanting a helmet that is snug and not tight. A helmet that puts stress on your heads’ pressure points is definitely not a good purchase.

These helmets come with inside padding to help absorb sweat and give you a comfortable ride, so adjust the padding itself to improve the fit.

When considering fit, think of your hair length, do you ride with a ponytail, or will you be doing riding in a cold climate where you’ll require a winter hat under the helmet.

Retention System

This refers to how the helmet stays in place while you ride. Try to find a retention system that is easy to adjust. If you want to enhance your fit, look for a helmet that has a retention system which can be adjusted vertically.

Weight

If you are a weekend warrior, casual biker, then this should not be of much concern. However, if you are considering being competitive, the lightest helmet can be a huge plus in your favor on the track.

The lighter helmets are usually higher-end as it takes much design and quality materials to produce a durable, protective, lightweight helmet.

Final Words Regarding the Best Time Trial Helmet

Whether you are searching for the best cheap aero helmet for the weekends, or something built a bit more for racing, we are confident our review has assisted you in your quest.
