When competing in triathlons or time trials, having the right equipment can make a big impact on your performance. Although the bike obviously plays the largest part in your result, an aerodynamic helmet can really make a difference when looking to shave off the seconds. Unlike the majority of standard road bike helmets, TT helmets are designed to optimise aerodynamics, making them significantly quicker than even an aero road helmet.

Why Choose a TT Helmet?

As mentioned, TT helmets (short for Time Trial helmets) are designed to minimise air resistance. Their streamlined shape helps to smooth the airflow over the rider’s head and back which reduces drag significantly compared to traditional road helmets, and can lead to substantial time savings during a race. Studies have shown that using a TT helmet can save approximately 8.5 watts at 25 mph, which translates to a time saving of around 49 seconds over an hour.

Comfort and Fit

While TT helmets are designed for speed, they also need to be comfortable and fit well to ensure optimal performance. Many models offer adjustable features, such as removable vents and visors, which can be tailored to the rider’s needs. Most of these helmets will also include ventilation to make sure riders don't get too hot whilst undergoing extreme efforts.

Comparing TT Helmets and Standard Road Helmets

Design Differences: Standard road helmets are designed with multiple vents to enhance airflow and keep the rider cool. Due to the large amount of cut-outs, they are usually lighter and more comfortable for long rides but lack the aerodynamic properties of TT helmets. In contrast, TT helmets have fewer vents and a more enclosed design, which can make them warmer but significantly reduces aerodynamic drag.

When to Use Each Helmet: Road helmets are ideal for the majority of most people's riding, offering a nice balance of comfort and protection. However, for races against the clock, such as Time Trials and Triathlons, a TT helmet is definitely beneficial and will certainly improve your performance.

Investing in a high-quality TT helmet can provide that competitive edge in triathlons and time trials, helping you achieve faster times and better overall performance. Above, you can find our triathlon bike helmet collection, all of which represent significant Watt savings over a traditional style rod bike helmet.
