In a time trial or triathlon, every second counts. A good time trial helmet, also known as an aero helmet or TT helmet, helps you minimize air resistance and maximize your performance. These helmets are specifically designed for speed, efficiency, and optimal airflow, so you'll cross the finish line faster.
What is a time trial helmet?
A time trial helmet is an aerodynamically designed bicycle helmet used in time trials, triathlons, and other time trials. Unlike a standard road bike helmet , a time trial helmet:
- Elongated and streamlined in shape, often with an extended tail
- Designed to reduce air resistance
- Equipped with an integrated or detachable visor
- Less ventilated, because cooling is subordinate to aerodynamics
These helmets are developed in wind tunnels and focused on high-speed performance in a low, forward-leaning position.
Why choose an aero helmet?
If you ride competitively or aim for personal bests in a time trial or triathlon, an aero helmet offers an immediate advantage:
- Up to tens of seconds of time saved on a standard helmet over 40 km
- Lower air resistance, so more efficient cycling with the same effort
- Tight fit and integrated visor for optimal visibility and comfort
For longer races or warmer conditions, you can choose a helmet with smart ventilation without compromising aerodynamics.
Important features of a good time trial helmet
- Optimized in wind tunnels for minimal resistance
- Tight fit and adjustable adjustment system
- Removable or fixed visor with clear view and UV protection
- Suitable for TT position (time trial position)
- Lightweight materials for long-lasting comfort
Some models are also suitable for triathlon, with faster take-off and put-on options during transitions.
Popular time trial helmet brands
Some of the best-known and best-performing brands in the world of aero helmets include:
- Giro: with iconic models such as the Aerohead MIPS and Vanquish
-
KASK : known for the Bambino Pro, popular with professional cyclists
- POC: combines aerodynamics with a distinctive design and safety
- Lazer: with innovative models such as the Volante and Wasp Air
- MET: offers various time trial helmets with and without visors
-
Specialized : One of the most worn helmets in the professional peloton
Many of these brands offer a choice of models with MIPS technology, visor options, or different sizes for optimal fit.
Buying a time trial helmet? Here's what to look for:
- How is the fit and ventilation for your type of competition?
- Is the helmet compatible with your sunglasses or are you using the integrated visor?
- Do you mainly ride time trials or triathlons (where quick transitions are important)?
- Does the helmet have a good score in wind tunnel tests or real-world experience?
If you're looking for pure speed, choose a long-tail helmet. For more flexibility, there are also hybrid models that fall somewhere between a road helmet and a TT helmet.
