LTD T100 PURE AERO Helmet EKOI Racing Mirror Cat2 Black
Limited series EKOI PURE AERO T100 Edition
EKOI, official partner of the T100 Triathlon World Tour, unveils an exclusive PURE AERO helmet in T100 colors.
EKOI has engineered one of the fastest time-trial lids on the planet.
Developed for pure performance, the PURE AERO is the result of advanced aero simulations and extensive wind-tunnel testing.
Result: up to 13 watts saved at 50 km/h compared to market standards.
Designed for flat, fast courses where aero is everything, the PURE AERO is the ultimate weapon against the clock.
The plus of this helmet
ERGO-AERODYNAMIC OPTIMIZATION
The helmet’s shape blends into the top of the shoulders. Air accelerates sharply over the top of the helmet.
BENEFITS
6% reduction in aerodynamic drag.
13 WATTS saved at 50 km/h
COOLING EFFECT
The gap between the face and the visor channels a volume of air that generates cooling.
BENEFITS
The helmet keeps its aero qualities (no "hole") while delivering maximum ventilation.
INTEGRATED VISOR AND MAGNETIC BUCKLE
The helmet’s visor is integrated.
The magnetic buckle delivers an intuitive, ultra-quick one-handed closure.
BENEFITS
A secure transition and precious seconds saved.
Winning with the best triathletes on the planet
The PURE AERO has already proven its speed in racing. In Kona, Patrick Lange claimed his third Ironman world title while the event’s bike course record fell with Sam Laidlow. A few weeks later, Jelle Geens became a double Ironman 70.3 world champion in New Zealand and then in Spain.
The new TT benchmark for our pro riders
Since its first appearance at the 2024 Tour de France, the PURE AERO has been unanimously adopted by our pro team riders for time trials.
This season, it will be the TT helmet of the WorldTour teams NSN Cycling Team and Lotto-Intermarché.

S. 26/01/2026 Age: 35-44 Level: Advanced Convenient: Gravel, Road, TriathlonHelmet Customizable EKOI Racing PURE AERO Black MIRROR Cat2Good fit and very light
Was concerned that the helmet would be too small as it only comes in 2 sizes. Am normally a Large and this was a perfect fit.
The helmet is surprisingly light on the head. Magnetic clip is very nice for quick placement and removal. -
Stanley M. 14/07/2025 Age: 55-64 Level: Expert Convenient: RoadHelmet Customizable EKOI Racing PURE AERO Black MIRROR Cat2Great tt helmet
I time trial, competing in 1 to 2 races per week all over the UK from April through to October.
The design works well when the head is inline with the body and the back is flat. The helmet is wide and fits snugly to the shoulders improving airflow over the shoulders and back.
Comfortable fit and good visibility.
Used for races in 25‘C temperatures and felt comfortable.
Overall a big improvement on my Kask mistral apart from the carrying bag.

Jeffrey B. 02/07/2025 Age: 65+ Level: Advanced Convenient: TriathlonHelmet Customizable EKOI Racing PURE AERO Black MIRROR Cat2Good - information lacking
I'm generally happy with the helmet. Fit is generally good, but to be in the aero position tight to my back requires completely disregarding the owner manual's instructions about not adjusting it off your forehead. It required adjusting the rear straps substantially shorter and the front ones longer. The website does not say whether the small size has a smaller shell. If it does, then I wish I'd ordered that size. It has been all over the press that the current IM champion used a vented version. Was this from the factory or was it a non-safety tested modification? The helmet is hot, but not horrible. I like the black/orange color scheme as I'm using McLaren colors for my bike and motorcycle. I don't understand the "Note:" input above that was preselected at 5. Assuming it was a 5-star rating, I changed it to 3.
Hi Jeffrey
We invite you to contact the costumer service in order to find a solution
Best regards

Del Moral Redondo R. 27/06/2025 Age: 45-54 Level: Expert Convenient: Gravel, MTB, Road, Running, TriathlonHelmet Customizable EKOI Racing PURE AERO Black MIRROR Cat2Ekoi racing - top notch aero gains
Hi!
I raced for the first time with my new helmet EKOI Racing PURE AERO Black MIRROR this past weekend on a olympic distance triathlon in the US (Kinetik Multisports Colonial Beach 2025) and I can say I felt the difference!
True fact is that I can feel how the wind is displaced off of my shoulders. The air flows as if the helmet/head and the shoulder/body were a one piece of aerodynamic construction, like a bullet, if that makes sense.
I really could feel the advantage specially while going above 45-50k/h, which is not the majority of the time, but it definitely helped maintaining the speed longer.
Although it has no ventilation holes, the air flows inside the helmet really nicely and it helps with the temperature management.
The vision filed is crazy, it's so wide! You can be tucked in and still see everywhere without having to raise your head, which helps maintaining the aero position and being more efficient.
It handles very well when you turn around to look back or to the sides, it doesn't feel like there's more drag or that it's unstable. It also feels very light.
The magnetic strap system is great! You need to practice a little bit, but then it becomes easy, fast and secure.
I'm very pleased with the performance and it also looks really dope!
Although I'll give it a 5 stars because the main reason I bought it was to improve my bike split, I think a helmet like this one should come with a sturdy hard case. It will make the product a top notch choice, protecting it while traveling as well as extending the life of it.
I would definitely recommend it!

There's still snow on the ground here in the Yukon, but looking forward to using the helmet this summer. I've tried the helmet on and it's comfortable and visibility is excellent!
