Giro Unisex's Aerohead MIPS Aero/tri Helmet

First time I wore this is was very self conscious as it’s a pointy go fast hat. However once settled down into the TT bike it feels secure, comfortable and - as all the reviews will tell you - it is fast. Good ventilation though I do always sweat down the visor no matter what helmet I wear. Visor clips very solidly in place with no rattle and stores upwards very well too. Easy adjustment with the standard giro dial behind the head. MIPS is an added bonus that doesn’t take away from comfort at all.

Very good quality. Worth the moneys Fits as advertised.

Zuerst mal zum Helm, Der ist wirklich Weltklasse! Passt mir in M perfekt (58cm Kopfumfang). Sieht toll aus, ist sehr leicht und angenehm zu tragen. Versand durch Amazon. Samstag bestellt, Montag geliefert! PERFEKT! Und nun zum negativen. Der Helm wurde mir ohne Zubehör und ohne original Schachtel zu geschickt. Es fehlt die Beschreibung, Visier und der Beutel. Der Helm war nur in einem Plastiksack verpackt, in einen zu kleine Amazon Karton gesteckt. Und dieser dann nochmal in einen grossen Karton. Und so sollte kein 235€ Helm geliefert werden. Update: Amazon hat sofort einen neuen verschickt der 2 Tage später ankam! Perfekter Service! Diesmal mit kompletten Zubehör, der Helm sieht richtig gut aus!

Fantastic helmet fits so well and really comfortable. Use for races in hot countries and the ventilation is great. Also having the visor come off and clip to helmet is easy to use when riding

The Giro Aerohead MIPS is a superb bicycle helmet. By two orders of magnitude the best I've ever owned. It's light and fits extremely well. I hardly notice it being on my head; the main noticeable effect with the visor down is great eye protection. There's no drying of one's eyes from the cycling wind. The Aerohead is cool. I rode with it yday and today in 90 degree sunny weather and never felt hot. The airflow system works. Presumably, the Aerohead is indeed aerodynamic. Any objective exploration of aerodynamics in real-world conditions is an exercise fraught with complexity. Still. I ride a 2016 Lightning Phantom and a very much older P38/F40. So, SWB's with relatively upright seating position. I measured 0.5-1mph faster than usual on the Phantom on a known trail, on two consecutive rides. My P38/F40 aluminum seat is at a fabricator's for welding repairs of cracks. I will definitely try the Aerohead on the fully faired F40 as soon as I get the seat back; I expect its effects to be remarkable. (Keep in mind what 1mph really means. Air drag increases with the square of one's speed, and the power to overcome air drag increases with the CUBE of one's speed. For example, 22mph takes 15% more power than 21mph, for the same machine and rider. Conversely, one can decrease drag and go faster for the same watts output.) The visor feature on the Aerohead is a great idea. I've mostly ridden with it down over my eyes, with sunglasses on underneath. Yet more surface area protected from skin cancer! Yet the visor can be attached, via its very powerful magnets, to the helmet leaving one's face exposed. Might be cooler in extreme heat, and certainly useful if dusk descends towards the end of one's ride. This little beastie also looks RAD. Especially in white. Sort of a cross between an Imperial Storm Trooper helmet and a Ford Motor Company American Helmet Model No. 8. You may have to Google that last one ...
