All Giro helmets are designed to reduce as much energy as possible while meeting and exceeding stringent safety

helmets. By creating helmet molds in up to 4 adult sizes to match the human body's form, our Super Fit sizes The Aether follows very much a form-over-function approach in terms of aesthetics, with shatterproof, transparent arches running perpendicular to the venting slats for improved structural integrity and visual clout. You would get lower drag by switching to the Aerohead Ultimate MIPS, according to Giro, but that's a time trial helmet with an extended tail. So whenever you're making your last sprint to the finish line, want to ride a time trial or triathlon as fast as possible, or simply stay ahead of your friends during your weekly Sunday ride, you'll love having the Giro Vanquish MIPS helmet on your head!Giro's Vanquish MIPS is a well-designed aero road helmet with a great fit system, and it comes with innovative new technology designed to reduce drag. Giro's rigorous testing and development result in a helmet design aerodynamically superior to, and unmatched by, competitors.

True to claims, ventilation performance seemed better with the shield in place than stowed, too (perhaps due to the fact that doing so partially obscures the forward-facing vents). Designed to deliver greater depth and contrast to your vision, the removable Zeiss-developed lens can be stowed away by flipping it upside down or ditched entirely for regular shades, it’s your choice. As well as the helmet’s aero claims, Giro’s own cooling efficiency testing places the Eclipse at 89.25 per cent, half a percentage point behind the 21 vents of the more climbing-focused Aether, and ahead of its own Helios (87.68 per cent) and Vanquish (85.13 per cent) helmets. Metropolis International Group Limited, 10th Floor, Southern House, Wellesley Grove, Croydon, CR0 1XG. When Giro officially launched the Eclipse Spherical, it made a big play of the helmet’s aerodynamic and ventilation credentials.

We’re unable to verify Giro’s claims, but 25mph is nearly twice as fast as I’d ride 160km. However, there is the argument – put forward by aerodynamicist Dan Bigham and others – that aerodynamics matter to slower cyclists at lower speeds even more, due to the extended duration out on the asphalt. Joe was Cyclist's man for niche facts about Leif Hoste, anecdotes on how good Zdenek Stybar smells and the Cyclist Magazine Podcast, which he co-founded in 2020 with deputy editor James Spender. If the eye shield is a bit full-on for a Sunday group ride you can, of course, use the Vanquish MIPS with regular glasses. The vents are specifically designed to double up as eyewear ports and I've found them to work well with a couple of different pairs of Oakleys, for example. The Giro Vanquish MIPS Aero Bike Helmet is the pinnacle of high-performance road cycling helmets, featuring the innovative TransformAir design that actively streamlines airflow to reduce drag. Inside the Vanquish is an EPS liner with progressive layering, and our renowned RocLocAir system seamlessly integrated with MIPS Technology to enhance comfort and cooling power while providing an additional measure of protection. So whether you’re hammering off the front, smashing an Ironman course, or laying down maximum wattage in the dash to the finish line, the Vanquish shapes the wind to work for you. Key Features:
