Lastly, the colour I tested – matte Glacier – was not to my liking but the other five options are all quite appealing, especially the one Giro calls ‘Dazzle’. It was particularly noticeable when climbing. Even on short ascents of five minutes, I could feel the change in temperature, becoming noticeably more sweaty and uncomfortable.

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. 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 Giro Vanquish shapes the wind to work for you. Designed to manipulate airflow, a weight-saving in-mould process enabled Giro to optimise their design to be exceptionally aerodynamic and breathable. Strong, impact damping and light, the protective EPS foam liner is bonded to a four-piece polycarbonate shell that has been shaped and optimised with TransformAir technology and ten wind tunnel vents. Improving riding efficiency and shaving seconds off your personal bests, the TransformAir 'cliff' effectively manipulates airflow to reduce drag and improve aerodynamics.

The Giro Vanquish MIPS

Enhancing aero efficiency, the ZEISS Vivid Shield provides a full field of vision, while maintaining the helmet's fast and streamlined silhouette. Keeping the road sharp and in detail, this lens offers true to life colours whilst effectively increasing contrast for great clarity and road insight.

Wind Tunnel Ventilation 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!

Inside the Vanquish is an EPS liner with progressive layering, and our renowned RocLoc® Air system seamlessly integrated with MIPS Technology to enhance comfort and cooling power while providing an additional measure of protection. I’ve only been able to sample the new Giro Vanquish MIPS helmet on a single ride so far, although with 130km (81 miles) of distance, a substantial 1,200m (4,000ft) of climbing — nearly all of which came in a single ascent at the ride’s halfway point — and warm, humid temperatures that hovered around 29°C (84°F), there was still opportunity to get a good feel for how it would perform over a longer period. When you are riding fast the Giro Vanquish does this. When hovering around the 30kmh mark I could notice a constant stream of cool air passing through the helmet keeping me suitably cool. Let Giro shape the wind for you, whether you’re going for your base mileage or leading the front in an Ironman course, thanks to the Vanquish MIPS Aero Helmet.Without going to a wind tunnel and undergoing specific testing it's difficult to really quantify just how much faster the Vanquish is over an open style road helmet but I can say that I pulled up several Strava PRs on the first ride with the helmet (on segments I ride regularly). 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. 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.
