Product Information

Air allows cool airflow to pass directly over your head, further enhancing the performance of vents and internal 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). 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. Allowing a constant flow of cooling air to permeate through the helmet, the ten featured wind tunnel vents prevent you from overheating in hot climates and when you're giving it your all and aiming for that podium finish. 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.

The peak of the helmet is far enough from the top of the glasses to prevent obstruction while the two ventilation holes double up as excellent ports to house the arms of your glasses.

Aerodynamics

The Mips system is designed to provide added safety for helmets in many accidents. For certain impacts, the Mips system can reduce harmful rotational motion that might otherwise be transferred to the user’s head. Mastering the art of airflow, Giro presents their teardrop designed Vanquish MIPS Helmet. Proving to be the pinnacle of road cycling helmet technology, this concisely designed helmet has gone through months of rigorous testing and development to hone in on a design that effectively shapes and manipulates airflow. Superior in aerodynamics, ventilation and comfort, this helmet is set to break records. 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. custom tune fit tension and fore-aft tilt of the helmet in seconds using a single hand. Super Fit™ Engineering The Vanquish MIPS 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 RocLoc Air 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."

Giro says its new Vanquish MIPS is the most aerodynamically efficient road helmet the company has produced to date – and nearly the best ventilated, too. 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. 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.However, in reality, these numbers mean very little. If any of us were able to ride a 40km time trial at 400w we wouldn’t be buying our own helmet rather wearing the brand that sponsors our pro team. 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’. helmets.

integrated with Mips Technology to enhance comfort and cooling power while providing an additional measure of One of the most technologically advanced road cycling helmets on the market, the Giro Vanquish MIPS Aero bike helmet is filled with features to streamline airflow for reduced drag and increased aero efficiency. TransformAir technology gives you that extra little nudge, while the RocLoc Air system works to add cooling power and maximise comfort. Tell us what the product is for, and who it's aimed at. What do the manufacturers say about it? How does that compare to your own feelings about it? The new Vivid shield by Zeiss is what most riders will see as the defining feature of the Vanquish. This magnetic shield makes the Vanquish even faster by streamlining airflow, and features an all new road-tuned Vivid™ lens that increases contrast and definition while keeping colors true-to-life.
