Product Information

There’s also the matter of the shield’s aesthetics: fast or not, the look certainly takes some getting used to, and it remains to be seen if the style becomes less radical-looking over time. Using a patented design that suspends the helmet just slightly off the top of the skull, Roc Loc 5 Air Mips allows cool airflow to pass directly over your head, further enhancing the performance of vents and internal channeling that exhaust heat out of the helmet. 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.

But even a few hours into a mid-July ride in Florida, we still didn’t feel the need to just let our head air out. The padding also has a luxurious feel to it and sits in the optimum place on the forehead, providing plenty of comfort and mopping up sweat. The MIPS system consists of a low-friction layer between the EPS lining and the padding with an elastic fixation.

The main engineer on the Giro Vanquish MIPS helmet project, Alex Szela, recorded his test notes directly on this mock-up.

At certain angles you can see right through the helmet, the idea being that air flows in, over the top of your head, and out. For certain impacts, the Mips system can reduce harmful rotational motion that might otherwise be transferred to the user’s head. By now Giro's latest aero road helmet, the Giro Vanquish MIPS, has been seen on the heads of many of Giro's sponsored riders including Mark Cavendish's Dimension Data team. Without the eye shield fitted it is said to be 5 seconds quicker than the Air Attack with an eye shield fitted.

The Synthe’s proven reputation at the pinnacle of the sport makes it a no-brainer for those looking for marginal gains. After spending many thousands of miles underneath an Air Attack, we can tell you there was some room for improvement. The colour I tested (Citron/white) didn't help as it gave the Vanquish the look of a very cheap safety helmet. The generous airflow across the back of the lens keeps it from fogging, but could also be bothersome to riders who wear contact lenses. For comparison, the Bontrager Ballista aero helmet that I reviewed a couple of years ago was 266g (very lightweight for an aero helmet).Riders these days are paying more attention to safety than ever before, and it’s refreshing to see that Giro hasn’t merely glossed over that aspect in developing the Vanquish MIPS. Lighting conditions that day ranged from bright sun to heavily overcast skies, and the standard grey tint was perfectly agreeable throughout.

The aerodynamic Eclipse Spherical is our most sophisticated, stylish, and lightweight aero road helmet, and it's crafted with Spherical Technology powered by Mips®, so you can ride with more comfort and an additional layer of protection. The underside of the Giro Vanquish MIPS helmet is completely encased by the polycarbonate shell, which bodes well for long-term wear-and-tear. This fusion process allows for an improved ventilation system; as a result, In-Mold helmets are more lightweight and cooler than most traditional helmets.

Given that Giro started the aero road revolution back in 2012 with the Air Attack helmet, any launch from the American brand should warrant attention. It comes in one universal size, and uses the Roc Loc Sport MIPS adjustment system to help you achieve the fit you need. Fused with the MIPS system, Giro has ensured that their lightweight and sleek helmet provides all-around protection that meets and exceeds stringent safety standards.

With the new Eclipse Spherical, Giro claims the helmet beats the (undisclosed) ‘closest aero road helmet competitor’ by 14 seconds over 100 miles (160km), riding at 25mph, and is a full 60 seconds faster than the Vanquish. Giro mentioned that this is a maintenance issue; but they don’t explain how to dry up the sweat that rust the magnet within the helmet shell! 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. The outer shell is also integrated smoothly into the EPS core to complete a smart and classy aesthetic, although anyone wanting a hi-vis colour scheme will be disappointed by the more muted options of the Ano Blue seen here, plus black and red, charcoal, black and white options.
