Giro Foray Mips Road Helmet

Product Information

According to Lazer, it is also 2.3 per cent more aerodynamic than its predecessor, with a 12 per cent improvement in cooling efficiency. While it’s hard to verify the aero bonus, we could easily believe the cooling benefit – feeling a stream of air coming through the helmet top when riding.

The Z Alpha is less specific than some aero lids and all the better for it, with great ventilation and classy looks. You can opt to have MIPS or not, but a little extra outlay for enhanced head protection is a no-brainer in our book. Catlike Vacuum This lid's aero emphasis means ventilation is reduced to a single central vent, which is helped by internal channels that begin at the brow. In normal conditions it's very comfortable, with a constant flow of air across the head and no obvious hot spots, but it probably wouldn't be our first choice for a summer Alpine assault.With its sweeping, almost conventional shape, and 22 sizeable vents, the Z Alpha looks very open for an aero helmet. The snap-on front cover is said to provide the biggest aero gains at over 40kph. It only hides the central four vents, but has a slot to channel some air through. The ventilating aero mesh on either side of the silicone-edged sunglasses ports has been replaced by a finely ribbed plastic. The Giro logo and aero mesh covering the truncated tail's central port have gone too, and the only branding on the helmet is a single Rapha logo on the very top. The MIPS system, or Multi- Directional Impact Protection System, employs a slim, flexible plastic cap that's perforated to match the helmet's vents, and four elastic fixings allow it to float within the inner EPS foam shell, creating a slip-plane, much like the brain's own, to slow or reduce rotational energy transfer. Kask Protone Its MIPS system adds to the cost, but for that you are also getting great reassurance, and along with the super-adjustable Roc Loc 5 cradle is an excellent fit. Four internal pads keep things comfortable and five pronounced internal channels ventilate the majority of the head very well at all speeds, making this model an attractive, safe and great-value choice. Specialized has taken its ultra-aerodynamic S-Works Evade lid as the template for the Airnet, although it still has touches of the old leather ‘hairnet' helmets (hence the name) worn by racers from the 1970s.

Deep internal channels align with the large frontal vents to rush cooling air across your cranium, and the horizontal brow vents do a fine job of managing sweat and drying the front pad. It's very good for glasses storage when not wearing them too. Zero RH+ Z Alpha MIPS system can protect a user from all injuries and user assumes all risks, including all risks of bodily made by Mips. Warning: the Mips system in a helmet has been positioned in accordance with specifications

Clothing Size Guide

Every helmet on this list does just that, if not more, and should at least offer your head some protection against bumps and scratches if you fall off your bike while out riding. The Rivale's shape is more rounded than most aero helmets. The internal padding is minimal yet well placed, and the micro-adjust dial offers plenty of tensioning to keep it securely on your head. We especially loved the 4cm vertical adjustment in the retaining cradle, which enables you to situate it in just the right spot.

One note was the sizing: generally, I will wear a size small in helmets, but the Giro Syntax MIPS is on the cusp of being too small. Perhaps due to the addition of an XL to the range, the rest of the sizes have shifted downward a little compared to what I'm used to. As a result, I'd suggest anyone between sizes opt for the size up. Verdict

The Giro Syntax Mips helmet provides the safety of the MIPS system in a compact and low profile package

The 29 vents offer plenty of places not only for the air to come in, but also to store your sunglasses. It may have been around for a long time, but the Specialized S-Works Prevail helmet still delivers on all fronts: styling, comfort and ventilation are all superb. It manages to look both chunky and supremely vented at the same time, with muscular shaping and aggressive vents. There are 32 vents in total, ranging from large inline strip vents and boxy exhaust ports to small square vents that punctuate the diagonal arch architecture of the helmet and extensive internal channelling helps keeps fresh air flowing. Performance The Giro Foray is a sleek, stylish road cycling helmet that offer great value. The tough In-Mould polycarbonate shell to offers the best protection as you ride.

Internal channeling on the Tonic keeps air moving across the head, and probably reduces the weight a little, too. Ventilation is very good for a helmet at this price point — not as airy as something like the Prevail but much better than helmets in its class. Notably, the Velocis comes with a one-year crash replacement policy: if you crash it in the first year, you get a free replacement. The industry benchmark in comfort, stability, adjustability and weight savings. In addition to enhancing the fit and comfort of helmets, Roc Loc® 5 allows you to easily custom tune the fit tension and the fore-aft tilt of the helmet in seconds using a single hand. And it’s lighter than comparable systems too, making it the ultimate in skull-hugging luxury. that an individual who suffers a collision, fall, or other blow to the head while a person is wearing aThe fit should suit most head shapes, with the Mindset rear cradle offering plenty of vertical adjustment and the dial allowing you plenty of adjustability around the circumference of your head. Specialized S-Works Prevail MET's Rivale tips the scales at just 257g (for a large) and is said to save 3 Watts at 50kph, equating to a second's advantage over comparable vented helmets at the same pace. As well as that, it complies with CE, plus the tougher Australian AS and American USPC standards. At almost any speed and head angle there's a remarkable through-flow of air. It also comes with plugs (for winter rides or even faster aerodynamics) that go into the five frontal ports. The ARX Plus is particularly impressive at the front, where its large internal channels and a well-vented brow prevent the build up of sweat. Vertical adjustment may be limited to three press-studs offering 20mm of adjustability, but it proved perfectly adequate in practice. The small rear dial offers true micro-adjustment, which helps get a precise fit.
