Chain reaction Cycles and CRC are trading names of Wiggle Ltd (In Administration) registered in the United Kingdom at 1000 Lakeside, Suite 310, Third Floor N E Wing, Portsmouth, Hampshire, PO6 3EN, 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.

Beneath the shell is a heavily channelled EPS (expanded polystyrene) core that offers far more ventilation than your usual aero lid. The large base vents at the temple also feature textured grippers to hold your glasses when you're not wearing them.

Conclusion

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 shell contributes to its 325g weight, but provides extra protection from accidental damage, while inside the padding is made from Merino wool for super-soft comfort. The 29 vents offer plenty of places not only for the air to come in, but also to store your sunglasses. 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. Super-Fit - A great helmet is so comfortable that once it’s on, it virtually disappears. Giro’s proprietary three-size Super Fit system is based on “human scale factors” data and over 20 years of crafting helmets for the best bike riders in the world. The result is pure Skull Hugging Luxury, a helmet that fits 98% of the world’s population, yet looks (and fits) like it was custom made just for you.

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.

With a Roc Loc 5 retention system at the rear, the Giro Foray is easy to adjust on the fly with a single hand. You also get height adjust offering an even better fit

Wind Tunnel Ventilation - Giro helmets are developed utilising their proprietary Wind Tunnel™ ventilation system, which combines active vents with internal exhaust channels that thrust cool, fresh air over and around the rider’s head while forcing heat and stale air out. This significant increase in air channelling makes a difference that riders will immediately feel and appreciate. 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. Giro helmets are developed utilizing our proprietary Wind Tunnel™ ventilation system. This elaborate design combines active vents in the helmet’s shell with exhaust channels inside the helmet that thrust fresh, cool air over and around the rider’s head while forcing heat and stale air out. It’s the most effective cooling system available, and a difference you can feel every time you ride. The Foray Helmet shares the sleek styling of Giro’s premium cycling helmet, the Synthe, with a light, slim design that offers impressive ventilation and superb head protection at an affordable price.
