The primary job of a cycling helmet is to protect your head in the event of an incident. However, brands are constantly pushing forwards in their attempts to make them more lightweight, more aero and more comfortable.

You can pick up a basic, entry level helmet that will meet the safety requirements in the UK for around £50 quite comfortably. However, for the cutting edge in aerodynamics, the lightest lid on the block or the most breathable brainbox, prices will exceed £200. Which is where deals come in.

The Cycling Weekly tech team has tested all sorts of cycling helmets over the past few years, so we certainly know what represents a good investment. We scoured the interweb for the best deals out there, on helmets that we’d recommend ourselves.

With each product is a ‘Buy Now’ link. If you click on this then we may receive a small amount of money from the retailer when you purchase the item. This doesn’t affect the amount you pay.

Giro Aerohead MIPS helmet was £259.99, now from £190

Read more: Giro Aerohead MIPS review here

It might seem pricey, but the Giro Aerohead is actually the cheaper of two options – the Aerohead Ultimate carrying an RRP of £519.99. However, we’ve reviewed both models – standard here, and Ultimate here – and we found that though the Ultimate has some nice-to-have features, the plain old Aerohead did the job (even for Dan Bigham who wore it to win a hat trick of National Track titles).

The wind tunnel tested lid comes with an eye shield made by ZEISS Optics, with magnetic attachment so you can flip it up (rather than chuck it in a bush if it fogs up).

Prices vary per size, but everyone gets a discount…

Buy now: Bell Zephyr MIPS helmet from £85.99 (most colours £125.99) at Wiggle 

The Zephyr represented a major departure in style for Bell, and it went well, receiving a place in the Cycling Weekly Editor’s Choice awards.

There’s a clever ‘Float Fit Race’ retention system which aims to dramatically increase comfort, 18 wide vents, plus a handy sweat guide which prevents drips from getting in your eyes on long, hot climbs.
