Give yourself an aerodynamic advantage with one of the latest aero helmets designed for all-out speed…

1. GIRO SELECTOR RRP £239.99

Giro Selector

Tested weight: 454g (size M)

wiggle.co.uk

It’s been around a few years, but the Selector is still a high-performing helmet. The low, flexible side panels not only make it easier to put on, but also create an enclosed, streamlined helmet that feels like it’s slicing through the air. Its vented visor allows in just the right amount of air to keep your head from baking, although it is one of the hottest here. Affected quite a lot by wind buffeting during our testing, it is also the heaviest helmet on test, however.

Score 3/5

2. KASK BAMBINO PRO RRP £299

TEST FAVOURITE

Kask Bambino Pro

Tested weight: 359g (size M)

scotbycycles.co.uk

The Kask not only exudes quality (leather chin strap, anyone?) but also matches the POC Cerebel for lightness. It’s a compact aero helmet that’s secure and comfortable, resistant to gusting sidewinds, and fast. The visor offers great peripheral vision. Venting is spoton for springtime, thanks to six small inlets at the front and four at the rear. Foam padding at the sides sits in front of the ears, cutting wind noise. This is the Ferrari of aero lids.

Score 4/5

3. LAZER WASP AIR RRP £249.99

Lazer Wasp Air

Tested weight: 420g (size M)

evanscycles.com

The Wasp’s click-wheel perfectly tunes the internal ‘Turnfit’ system to the shape of your head. It’s quiet and cool, and the visor can be moved forward to let a few cooling gusts in. This helmet was impressive for its lack of buffetting, even when sitting up – Lazer’s wind tunnel testing has led to the ‘lip’ on top, designed to smooth the airflow. Our one gripe is that its visor had an imperfection that gave us a proportion of vision that was out of focus.

Score 4/5

4. LOUIS GARNEAU P-09 RRP £175.99

Louis Garneau P-09

Tested weight: 377g (size M)

evanscycles.com

A lightweight helmet which resisted buffeting in strong winds and allowed a near-perfect junction between tail and rider’s back. However, the sides of the helmet only just about extend over your ears, so it does lack the all-enclosed feel of some TT helmets. A sizeable air inlet above the visor positively gulps in air, and there’s a large central exhaust at the rear. Fitment is small, but the flexible and extendible side panels allow a snug fit over the side of the head.

5. POC CEREBEL RRP £280

POC Cerebel

Tested weight: 359g (size M)

chainreactioncycles.com

Designed to work efficiently in all riding positions, not just in an aero crouch, the Cerebel is light while the clear, vented Zeiss visor offers good optical clarity as well as resisting misting. Three exhaust ports do a good job of spiriting hot air from your head, but things do get a bit noisy in there on windy days. The closure is easily set up, although adjustment of the fit around the crown is a little fiddly, the dial adjuster being right up inside the back of the helmet.

Score 4/5

6. SCOTT SPLIT RRP £204.98 (including optional visor)

SCOTT Split

Tested weight: 413g (size M)

wheelies.co.uk

The Split’s visor is usefully vented, and one of the deepest here, so stray gusts are deflected. If you’re long of nose, the bottom of the visor might dig into the bridge of it when you’re laid flat over your bike. Click-wheel adjustment of the fit is child’s play. It’s a snug fit, mind, so takes some effort to get on and off. It’s a relatively quiet helmet that, while not super-light, is very stable in use.
