Louis Garneau Course helmet



Cool, comfortable, easily adjusted helmet that the manufacturer claims to be the fastest of its kind.

At every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value – with value determined by how a product compares with items of similar spec, quality, and price.

What the scores mean

Good scores are more common than bad, because fortunately good products are more common than bad.

The Louis Garneau Course helmet might be pricy but it's very cool and comfortable, and the manufacturer claims it is the fastest aero road helmet out there.

We'll come back to those aero claims in a bit. The reason this has become one of my favourite bike helmets over the past few weeks is that it's very comfy. You get plenty of antimicrobial Xstatic XT2 padding inside, soft straps, and an easily adjustable fit system.

Louis Garneau call this their Spiderlock Pro II system and it features a polymer neck support – the bit that cradles the back of your head. You can alter how far this reaches by selecting the angle at which it attaches on the temples to the main body of the helmet. It's really easy to position comfortably and securely.

The small cam-lock dividers that sit below your ears are simple to set too, and once they're sorted you'll never have to think about them again. As usual, you cut the straps to the correct length once you have the fit organised, and melt the ends to stop them fraying.

Fine-tuning the tightness is a matter of turning a clicky dial at the back. It's a one-handed operation so it's easy to do while you're riding along.

One interesting feature is that you get a Spiderlock Vision light included in the box. It's a little waterproof LED that sticks to the adjustment dial via a hook and loop attachment. It's no substitute for a rear LED on your bike, but it's a useful extra with three different modes – one steady, two flashing. The battery lasts up to 80 hours and the whole thing weighs just 12g. Good idea!

The helmet is an in-mould construction with an internal frame within the expanded polystyrene (EPS). Other manufacturers use similar construction techniques, the idea being to enable the use of large vents without compromising the helmet's overall strength.

Louis Garneau reckon that their 'aero cage' optimises aerodynamics. They say that they've used Computational Fluid Dynamics (CFD) software to up the performance in two ways: to improve ventilation and to reduce drag.

The idea is that you get the highest air pressure at the front of the helmet, causing resistance. The Course is designed so that this air is pushed inside the helmet, channeled over your head and ejected out the back, reducing resistance as it cools you.

According to one of Louis Garneau's scenarios, a 70kg rider on a 9.1kg bike covers 40km in 53:20mins wearing a regular road helmet. In another (unnamed) road aero helmet (presumably for the same power output), the time drops to 51:22mins, and in the Louis Garneau helmet it drops to 50:40mins. Take a look at Louis Garneau's paper on the subject to see if you're convinced. 

Personally, I find that scale of difference hard to take and, until we win the Lottery, we don't have a wind tunnel to test the claims, so all we can do is report them rather than verify or disprove them.

I'd certainly say, though, that this is one of the cooler helmets I've used. There's very little material to stop the airflow to the front and top of your head. I'm not one of those people who normally gets an uncomfortably hot head during the summer – I'm happy wearing a helmet in any temperature – but even I have been pleased to have plenty of ventilation on the few 30°C+ days we've had recently. If you do suffer in the sun, this is certainly a helmet to check out.

Make and model: Louis Garneau Course Helmet

Size tested: Black Medium

Tell us what the product is for, and who it's aimed at. What do the manufacturers say about it? How does that compare to your own feelings about it?

Louis Garneau say:

* In-Mold Construction

* Super MSB technology: Ring-shaped plastic protection at the base of the helmet reinforces the perimeter for enhanced protection

* Integrated strap system with inner nerves: Inner frame which distributes the shock of impacts, this providing support and protection while being lightweight

* Evacuation channels: Moisture channels provide better airflow and moisture wicking

* Spiderlock PRO II: Helmet stabilizing system featuring a polymer neck support. It can be easily tightened on the head using only one hand, thanks to its dented anti-slip wheel. Its inclination can be adjusted to several positions

* Pro-lock divider: Small and light cam-locking device to quickly adjust strap position

* Wind-tunnel tested: The result is a helmet which follows the shape of the head without excess of material at the back, allowing better air evacuation, from the front helmet to the cyclist's back

* X-static XT2™ Padding: Quick-drying antimicrobial material that inhibits growth of odor-causing bacteria. Its ergonomic design gives you optimum comfort

* Spiderlock Vision light included: Whether you ride to work early in the morning or late at night, the back light will make sure you'll be seen

Not having a go at here, but the bike industry really needs to pull together some standardised aero testing soon. Whether is £160 on a helmet or £2k on a pair of wheels, selling them on the basis that they 'feel faster' without concrete evidence is crazy.

Selling them on that basis sounds like great business. Buying them, well, that's more open to debate, I'd suggest.

The head is a bigger source of drag than a bike's wheels, and that's confirmed in studies.

2 minutes 40 saving just by changing helmet? WhatEVER.

. . . if you're a half body mannequin on a bike going just over 40kmh?
