The Bontrager Ballista helmet is a new aero road option with very good ventilation that keeps your head cool and comfortable as you ride.

Bontrager says the Ballista has less drag than any other aero road helmet out there. The brand doesn't put a figure on its claims – there's no spiel about the Ballista saving you a certain amount of time over a given distance – but it says that the helmet outperforms the Specialized Evade, Louis Garneau Course and Giro Air Attack, according to measurements in the wind tunnel. The other brands might well contest that.

We can't test the Ballista's aerodynamic efficiency, unfortunately, so you can either take Bontrager's word for it, or reject the claims.

What I can tell you for sure is that the Ballista feels very cool in use. You get three very large vents up front and two more on the top of the helmet. These lead into deep channels in the EPS (expanded polystyrene) that run right over the top of your head and on to a series of exit ports at the back.

When you hit a fast descent you can feel cool air coming in at the front and moving over your head to keep you cool and dry – or, at least, cooler and drier than you would otherwise be. There are more airy standard helmets out there but the Ballista feels cool for an aero helmet.

Bontrager reckons that as well as being good for cooling, the design of the vents and channels reduces drag. The idea is that the air comes in the front, moves quickly over your head and then exits out the back efficiently, rather than the helmet simply catching air like a parachute and slowing you down.

The Ballista uses Bontrager's Headmaster II fit system which features a plastic cradle that attaches to the EPS at the temples and the rear. You get the choice of three different height positions at the back while a clicky wheel allows you to set the tension easily. You can fine-tune the fit one-handed while you're on the move. It's a very good design, similar in essentials to several others, that fits a wide variety of head shapes.

Bontrager's AgION padding is antimicrobial, which is good news for keeping nasty niffs at bay. I really like the fact that one section of padding goes right across your forehead so you don't find sweat dripping in your eyes unless you work really hard and saturate the fabric. That makes a big difference.

The straps are soft and lightweight rather than the thick, reluctant-to-bend variety, and the strap dividers lock down tightly when you set them to the right place.

The Ballista is a good weight too, ours hitting the road.cc Scales of Truth at 266g. That's not particularly light for a standard helmet – the Bontrager Velocis that we reviewed recently, for example, is 222g  but it's a decent weight for an aero option.

I'm not bothered about the difference that a few grams makes to speed, but a lighter helmet feels more comfortable. I certainly didn't feel that the Ballista's weight affected comfort, even towards the end of long rides.

In terms of looks, I'd say the Ballista is a medium ranker for an aero helmet. I guess it looks a bit Mekon, but you can make your own mind up on that. If this black version doesn't do it for you, it's also available in white/silver and visibility yellow.

One more important point: like other Bontrager helmets, the Ballista is backed by a crash replacement guarantee. That means you can claim a free replacement if it gets damaged in a crash within the first year of ownership.

£130 for a helmet might not sound cheap but it's only fair to compare the Ballista with other aero helmets, most of which are considerably more expensive.

It doesn't look as good as some non-aero lids. It looks a bit out of place if you're not racing.

Use this box to explain your score

This helmet is very good in terms of ventilation and comfort. It feels a lot like a standard, non-aero helmet in use, and the price, while fairly high if you take the whole helmet market, is low for an aero helmet. It's clearly either an 8 or a 9 overall; I'm going with a 9 because of the comfort.

Overall rating: 9/10

...just like lots of products 'look' like other products, but everything I've seen (haven't gotten to try one yet) suggests that the Ballista outperforms the Evade in addition to being a good bit less expensive.

Bontrager says its the fastest, but has provided no verifiable data to substantiate this, neither did this article.. vs. the myriad of other aero lids which have been available for some years.. many with OEM and independent data...

So assuming its "as" aero, the best thing about this lid is that its cheaper.... for hopefully similar performance.. and thats Great..

Wish they'd stop writing Bontrager 50 times on everything though..

Some independent comparative date here between the current aero crop, interesting but controversial

The most interesting part of that was at the bottom where the owners of the wind tunnel tell everyone that Bike Radars test was wrong and doesnt give accurate results...

I've owned one for about 3 months and unfortunately crashed at the start of the month.

Landed pretty much shoulder first (broken collarbone, yay) but the helmet did a great job. Cracked the shell and foam of the helmet but I barely felt the head impact and of course it saved me from sliding down the road on my face.

The venting works pretty well and it's cheaper than anything else I've found that fits me as well so I look forward to the replacement coming.
