At road.cc 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.

The Bontrager Quantum MIPS Helmet is a comfortable fit and features the latest helmet safety technology, but it's heavy and misses a few simple features.

At 330g in the medium size tested, the Quantum MIPS is a fairly portly beast – helmet weights of around 200g are commonplace now, and you can get a 240g MIPS helmet such as the Lazer Blade for roughly a tenner less than the Bontrager if you shop around (we liked the non-MIPS-but-MIPS-like Lazer Blade back in 2015). Although 90g might not sound like much, when it's on your head, for hours, that weight does make a difference to neck muscles, especially the further forward you lean, as the angle changes from vertical.

I certainly noticed the difference between the Bontrager Quantum and my go-to lid for the past four years, a C Originals weighing 270g.

It's not the MIPS technology making the Quantum heavy – a thin plastic liner inside the helmet that allows the outer shell to rotate slightly a few mm around your skull (more info here). Put simply, this is a bulky helmet, and bulk, when you don't have many vents, means weight.

As I tested the Quantum over the winter months in temperatures never above 10°C and always with a casquette or thermal cap, I didn't get to assess the cooling aspects of the internal channels. There are three, recessed to allow airflow from front to back and out an 'exhaust port'. There's an argument to be had that fewer holes in your helmet must mean more protection, but there's no hard data (as indeed there isn't for helmets in general, but let's not go there).

The Quantum is available in six colours, including this commuter-friendly high-vis yellow – even the straps. Annoyingly for an £80 helmet, Bontrager doesn't provide any way to tidy away the straps beyond a rubber band. Adjustment is a bit of a faff, too, as the strap is one piece, passing through a single loop at the rear. If you're needing to adjust the strap fit regularly to allow for headwear, this might become annoying.

Bontrager does provide a twist fit system that tightens the helmet. This works well, coming down just far enough to make a difference but not so far as to feel odd when bent over, looking up. When adjusted correctly, the overall fit was perfectly stable on me.

The peak is removable, with small black inserts filling the holes, if you want to swap fashion looks between off road and on.

Out on the road for two or three hours, I didn't feel the Quantum held me back any, but I could notice a bit of extra momentum up top, when swinging about at low speed, battling climbs. On an all-day or casual ride you might well come to regret the extra weight.

Overall, the Quantum does the job, staying put and offering a reasonable degree of flexibility in fit and use. But you can't get away from the fact that it's heavy compared with other offerings.

Verdict

An average helmet that, while doing the job and with the latest safety technology, fails to impress

If it were 100g lighter and came with a chinstrap wrap, it would be a 4-star product. But it isn't/doesn't, leaving it pretty average for the price.

That's certainly a 'fails to impress' face being pulled there.

Isn't this a helmet aimed at MTB trail riding though? Comparing it with road/XC helmets for weight and ventilation without acknowledging that seems a bit pointless.

Not from what I can see on the Bontrager website.  Some road and mtb helmets are identical apart from colour and a peak in the box. Tarmac, trees and rocks all seem to be fairly substantial things, so if you believe a helmet's gonna help you I can't see why a lighter 'road' helmet is particularly a better choicen at the expense of supposed protection.
