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.What the road.cc scores mean
Good scores are more common than bad, because fortunately good products are more common than bad.
The Smith Signal MIPS helmet has apparently been 'built for the everyday rider', and while that might sound a bit vague, the styling seems surprisingly genre-fluid, working with technical and more casually themed clothing. Crucially, it has performed surprisingly well on and off-road.
The specification is pretty good, especially for the price point. There's the standard in-mould construction (where liner and shell are fused together simultaneously) and it's neatly executed. I always prefer shells that cover the EPS liner, but at this end of the market I wasn't surprised to find it exposed.
Its 21 vents are pretty good going for an 'everyday' design. Smith calls it its AirEvac system. Crudely, this is an 'inlet/exhaust' system: those at the front are designed to scoop cooling air inside, while warm air is expelled from the rear vents. It's also designed to prevent close-fitting eyewear from fogging.
There's also a slot for holding glasses when removed from your face – at a rest stop, say, or when mending a flat or rummaging through a pannier. Some LEDs will also mount through the rear vents – another definite plus.
More impressive for me is the MIPS (Multi-directional Impact Protection System) lining. This is designed to protect the brain from potentially damaging twisting forces experienced in a crash. A few years back it was the preserve of high-end models, but I'm pleased to see it becoming more prevalent at this end of the market.
The Smith also conforms to CPSC, CE EN1078, AS/NZS2063 standards.
Staying inside, we have the usual anti-bacterial pads and the 'VaporFit' system. This uses a dial, allowing it to be moved up/down/fore/aft to achieve optimal fit, regardless of head shape.
There are three sizes (51-55cm, 55-59 and 59-61cm), which should cater for most riders. The familiar buckle and strap system are equally intuitive to use.
I was initially conscious of the Signal's wider profile, but this vanished within a few minutes. Its 304g isn't feathery but I have a couple of racier designs around this weight, including the Giant Strive Mips Aero Road, so wasn't really aware of it, even on rides around the 40 to 50-mile mark.
February's milder side saw temperatures around 13°C in my far-flung corner of the South East. No call for a thermal skull cap, but even at 12mph I could feel a decent flow of cooling air through the follicles. Winding things up to a racier 20-odd, it kept pace with my own tempo but without becoming overly fierce. At the other extreme, winching up a long, torturous climb, I haven't had a clammy head, suggesting the exhaust vents perform on a par with others in my collection.
Some helmets can ram so much cooling air inside that they induce painful 'ice cream' headaches, even on very warm days. Descending at 30mph or so, the airflow remained uniformly good and without any annoying whistling or similar wind-noise that can impair conversation or even general road awareness.
It wasn't long before temperatures began tumbling to their seasonal norms, so back on with the Buff or fleece-lined skullcap, the adjustment wheel meaning you can tweak to accommodate these in a trice, mid-ride.
Given the seasonal temperatures I wasn't surprised to discover the pads remaining socially acceptable. I tend to take my lids into the shower with me, to subvert any funk and clean the outer shell. However, the pads here are easily whipped off and bunged in the machine should you prefer. Being gloss, the shell is easily spruced with a quick shot of furniture polish.
I have a Buff with integral peak, which comes in handy for shielding eyes from unexpectedly intense winter sun, dust and the like, but I was surprised to discover the Signal's brim also does a decent job of keeping things at bay.
Though closer to what I'd describe as a 'commu-tour' (commuting/touring) model, the Signal has performed rather well on my off-road exclusions, too, offering reasonable protection against brambles.
Its shape is also fairly conducive to mounting lights and lightweight cameras. I found my TomTom Bandit a touch on the weighty side but the Go-Pro (and its emulators) were a better bet.
Given the Mips system and overall specification, I reckon £69.99 is pretty good going.
Like for like, at this end of the market there's not much giving the Smith a run for your hard-earned. Bontrager's Quantum uses similar technology and seems well made, but the tester found its overall performance distinctly average. It's also a tenner more than the Smith.
Bell's Tempo Mips is the same price as the Smith and another decent 'do all' design. Admittedly, it's gender-specific (in name, anyway), but the range of sizes is refreshingly inclusive.
I've been pleasantly surprised by the Signal and, minor grumbles re the exposed rim aside, I reckon it's a good choice for general riding. It does most things very well and offers a decent spec for middling money.
Decent quality helmet for general riding with some nice touches, and reasonably priced

Generally well made, although I would have preferred the shell to extend around the rim.
Performs very well, especially for an "everyday" model. Ventilation is impressive, ensuring decent airflow and a temperate inner climate. Shape is very conducive to mounting action cams and some lights.
Seems well made and standing up to the typical accidental, everyday carelessness. However, I would have preferred the shell to encompass the rim.
Heavier than some road lids but very unobtrusive.
Unobtrusive, with very good airflow.
It's good value – there's not much at this price point meeting the Smith's specification.
Tell us how the product performed overall when used for its designed purpose
Well ventilated, it's very unobtrusive and feels comfortable for longer periods. Mounting lighting and other accessories is very straightforward. Anti-bacterial pads seem on a par with everyone else's and are easily washed, should the funk strike.
Tell us what you particularly liked about the product
Understated yet attractive design, good specification for the money.
Tell us what you particularly disliked about the product
Hardly a deal-breaker but it would be nice if the shell extended around the rim, protecting the EPS liner from everyday carelessness.
