best road bike helmets

Designed to protect riders from head injuries, brands are constantly competing to create the best road bike helmets. Factors like comfort, aerodynamics, and breathability are key opportunities for competition.

But how do you find the best road bike helmet for you?

Our guide will help you understand all the important aspects of buying the most suitable road bike helmet for you, including what to look for when purchasing and how to ensure you are getting the perfect road bike helmet in terms of fit, form, and comfort.

But first here's our top pick of the best road bike helmet for several different categories. 

Our pick of the best road bike helmets

For all cyclists, aerodynamics Vs weight and breathability will need to be balanced according to your priorities.

Weights listed are as reviewed - so may vary between sizes.

The ultimate road bike helmet

If you buy one road bike helmet, buy this. Here at Cycling Weekly we get to test lots of different helmets across lots of different categories, but if we had to pick just one, this would be our absolute favourite road bike helmet.

Giro Aether MIPS helmet

Giro Aether MIPS helmet

Best road bike helmet for all round riding.

Specifications
Safety features: MIPS
Sizes: S/M/L
Colours: 13
Weight: 269g (small)
Reasons to buy
+Very light weight+Super breathable+Really good looking+Lots of air channels give it a cooling effect
Reasons to avoid
-None!

An absolute favourite road bike helmet for us is the Giro Aether MIPS. On test we called it a game-changer of a road bike helmet due to its unrivalled all-around performance; it's exceptional ventilation ability, cutting edge safety features and all at an impressively low weight.

The Aether features MIPS Spherical technology, which sits between the two shells to make the added safety feature more comfortable. The lid itself is made up of six different pieces, attached in the middle, and there's the 'Aura' arch which extends across the top of the helmet for added reinforcement.

Its design not only provides exceptional safety in terms of onboard MIPS, but it also provides great ventilation and all in a sleek looking package.

The best helmets from each catagory

There are several different categories for road bike helmets, here's our top spot road bike helmets for each type of road cycling discipline, with handy links to swiftly navigate to see all our favourite helmets in each category.

Best aero road bike helmet

POC Ventral Spin helmet

(Image credit: POC)

POC Ventral Spin helmet

Best aero road bike helmet for watt saving without compromise

Specifications
Safety features: SPIN
Sizes: S/M/L
Colours: 12
Weight: 251g (medium)
Reasons to buy
+Tested aerodynamic qualities +Lightweight for an aero helmet +Breathable when covaried to other aero helmet options. 
Reasons to avoid
-Price tag is high

The POC Ventral SPIN could probably sit in a few of the best road bike helmet categories due to it's crossover credentials. 

Featuring large airports, the Ventral SPIN doesn't take the usual guise of a aero helmet, which tend to have a more solid appearance.

POC say that the unique design uses unique optimised CFD (computational fluid dynamic) testing which enhances aerodynamics performance by reducing drag and minimalizing air turbulence.

The aero lid uses POC's own SPIN (Shearing Pad INside) safety feature, a Design and Innovation Award winning protection which combines silicone bladders and pads for helping to dissipate rotation impact.

The fully wrapped EPS lid includes a handy eyewear garage, comes in a huge variety of twelve colours, including more conservative blacks and whites, and in three sizes which should fit heads measuring between 50cm - 62cm.

Best lightweight road bike helmet

Kask Protone Helmet

(Image credit: Kask)

Kask Protone

Best road bike helmet that's super Lightweight and cooling

Specifications
Safety features: WG11 Passed
Sizes: S/M/L
Colours: 11
Weight: 215g (medium)
Reasons to buy
+Super lightweight helmet+Breathable to help reduce head heat build up+Good aerodynamic properties considering it's design 
Reasons to avoid
-Colour options include matt or gloss, reducing the number avaliable

Weighing just an incredibly claimed 215g for a size medium, Kask say it's Protone has the lowest drag and fastest heat dissipation coefficients compared to other ventilated helmets on the market.

According to Kask, the design combination of several ventilation holes and a thick padding allows heat and moisture to be not only reduced, but swiftly wicked away for supreme comfort.

The Protone partners these lightweight and breathable credentials with a reinforced internal plastic sub-structure, which has been certified in passing the WG11 standard, a European testing standard on rotational impact, which is considered to have one of the most robust testing protocol standards.

It's on par price wise with the POC Ventral SPIN, and on paper looks to have a healthy colourway chart, but in practice this includes matt or gloss finishes and similar tones, so realistically reducing choice to more like eight.

Best time trial road bike helmet

Giro Aerohead MIPS helmet

(Image credit: Giro)

Giro Aerohead MIPS helmet

Best road bike helmet for speed without limitations

Specifications
Safety features: MIPS
Sizes: S/M/L
Colours: 6
Weight: 510g (Medium)
Reasons to buy
+Aerodynamic properties +Field of view is larger than expected+Comfortable fit when riding+Lighter than other options on market
Reasons to avoid
-Breathability isn't a huge strong point-Price tag is high

The wind-cheating silhouette of Giro's Aerohead will maximise your performance with its excellent aerodynamic design which also boosts plenty of ventilation with its four Wind Tunnel vents, although don't by any means expect it to be highly breathable. 

On test we actually used the even more aerodynamic Aerohead Ultimate, but with the same fit it is an almost like for like comparison, and are confident when saying this version is still one of the best road bike helmets in the time trial category.

It's rare to find a Time Trial/ Track helmet that not only which offers MIPS but also an impressive field of view, thanks to the wrap around eye shield made by ZEISS Optics. The shield is kept secure with a magnetic anchor attachment and it can also be stored in a flipped up position.

The weight, while looking rather hefty compared to standard helmets on the market, which is actually pretty reasonable for it's category. If it's really an issue, than the Ultimate version we tested is 30g lighter than this standard version. 

It's not cheap however, although when to discover that the version we tested is double the price it almost seems reasonable! Either way -  you've really got to want to get that PB on a bike.

Best Commuter road bike helmet

Livall BH60SE Smart Helmet

(Image credit: Livall)

Livall BH60SE Smart Helmet

Best road bike commuter helmet crammed with functionality

Specifications
Safety features: CE and EN1078
Sizes: One
Colours: One
Weight: 278g
Reasons to buy
+Reasonably light weight+Integrated SoS system +Built in lights, including breaking and indicating+Handsfree and windproof headphones and microphone+Connectivity with apps and phone+Good ventilation for riding in warm weather
Reasons to avoid
-One size option only-Phone battery/ signal demand requirement to use most functions

The Livall BH60SE Smart Helmet is mind-blowingly impressive.

From the interactive integrated lights to the automatic ICE calling system, it's actually so good that it's hard to place in just one category.

It somehow managing to cram everything from the SOS message system to playing your ultimate riding playlist, to super visibility in to one reasonably lightweight, good looking helmet for an impressive price.

Ideally it would have a MIPS crash protection and more sizes available. The only other to note is the impact on your phone battery, so not great for long distance riding.

Best women's specific helmet

Giro Seyen MIPS helmet

(Image credit: Giro)

Giro Seyen MIPS helmet

Best road bike women's helmet that incorporates form and function

Specifications
Safety features: MIPS
Sizes: S/M
Colours: 4
Weight: TBC
Reasons to buy
+Low profile design+Lots of cooling venting+Fit is really comfortable
Reasons to avoid
-Colours are limited-Sizing is restricted

The slimline helmet has been specifically designed to appeal to women's with its specifically stylised decals and colour choices.

Giro says this is because there are no anatomic differences between women's and men's heads except for the average diameter,  meaning the Seyen MIPS does not feature a unique women's fit.

The  lightweight women's helmet uses Giro's Wind Tunnel ventilation system, which combines a total of 25 active vents and exhaust channels to thrust cool air over the head and force the hot air out.

If you're after something a bit different, or wanting a more size subtle option this could be a winning road bike helmet for you. However, if you have anything bigger than a size 59cm head, and / or are after a more classic colour way, you'll need to look elsewhere.

Best Aero helmets

Aero helmets will be wind tunnel tested, and will often provide a watt-saving figure as to how much energy can be retained thanks to the improved aerodynamics of the helmet.

Abus Gamechanger helmet

(Image credit: Abus)

Abus Gamechanger helmet

Best aero road bike helmet for a lower cost option

Specifications
Safety features: ABUS Multishell
Sizes: S/M/L
Colours: 13
Weight: 265g (small)
Reasons to buy
+Comfortable fit +Aero optimised+Aesthetics are pleasing
Reasons to avoid
-Retention system not smooth-Coarse straps -No MIPS option

On test we were impressed by how competitive the ABUS Gamechanger helmet was compared to other Aero specific helmets.

It's not the lightest lid by any means, but weighing in at just 21g heavier than the nearly double the price Specialized Evade II (which also didn't feature MIPS) that's not bad going.

Riding the Abus GameChanger helmet over a combination of hot mountain climbs, indoor track races and even winter racing gave the ventilation system a good test. In the heat the venting proved great at preventing overheating, while the closed off vents were good protection on the wet days. 

As with any specific aero claims, they are tricky to prove out on the open road, but we can vouch for it's cooling system. The only negatives were the rough retention system, which could do with being smoother, and straps, which we found coarse, in line with more entry level helmets.

Lazer Century MIPS road helmet

(Image credit: Lazer)

Lazer Century MIPS road helmet

Best road bike helmet with extra innovative features

Specifications
Safety features: MIPS
Sizes: S/M/L
Colours: 4
Weight: 342g (large)
Reasons to buy
+Removeable panel+Built in rear light
Reasons to avoid
-Weight is more than other helmet options 

The Lazer Century MIPS helmet is the ideal road bike helmet for multitasking. It can swap between a both aero and vented camps, making it a two in one option, thanks to a removable magnetic panel at the front.

Although we don't have an exact wattage saving when the panel is in place, it's removal is said to increase airflow by 11 percent.

The built in rear light, with continuous or flashing modes is USB rechargeable, but a little fiddly to use and function do to the switch and charge port locations.

With MIPS on board, the Lazer Century MIP helmet provides peace as well as additional safety for your (and loved ones) minds, although there is a, slightly cheaper, non-MIPS version available if you'd prefer.

However, with all these bells and whistles comes a weight penalty, of probably less than 100g for an equivalent sized lid, which is something to consider when weighing up the pros and cons.  

best cycling helmets aero helmet

Kask Utopia road bike helmet

Best aero road bike helmet for cooling system

Specifications
Safety features: MIPS
Sizes: S/M/L
Colours: 8
Weight: 266g (Medium)
Reasons to buy
+Cooling system is excellent+Lightweight option+Low profile design+Aerodynamic properties +High level of adjustability
Reasons to avoid
-Firm and minimal padding can make it an uncomfortable fit for some-Pricey option

We found this to be one of the best road bike helmets on offer, and rated it so much that we gave it an Editor's Choice award. 

As see on Team Ineos, the Italian outfits latest aero lid is slippery in the wind tunnel yet won't leave you a sweaty mess making it the perfect road bike helmet for hard workers prone to perspiration.

Despite its closed off silhouette, the deep channelling and vents under the brow keep your noggin cool and your sunglasses free of sunscreen infused sweat. The down side to this effective channelling system is it's lack of padding. It was reasonably uncomfortable for the first 10minutes of each ride, but some how you can sort of dial in to the feel and it does become unnoticeable after that. 

It's not the lightest helmet out there, but at 266 grams it disappears on your head once you've strapped in on.

Bell z20 Aero MIPS helmet

(Image credit: Bell)

Bell z20 Aero MIPS helmet

Best aero road bike helmet for sweat wicking

Specifications
Safety features: MIPS
Sizes: S/M/L
Colours: 7
Weight: 252g (Small)
Reasons to buy
+Great sweat wicking system+Comfortable fit +Cooling effect when riding+Great level of breathability
Reasons to avoid
-Glasses port doesn't provide a firm hold-Coarse straps

Bell make the Z20 in a few guises – the standard Z20, Z20 Ghost and the Aero model. As you’d expect, this one is meant to cut through the air with minimal drag making it one of the first choice road bike helmet for anyone wanting to shave a few seconds off their sprint.

On test we found it a comfortable helmet with a well integrated MIPS layer, a great additional safety feature. There's plenty of breathability, and the brow pad sweat catching system is a good idea, especially for anyone prone to leaking on hot days in the saddle.

The only let downs were the material on the straps, which felt rough and cheap for a helmet at this price point, and the slightly temperamental glasses port, which wasn't really a port - just ventilation intakes which didn't hold sunglasses confidently. 

Weight wise, it's not too shabby, and certainly on a par with the Abus GameChanger (above) and lower than the Smith Ignite (below) for an equivalent sized model. 

Smith Ignite helmet

Smith Ignite helmet

Best aero road bike helmet enhanced safety features

Specifications
Safety features: Koryd & MIPS
Sizes: S/M/L
Colours: 5
Weight: 277g (Medium)
Reasons to buy
+Great safety features+Comfortable fit+Aesthetics stand out+Great aerodynamic properties
Reasons to avoid
-Tricky to keep clean

Comfortable, undoubtedly slippery through the air and packed to the rafters with the safety features of Koroyd and MIPS, making it one of the most advanced road bike helmets on the market.

It has Smith's VaporFit retention system which can be adjusted vertically and horizontally to allow for a snuggly fit for all head shapes, another rare feature especially in aero focused options.

Smith's Ignite should certainly be a first choice helmet for those riders looking for an aero advantage without the drawbacks, although the matt finish tends to look a little grubby quite quickly - so no chucking in the kit bag post ride if you want to keep it looking ship shape for as long as possible. 

Giro Vanquish helmet

Giro Vanquish helmet

Best road bike helmet for versatility

Specifications
Safety features: MIPS
Sizes: S/M/L
Colours: 5
Weight: 300g (Medium - without visor)
Reasons to buy
+Duel purpose road and Time Trial helmet+Comfortable fit+Enhanced airflow to keep cool+Clear visor optics+good safety features
Reasons to avoid
-Divisive looks

Giro created the Vanquish to find the perfect balance between a road specific and a wind-cheating TT aero lid, making it a great road bike helmet for riders looking for a do all option. 

The front of the shell features what the brand calls TransforAir which uses a small step to trick air into behaving as if the helmet had a full teardrop. If you're lining up for a TT or triathlon (gasp), an optional magnetic visor improves its wind-cheating prowess. On test, while we don't have lab like feedback, a handful of Strava PR's without any other equipment changes is a pretty good endorsment.

With decent-sized front vents and deep internal channels plenty of air is sucked through the helmet to prevent a sweaty head. Giro has opted to use the Roc Loc dial retention system found across the brands helmet range, and packaged with anti-microbacterial pads, it's a very comfortable helmet.

While there are lots of reasons why you would want the Giro Vanquish helmet, the biggest reason why you wouldn't are it's looks. Our tester felt that the shape and colour did the otherwise excellent helmet no favours whatsoever, as would probably see many riders reaching for the likes of the slightly less versatile Smith Ignite or TT specific Giro Aerohead. 

Best lightweight helmets

Lightweight helmets will save obviously save weight, and often mean breathability, something that will have more appeal in summer.

Giro Helios Spherical helmet

(Image credit: Giro)

Giro Helios Spherical

Best lightweight road bike all-rounder helmet

Specifications
Safety features: MIPS
Sizes: S/M/L
Colours: 5
Weight: 260g (Medium)
Reasons to buy
+Lightweight option+Comfortable fit+Aerodynamic properties+Aesthetically pleasing
Reasons to avoid
-No eyewear dock

The Giro Helios Spherical is a superb lid that does it all and, like the more expensive Giro Aether, integrates the latest safety tech without compromising comfort or weight.

There are loads of colours to choose from in the low-volume lid, in this MIPS-powered helmet, which integrates the sliding layer to present one of the best road bike helmets we've ever ridden, only just loosing out on top spot to it's sibling the Giro Aether MIPS helmet. 

It's technically aimed at the gravel and adventure riders, but more than happy on a tarmac-faring cyclists making it one of our favourite road bike helmets.

The only downside is that there's no specific eyewear port, although to be fair, with so many venting channels, you can more or less find an option to poke your sunglasses arms through. 

Lazer Blade+ MIPS Helmet

(Image credit: Lazer)

Lazer Blade+ MIPS Helmet

Best low-cost lightweight helmet

Specifications
Safety features: MIPS
Sizes: S/M/L
Colours: 6
Weight: TBC
Reasons to buy
+Lightweight option +Comfortable fit+Ventilated when riding
Reasons to avoid
-Retention system isn't the best

We highly rated the Lazer Blade helmet when we saw the non-MIPS version, so this new safety feature update is music to our ears.

While it does push the price up a little, this is still a really great price for head protection with what is considered the gold standard of safety features.

Good enough looks wise to compete with helmets much higher up the food chain, as well a providing great ventilation means that this is a great road bike helmet for anyone wanting an more affordable all rounder. 

The only thing that we do struggle with on the Lazer helmets in general is it's top barrel adjustment system that sits on top of the lid. It's effective enough, but we've found it doesn't quite offer the same accuracy as the Giro Roc-Loc system. 

Oakley ARO3 helmet

Oakley ARO3 helmet

Great budget friendly road bike helmet for weight Vs ventilation

Specifications
Safety features: MIPS
Sizes: S/M/L
Colours: 7
Weight: 254g (Small)
Reasons to buy
+Great ventilation +Comfortable fit+Breathable on hot days+Great looking option
Reasons to avoid
-Retention system-Lack of hair space

Despite it's aero looks, the Oakley ARO3 helmet is in fact designed to be a lightweight helmet with plenty of ventilation.

At 254g in a size small, this helmet is reasonable, although not as light as other competitors in the lightweight category, such as the Giro Helios Spherical, but probably the lightest entry level option.

On test we found it a comfortable helmet, although did lack a ponytail port. Offering  plenty of breathability for hot days in the saddle, we found the overall package really attractive.

The Boa dial retention system wasn't a winner for us, but it did its job as required and we'd more than happily recommend this helmet for those seeking a cool head under the hot summer's sun.

HJC Atara helmet

HJC Atara helmet

Ultra-light for the price

Specifications
Safety features: EPS
Sizes: S/M/L
Colours: 5
Weight: 204g (Small)
Reasons to buy
+great value option+Lightweight package+Breathable when riding
Reasons to avoid
-Sizing range limited-Safety features limited

At just 204g and around the entry level price point, the Atara is impressively lightweight, making it an excellent road bike helmet for anyone starting out on their cycling journey. 

There are a host of features you'd expect in a much higher end model, including wind tunnel testing, and a streamlined design making it great value road bike helmet for the money.

This helmet from HJC features eight vents plus a rear exhaust system, and we found the front vents to be really useful for holding a pair of cycling glasses.

We'd suggest trying before you buy as the recommendations on the size chart did not seem to match the fit - in our case, the small was too big. 

Our only concerns were the lack of safety features. In order to hit this competitive price point there's no MIPS or equivalent, which are found on the likes of the  Lazer Blade+ MIPS Helmet for not a lot more price wise. 

Lazer G1 Genesis helmet

Lazer G1 Genesis helmet

Lightweight but with option for aero cover

Specifications
Safety features: MIPS (higher spec version)
Sizes: S/M/L
Colours: 6
Weight: 205g (Medium) 247g (+aeroshell)
Reasons to buy
+Lightweight option+Comfortable fit+Secure feel when on
Reasons to avoid
-Requires aftermarket aeroshell to gain aero advantages. 

A featherlight and comfortable lid which felt secure when on and boasts a simple, stylish look. To fit to your individual head shape the rear barrel retention cradle has a large amount of vertical adjustment, but as with the Lazer Blade+ MIPS Helmet, this doesn't provide much in the way of horizontal adjustment, so not as fine tuneable as any of the Giro helmet offerings. 

That said, it's still a comfortable road bike helmet and one that is very lightweight, in-fact at 205g for a sized medium on our test scales, one of the lightest helmet we've seen. 

You do need to "shell" out for the additional after market aero layer, it's not a big outlay, and if you want to harness the helmets go faster properties, it's a minimal weight penalty, and would make it a really lightweight to aero specific road bike helmet too.

MET Vinci MIPS helmet

(Image credit: Future)

MET Vinci MIPS helmet

Great road bike helmet for 'trickle-down' tech

Specifications
Safety features: MIPS
Sizes: S/M/L
Colours: 5
Reasons to buy
+Lightweight helmet+Comfortable fit+Cool and aero when riding 
Reasons to avoid
-Sizing (we recommend sizing up)-No specific glasses port

The MET Vinci is a good looking lid which manages to expertly combine breathability and aerodynamics with lots of vents as well as watt saving promises.

The Vinci's design is clearly similar to the top end MET Trenta, although a little more boxy. It has 16 vents, which helps keep the helmet's heat build up down, and again much like the Trenta, the Vinci MIPs also has internal channels to help push air over the top of the head. Both features making it a cool option for hot days on the bike.

The are no specific glasses port, although the helmet design does allow for the venting holes to do a reasonable make do job. 

The retention system offers good adjustability, closer to the Giro Helios helmet, or any Giro helmet for that matter, but with a wallet friendly price tag. 

Unfortunately for our USA fam, the MET range still isn't available. Fingers crossed it will be more readily accessible again soon.

Specialized Evade II helmet

Specialized Evade II helmet

Best lightweight road bike helmet with excellent comfort

Specifications
Safety features: MIPS
Sizes: S/M/L
Colours: 5
Weight: 235g (small)
Reasons to buy
+Aero qualities+Very comfortable fit +Highly breathable +Integrated Specialized ANGi crash sensor+MIPS on board
Reasons to avoid
-Straps aren't very adjustable

Specialized's Evade aero helmet has always had a stand-out aesthetic, but the newest iterations claim to be six seconds faster over 40km thanks to revised aerodynamics. It's also more breathable and lighter by 12-20 grams when compared to previous versions - the small model comes in at only 235g which could easily earn it a place in the best lightweight helmet category.

There's a Gutter Action Brow Pad, to mop up sweat, and a handy HairPort for those with long locks.

The helmet now comes with Specialized's ANGi crash sensor mounted on the back of the Mindset retention system and MIPS making it one the best road bike helmets for safety features too. 

It's a good rival for the Giro Aether MIPS helmet, just slightly more expensive, so doesn't quite hit the top spot. 

Best time trial helmets

Time trial cycling helmets are similar to aero helmets in that they will be wind tunnel tested and have significant watt-saving data. Typically they will have a longer ‘tail’ than an aero helmet, and will focus solely on function.

Bear in mind that these are all about out and out speed from A to B so might not be suitable/ UCI or other governing body legal for anything other than time trailing events.

Met Codatronca helmet

Met Codatronca helmet

Best Time Trial Helmet for versatility on longer and rolling courses

Specifications
Safety features: CE; AS/NZS
Sizes: S/M/L
Colours: 2
Weight: 265g (small)
Reasons to buy
+Comfortable fit for a TT helmet+Great adjustability+Versatile for sporting courses
Reasons to avoid
-Visor doesn't provide the best vision. 

The Codatronca has a short tail which makes it a more versatile time trial helmet for most riders. Riders will still get significant aero gains but without having to worry that you are always in a perfect optimum "turtle" position - this is particularly relevant when faced with sporting courses.

We found it was a very comfortable lid, which provided a close fit with Met's 'Safe-T Orbital' fit system with retention dial. It also had sufficient ventilation thanks to its three small vents on the front and further two 'exhaust' holes at the rear - included to channel air out the back. It has a clever magnetic visor system, but bear in mind the visor is quite long and therefore may take some time to get used to.

The only downside is that Met helmets aren't currently available in or allowed to ship to the US.

Lazer Wasp Air helmet

Lazer Wasp Air helmet

Specifications
Safety features: CPSC
Sizes: S/M/L
Colours: 1
Reasons to buy
+Two tail lengths+Multi-lens position+Additional features
Reasons to avoid
-Not road race / event standard

A honeycomb front ventilation panel is used on this time trial helmet to limit overheating and Lazer’s advanced Turnfit retention system ensures this helmet has a comfy fit that won’t distract you from any efforts.

A spring loaded cover allows you to directly squirt water into the helmet on hot days, while optional ventilation systems allows the rider to choose between optimal ventilation Vs optimal aerodynamics.

This model has a short tail but there are long tail conversion kits available, although it’s not considered road bike event standard.

Best women's road bike helmets

With no destiguishable differences between male and female heads, most helmet manufacturers offer a unisex helmet shapes. Where there is a women’s specific option, this is mostly down to colour ways to match the brand’s kit/ bikes or just offer alternatives, mostly in the form of more elaborate decals.

This is a limited category, with most brands opting for a unsex fit, but as and when we come across brands and models that we would recommend, we'll add them to this best road bike helmet buyers guide.

The Extima is Team Sunweb's helmet of choice as it superbly balances aerodynamics with being lightweight and well ventilated making it one of the best women's road bike helmet for all round racing. An environmentally safe and effective material by X-odour - that neutralises the smell of sweat after a taxing ride - is used in the padding of this helmet.

It is also good to know that the helmet is protected for 12 months under Liv's helmet crash replacement service.

It 's proving tricky to track down in the States at the moment, but as soon as it come's available we'll let you know.

Best commuter helmets

Commuter helmets are all about the practicalities of riding a bike for transport. Coming in a huge range of styles, with a huge range of functions – it’s just a matter of picking one that meets your needs.

Looking cool on your daily commute does not have to be at the sacrifice of safety by not wearing a helmet at all. By all means, if you’re already a rider. just wear you existing lid, but if you’re new and looking for top tips for commuting by bike to work,and on the look out for something specific, we’ve found the best road bike helmets to match with the best commuter bikesthat also combine looks with safety features.

The primary function of a cycling helmet is to protect your head - and all helmets sold by reputable retailers will meet the standards set out by the safety authority in the country of sale.

If you choose to spend more, the helmet won't necessarily be safer but instead may be lighter, and more breathable. The retention system often becomes more comfortable and adjustable on a more expensive helmet.

A safety system called MIPS, Multi-directional Impact Protection System,  will often be referred too when discussing the level of protection. It's considered the industry gold standard of helmet protection and you can read all about it in our guide below.

What are the key features you should look for in the best road bike helmet?

Bike helmet safety

Always check that the helmet you are buying is tested to the standard relevant to where you live: CPSC for the US, EN 1078 sticker for the UK, and Europe. This means that the helmet has passed a number of tests that look at helmet's construction, field of vision, impact absorption, retention system, chin strap and buckle. In order to ride in races, gran fondos and triathlons it is often a requirement to have a helmet that adheres to the relevant local standard.

Road bike helmets and MIPS: what is MIPS and do I need it?

In recent years, we've seen more and more bike helmet brands adopt MIPS. MIPS stands for Multi-directional Impact Protection System; MIPS is actually a brand in itself, and helmet providers using it build the layer into their own helmets. Some brands like Bontrager have their own similar systems.

The MIPS liner is designed to reduce rotational forces on the brain that can occur in the event of a crash, creates a slip plane to mimic the brain's own protection system to minimize force transmission to the brain.

Helmets with MIPS layers often cost a little more - but there is some evidence to suggest the layer is effective in reducing injury in certain types of crashes.

Road bike helmet fit

If a helmet doesn't fit properly then it will not do the job it is designed for. Helmets are often available in different sizes relating to the circumference of your head, and while you could measure your head with a tape measure and buy online, we strongly advise going to a bike shop and trying a helmet on before you buy it.

You are going to be wearing the helmet a lot, potentially for over five hours at a time, so it's imperative that it is comfortable. It is also advisable to try on a variety of makes and models to see which is most comfortable and the best road bike helmet for you, as they are often different shapes internally.

Some helmets are women's specific and even feature a special gap to allow for a ponytail, such as Specialized's Hair Port system. However, most helmets are unisex and will fit both men and women.

Bike helmet adjustment/retentionsystem

The retention system is used to adjust the fit of the helmet to your specific head size. These are commonly adjusted by a dial or some kind of ratchet system. The best road bike helmets can be operated with a single hand, which is useful for making slight adjustments on the move.

It should be possible to loosen the retention system on a helmet to allow for a thermal skull cap or cycling cap to be worn underneath. This is done for added warmth, and the bill of a cycling cap can be useful for deflecting rain from the eyes. Because of this, caps are a common sight in the spring classics, such as Paris-Roubaix. If when you try on a helmet the retention system is on its limit, it is probably the wrong sizefor you.

Bike helmet comfort and padding

Padding makes a helmet more comfortable but also helps to wick sweat away from your head. An ideal road bike helmet design will feature padding that can be removed for washing and replacement.

Bike helmet venting

These are holes in the shell of the helmet. They have two functions – to reduce the weight of the helmet, and also to add ventilation. Helmets with fewer or no vents are usually considerably warmer, though the latest crop of aero lids has shown the value of well designed internal channelling. This might not be obvious when you try one on in a shop, but once you start working up a sweat climbing a big hill when hot weather cycling ,it becomes invaluable.

Bike helmet weight

As is common with cycling kit, as weight decreases price tends to increase. The best road bike helmets will be lightest in their given category, making them the most comfortable option because they don't place less strain on your neck. If you're a competing cyclist the other advantage of a lighter helmet is increasing your power to weight ratio, 50g might not make much difference to most of us mortals, but to a top professional looking for any marginal gain, it becomes significant.

Different types of road bike bike helmet

Leisure/commuting bike helmets

These kinds of helmets typically range from $50 / £40 to $100/ £80 and are ideal for those getting into cycling, or those who aren't troubled by and extra 50-100g of weight. They tend to be just as comfortable in terms of padding as more expensive helmets, but with a slightly heavier weight.

A good example is the Smith Optics Signal ($75/£65 ), pictured above. The Specialized Echelon II ($90/ £50 is another great road bike helmet option, although there are many more.

Performance road bike helmets

These are the best road bike helmets for all round performance and are among the lightest and most breathable options available, used by professionals during races. As an aside, helmet vents can be useful for stowing glasses, when not being worn and offer plenty of angles to get at an itch on your head.

Time Trial bike helmets

Time trial (TT) helmets are designed to be worn during time trials and are not permitted in standard UCI road races, but are permitted in UCI TT's if they carry the necessary safety credentials . They are also a popular option for triathletes and track riders as they are the best road bike helmet for minimising drag. These helmets often feature elongated or teardrop shapes to maximize aerodynamics, but venting is minimal, as vents create drag and visors are common. Do not show up to a sportive or Sunday ride in a time trial helmet, unless you enjoy being ridiculed.

Aero road bike helmets

A helmet type that has become increasingly popular in the last few years, an aero road helmet is a cross between a traditional road helmet and a TT helmet. They are designed to be more aerodynamic than a standard helmet, but this means they sometimes try to reduce drag by featuring less venting, generally making them slightly heavier and warmer, although in the best aero road bike helmets it will negligible. This breathability / weight trade-off is worth it for breakaway riders and sprinters. The Specialized Evadeand Smith Ignite are good examples.

Road bike helmet top tips

Some best road bike helmet manufacturers offer a crash replacement scheme, where you can buy a cost price replacement if your helmet is damaged within the first couple of years of the original purchase.

Most helmets are made from expanded polystyrene, with an outer polymer shell, covering this. During a big impact, the polystyrene is designed to absorb energy and compress. After a crash, the outer casing can hide the compromised polystyrene underneath, and look undamaged. Always replace your helmet after a crash or impact, and check it regularly for wear and tear.
