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.

Giro says its Eclipse Spherical Helmet is both the fastest road helmet and the coolest aero road helmet it has ever created. We can't verify the aero claims Giro makes, though it provides data to back it up, but I did find it very effective at cooling, and really comfortable to wear.

Debuted in the World Tour in 2021 and now available to us mere mortals, the helmet's design puts large vents at the front, while the remainder is sculpted to allow the smooth movement of air over the head. It certainly looks more aerodynamic than many of the wide-vented road helmets on the market.

The Spherical Technology powered by Mips is very clear to see: there are two EPS foam layers to the Eclipse, with a Mips liner sandwiched between them, with movement enabled through ball and socket 'elastomeric anchors'.

The theory is that this movement, allowing the top layer to rotate around the lower layer, enables the helmet to absorb as much energy as possible in the event of a crash, reducing the impact on the head.

I was lucky enough to avoid being a crash test dummy, but this is the first helmet I've worn where there is clearly so much movement between the layers.

Some aero helmets can suffer from poorer ventilation than non-aero designs, but the Giro Eclipse performs well on this front. Those large vents at the front, helped by the Roc Loc 5 Air retention system that holds the helmet slightly above the skull, allow lots of air to pass over the head for good cooling.

I even tested the helmet in the middle of the recent UK record-breaking heatwave and was happy with how well it performed.

I also found the Eclipse really comfortable to wear, with plenty of padding and adjustable straps, and a ratchet at the rear to tighten the fit.

The only issue I had was that the helmet sometimes clashed with my sunglasses. I needed to adjust the arms of my Oakley Jawbreakers to their shorter length to avoid any contact, and my Oakley Sutro and Encoders both clashed a little.

Many would agree that the Canyon SRAM racing team has one of the best looking kits in cycling, and this matching helmet follows suit – it's a good looking lid, and the touches of colour are classy. Unfortunately it's not currently an option, so you'll have to settle on one of the five other colours available – white, black, charcoal, blue and black/red.

Value

Top-spec aero helmets with Mips technology don't come cheap, but although the Giro Eclipse is pricey, it's on a par with other brands' top dollar offerings.

Last year, I reviewed Limar's Air Speed helmet (you can read my review here). Limar makes similar claims about its market-leading aero performance, and it'll 'only' set you back £180, but as far as I'm concerned the Giro Eclipse is significantly better performing all round, and much more comfortable. I'd be happy to pay the £60 extra for it.

The S-Works Prevail II Vent helmet, which Liam tested earlier this year, is the same price bar a penny (£240). I have the non-Vent version of this and find it a little more comfortable than the Giro, and I'd say the cooling performance is better, and it was cheaper at £210.

There is a new Prevail 3 coming, but that's £275, as is the new Evade 3, 'the most aero road helmet in the peloton' (Specialized's words, not mine).

Conclusion

Overall, I really enjoyed using the Giro Eclipse. The only issue I found was with my sunglasses clashing, which might not be an issue for you at all. The Mips technology is reassuring, and though the aerodynamic claims are impossible to verify, it passed the toughest of tests on cooling.

Verdict

Impressive all-round performance, a combination of great cooling, good looks and (probably) aero benefits...

Tell us some more about the technical aspects of the product?

Rate the product for quality of construction:
 
10/10

Very high quality construction.

Rate the product for performance:
 
8/10

Comfortable and performs very well at cooling – I can't verify the aerodynamic claims. My only issue with the helmet is that the retention system comes down reasonably low, and I found it clashed with the arms of some glasses.

Rate the product for durability:
 
8/10

Early days, but no issues in the months of testing.

Rate the product for weight (if applicable)
 
7/10

The medium helmet I tested weighed 265g – 5g lighter than Giro claims, and not bad for an aero helmet. At the cost of aero performance, you could find helmets 40g lighter out there but that sort of difference is immaterial in the context of other benefits.

Rate the product for comfort (if applicable)
 
7/10

Comfortable, with good padding.

Rate the product for value:
 
5/10

It's on a par with other top-end aero helmets with MIPS crash protection.

Last year, I reviewed Limar's Air Speed aero helmet, which comes with similar claims on market-leading aero performance, but costs £180. The Giro is a significantly better performing helmet all round, and much more comfortable. I'd be happy to pay the £60 extra.

It's easy to see why this helmet is used by a number of professional cyclists – it's very good, if not quite as good on comfort and cooling as the S-Works Prevail II.

Isn't Giro still owned by Vista Outdoors, the U.S. guns and ammo manufacturer (and NRA funder)?

Well, they sold off the guns (due to widespread retailer boycotts of their other products), still produce and sell the ammo. But in case you thought they'd changed their spots, their CEO Chris Metz can lay your doubts to rest;
"If we’re not the largest industry supporter of the NRA we’re certainly one of the top and that will continue to remain the case. We own more than a dozen leading brands, all dedicated to Second Amendment supporters. It’s the crux of who we are and what we represent. You’ll see that support continue, even more so."

Are you saying it's bad because guns and ammo, or good because it might be bullet proof?

If they have cracked bullet proof bicycle helmets then surely VW/Audi proof models can't be far behind.

I dunno about the US but I understand Australian experience is that helmets may protect your head but that might not solve the problem.

Giro has lost its way. It was the goto helmet in the 1980 and 90. Innovation and on the style front. They are dragging behind. Still producing primary colours which matches no ones kit and their top teer helmets are not inline with the trends of POC and Kask of light and large vents.

New , younger designers required.

I must say my first reaction to that colour scheme was which 1980s video arcade game housing did you pinch it from, and yes, can't see it matching any kit except one specifically designed for it.

I think the article states that the colour shown is not available (it's team kit specific) but there are 5 basic colours on offer.  Given that 2 of the options are white and black, I can't see kit matching for us lot being an issue.

Just to clarify in case it wasn't totally clear - the specific colourway on the helmet reviewed is Canyon/Sram team issue, not available to the public currently as far as I'm aware so it's not really supposed to match anything other than the current Canyon/Sram kit. I'd know because they sent two samples and I managed to 'borrow' the other one, of course it doesn't match any of my kit! Nice lid, although I agree with the comment about having to fiddle with your shades a bit.

Ah mea culpa, missed that sentence. Cheers. Always seems odd to me when teams wear helmets customised to their kit that aren't available to the general public, pro racing is the biggest shop window for high-end helmets, you would've thought the manufacturers would want to show off what we can actually buy, but I suppose they know their business best.

Won't touch anything made by Giro again after their expensive Synthe's retention mechanism made out of the crappiest, flimsiest plastic going unsurprisingly broke after just a couple of weeks of normal use five or six years ago. And Giro's customer service was on a par with that plastic - didn't want to know, didn't give a s**t.

Yes Giro were the helmets to have back in the day but not now. Plenty of choice out there and I'm not paying that much money for a helmet when one 1/3 of the price or even much less than that passes all the same safety tests.
