Review: Met’s new Manta aero helmet adds MIPS and motorsport

First launched in 2015, the Met Manta has been a popular aero road helmet with peculiar scheme cues. Eagle-eyed WorldTour supporters has been possible to discerned a brand-new Manta on the heads of Team UAE riders at both the Belgian’ Opening Weekend ‘ and the UAE Tour. Met has now officially announced an updated Manta, and to say the design is distinctive would be a vast understatement.

Met has retained the recognisable and chiefly closed off frontal area from the previous two iterations of the Manta, with simply slight modifications to the vents. Nonetheless, much like we spotted on a safarus of the Met factory in 2018, all the action is out the back. Met has completely redesigned the rear of the helmet, and it now looks like something straight off a LeMans 24 -hour car’s rear end.

The bike racing and motorsport worlds have a long history of collaborating, despite all that is different between them. Colnago famously worked with Ferrari in starting its first carbon superhighway bikes. Motorsport motorists turn to bikes for fitness, while some cyclists have brought in Moto GP starrings to become involved in condescending. More recently, WorldTour teams and Formula 1 units have shared specifies, patrons, proprietors, and resources.

However, aerodynamics and engineering has now become the major converge parts, with the affects on motif becoming ever more apparent.

Met targeted the rear end of the brand-new Manta to improve ventilation and aerodynamics. The new blueprint pieces air channelling assistants like the “exhaust” and the “rear deflector” that announce more like car divisions than helmet peculiarities. This is not too surprising given Met’s head of design, Filippo Perini, has vast suffer in the automotive world-wide, most notably as onetime Lamborghini chief designer.

The automotive design influences are easy to spot.


Focusing on aerodynamics, Met has created a lower-profile Manta than its precede, which decreases to a tube contour sketch at the rear. With Perrini’s experience, Met first sketched an aerodynamically improved layout before establishing 3D examples, which it authorized utilizing CFD. Finally, the brand-new helmet got the obligatory wind tunnel testing sessions at the Newton Laboratory of Milan.

Met measured the brand-new helmet at 33 km/ h, 50 km/ h, and 88 km/ h in two brain primacies: 77 deg( normal principal arrange) and 65 deg( sprint rank ). The cause of this new design and aero testing is a entail lag reduction of 4 watts in the standard head position and 3 watts in the sprint position.

If these quantities don’t sound big, bear in mind the test compares the new helmet to the previous Manta design, which was already aero. To make this in perspective, Canyon claims the brand-new Aeroad saves 4.4 watts when tested with a equestrian compared to the previous iteration of the Aeroad. While ideally I require the watt savings from both an aero helmet and an aero chassis, the helmet has a much greater watts-saved :p ounds-spent ratio.

Met too claims a same 3-4 W drag reduction compared to an average of four competitor aero helmets but won’t tell us which four competitors.

Unfortunately, with the current weather conditions in Ireland, I couldn’t properly test the helmet’s ventilation dimensions. As an aero helmet with a closed face, it consequently endangers breathing in some manner. Met does say the helmet has 15 vent-holes, but this does include the rearward-facing deflector complex, which alone peculiarity a total of eight vents.

Met claims the combined effects of the brand-new internal appearance, the NACA vent retained from the previous pattern, and the brand-new back weary generates a low-drag, high-airflow channel, which improves ventilation.

Vents and breeze canals are said to combine to improve ventilation by effectively driving a constant breath flood through the inside of the helmet.

Claims of aerodynamic improvements are to be expected with an aero helmet but can be difficult for an end-user to support or even feel. Thankfully aerodynamics was not the only neighbourhood Met searched to improve with the new helmet blueprint. Met says safe, fit, and wording are also among key thoughts, with security being the number-one consideration, even ahead of aero.


The brand-new Manta features MIPS C2 Essential brain-protection system from MIPS’ recently categorized reach. This is the first time Met has included the MIPS rotational vigour protection engineering on the Manta. Given that neither the previous Manta nor the Trenta 3K peculiarity the psyche safety engineering, it is good to see that it’s included on the newer models.

Fit and comfort

Fit and consolation are inextricably linked but too highly personal. The brand-new Manta is well equipped to suit numerous leaders, borrowing the Safe-T orbital retention system found on the Trenta 3K. The system offers the horizontal and circumference revision am looking forward to a fee helmet plus diameter change for the occipital pads. Despite offering extra personalisation to the helmet’s fit, occipital pad readjustment is included in relatively few helmets.

The Safe-T Orbital Fit System has a rotating tensioner with vertical change as is common on modern helmets. But Met has also computed occipital pad width change for a more personalised fit.

A retention system’s impact on the straps is an often forgot phase of helmet fit. Out-of-position fastens is likely to be awkward or pull on certain areas, such as under the chin. This is particularly important on an aero helmet, where loose-fitting straps can refute aero gains.

Met has exploited a low-profile strap divider on the brand-new Manta which, with merely a few minutes of change on first utilization, I was able to set to achieve that perfectly snug and aero leash antagonism. The belts are lightweight, and the thin divider conveys the whole system is barely noticeable when riding.

Met has added a magnetic buckle from Fidlock. While this is a neat feature, it solves a problem I don’t believe existed. Call me old-fashioned, but I elevate the purity of a traditional excerpt. The magnetized buckle here is a little bulkier, and although it can be fastened one-handed, it is still easier and quicker to use both mitts.

Magnetic fastens equip a neat piece but offering little or no functional welfares.

The test model size medium Manta weighs in at 247 g( CE version ). This is by no means a super-light helmet and is 47 g heavier than the previous Manta’s claimed heavines, but it is respectable for an aero helmet sport MIPS protection.


Beauty is, of course, in the eye of the bystander, so I won’t attempt to review the new Manta’s wording, especially given the inclusion of that rear deflector which will no doubt prove fateful. In saying that, I do like the helmet and especially the colour straddle Met has offered. While not a enormous array of emblazons, the six options provide a mix of rich glossy emblazons and stealth matte finishes.

The helmet appeared to be a solid flat blacknes with no detail in the pictures Met had afforded prior to the helmet arriving. In reality, it is a mix of glossy and matte finishes with a inkling of titanium fade on the sides, reflective decals, and titanium throughout the rear deflector. It’s a pattern and colour choice which works well together and filches the whole helmet, uttering it a premium look.

The brand-new Manta is quite sleek, with minimal added amount and mode facets I wasn’t expecting.

The helmet is noticeably little bulky than my other helmets. This no doubt helps in terms of aero gains but likewise returns a neater appearance in general. I had noticed this myself, and my bride, who is far less picky about anything cycling, noted the same … so it must be true.

Met likewise claims the helmet is” ponytail compatible”, which I have neither participated advertised before nor been able to test, but I can see how it might work.

Met doubled up the lower line-up vents on the Manta to securely house sunglasses. While I have seen this on other helmets, the Met version is the most secure I have used for sunglasses with standard shaped arms. I regularly use the POC Aim glass, which have wider arms that do not sit just as snugly.

Exploring in style! Selfies are tough but thankfully Dora took over sitting tariffs.

The Manta has been a popular helmet since its inception in 2015. It has also been considered one of the “faster” artery aero helmets. With this update, Met has improved the Manta platform further, improving safety and aero while maintaining its general impression. Ventilation capacity remains unknown, but in every other aspect of an aero helmet, the new Manta smacks the mark.

The new Met Manta MIPS is available now and priced at US $300/ AUS $400/ PS220/ EUR2 50.
