The MET Trenta 3K Carbon needs no introduction, the helmet was worn to victory at Le Tour de France, monuments like Liège-Bastogne-Liège and Giro di Lombardia — it’s an all-around performer. The helmet is a frequent choice of UAE Team Emirates due to its incredible adaptability and airflow. It’s versatile, light weight, looks great, and now it’s getting an upgrade.


The new MET Trenta 3K Carbon MIPS is the evolution of the Trenta, taking the same aero shape, keeping the ventilation, and adding a super lightweight MIPS system. MET calls the new Trenta 3K Carbon Mips “the most advanced road cycling helmet we have ever made.”


MET Trenta 3K Carbon Features

The concept behind the Trenta is a fresh feeling helmet for elite cyclists with solid protection. One that could keep the airflow high and the drag low — along with the weight. met-trenta-3k-carbon-mips red

MET was looking to maintain the super lightweight Trenta design and couple it with a MIPS rotation management system. The result is a new 3K carbon fiber shell and the addition of the MIPS AIR for added safety.

MET Trenta and MIPS AIR

The MIPS AIR range is the lightest system offered by MIPS, and unlike the traditional MIPS cages, the MIPS AIR integrates directly into the helmet’s padding. This instigation allows for 10-15mm of relative movement between the energy absorbing layer and the padding.

3K Carbon Technology

MET is thrilled with the carbon technology application in the new Trenta 3K, stating, “the MET Trenta 3K Carbon MIPS performs better than any other helmet on the market.” The confidence comes from the MET R&D team’s ability to employ the carbons elastic modules to reduce the density of the EPS foam by 20% without affecting the helmet’s capacity to absorb energy.

The Venturi effect and NACA vent

What good is an aero helmet in the summer if it’s a sweatbox? MET took some intel developed initially by NACA (a precursor to NASA) and harnessed the “Venturi effect”. The effect in plain terms; the vent pushes out the warm air within the helmet through specially positioned exhausts in the rear, keeping constant airflow without creating drag or catching the wind.

To maximize exhaust, MET constructed two large exhaust ports on the rear of the helmet. The Kamm tail deflector rear inclines at 25°, making it possible for the vents to grow more prominent over the back of the helmet.

The low-profile Kamm tail exhaust of the helmet also has an aerodynamic purpose. It works in synergy with the front vent and the rear deflector to effectively drive airflow and developed through specific wind-tunnel testing in the Newton laboratory of Milan.

MET built the Trenta 3K Carbon Mips so that only 30% of the rider’s head will be in contact with the helmet when wearing it.

This 30% contact allows 70% of airflow space to be optimized while passing through the internal cavity of the helmet, keeping the rider cooler overall.

MET designed the Trenta 3K Carbon Mips with dedicated sunglasses ports and rubberized grips for those who like a place to stash their glasses. Ensuring they will not fall off when you’re checking your computer or hit an unexpected pave sector.

MIPS – can not validate or quantify a single instance of being more protective than any other (current) helmet. They can claim higher weight and cost. I simply do not get it (and more and more have to go out of my way to find non-MIPS helmets for the weight savings). The heavier and more uncomfortable a lid – the less chance someone (novice) will wear one.

Years ago (as in 30) there were some very dangerous helmets (more dangerous than no helmet). The results were quantifiable, MIPS is not. Fear monger marketing….(steps off soap box).

A simple google search for data regarding MIPS helmets provides quite a lot of useful articles about said topic. Perhaps before asserting a claim, one provides proof to said claim? Here are just a few articles and studies regarding MIPS that I have found.


Also, the whole weight argument is absolutely ludicrous. MIPS systems weigh only a handful of grams more than their non-MIPS counterparts, if not the same.

Speaking of fear mongering, methinks you doth protest too much. Perhaps spend less time on the soap box and more time doing adequate research?

There are several MIPS helmets at or under US$50 as well.

Neither price, nor weight are an issue.

Weight is an issue. In my car (at this moment) there are five helmets. The only reason I even wear a MIPS helmet is that I need to have a light on the top of my head (the Specialized one has a flat spot for it).

You can not tell me that in my hand that non-MIPS is not lighter, as it is. You can not tell me that the MIPS is as or more comfortable (as it is not). So, lighter, more comfortable and more airflow – WIN! I don’t need MIPS.

As for your links, none can prove that in any percentage of head impacts that a MIPS helmet provided any more protection than a current non-MIPS hemlet. The comparisons are conjecture and opinion of mostly people who are trying to market MIPS as the next solution to human mortality (with or with our scalp damage).

If you look at reality (I wont waste our time with links)…humans tend to protect our heads. The main goal of a helmet (on a bike) is to deflect and offset a blow to the head (assuming there is no penetrating object). The original 1990’s helmets such as the Specialized Sub6 or Protek Mirage were foam “grippers” that would hit the pavement, grab it and break your neck…and that is when we got the shells on the helmets to slip from the surface of impact in a majority of circumstances. I have seen study after study of a helmet test where a weight is inside the helmet and it is dropped to a sensor below, this is just not reality for most crashes on a bike – in general we are moving forward @ X MPG and going towards the earth in a tangent and at the same time protecting our heads from impact (as it is human nature) and the blow is angular (thus the slip shell). That would be I bet 99.99999% of crashes on a bike.

To the main point, no one can prove a MIPS is more protective in a typical bicycle crash any more than they can prove Boost is better than a bike that is not Boost or Super Boost. Buy what ever helmet you want, buy a suit of armor if you wish – but selling on fear is really a pathetic move for brands to just want to get folks to buy a new lid that is supposedly (but not provably) safer.

MIPS Air is implemented at the pad level with low-friction strips and anchor points for the hook & loop fasteners. The weight difference is virtually non-existent.

I was hit from behind by a car at 50k. My helmet was cracked right through on 2 spots.
The emergency doctor was amazed that I did not have a concussion. He was very interested in my new helmet with MIPS.
When I stopped bouncing on the pavement ,my helmet was sideways on my head and all the inner padding was askew.
I realize this is anecdotal, but I believe the helmet saved me from serious injury, and MIPS was part of the helmet
All my friends thought enough of my experience to update their helmets.
I also updated my ski helmet, and of course I will wear only a helmet with MIPS technology.
