Amongst these choices, you will discover Trek. The model has been providing distinctive merchandise within the aero helmet house for years and now there’s a new choice. This 12 months the Trek Ballista MIPS got here to market as a alternative for what got here earlier than. It is acquired a radical form and comes with daring claims however what’s it like to really trip with it?
To reply the query, I have been placing it to the take a look at. It is turn into my go-to helmet and it was with me once I headed to California lately. I used to be there to check the FSA Okay-Drive WE 12s groupset with a long-distance trip by the spine of the state however I used to be additionally there to check each facet of the gear I depend upon. Maintain studying to see what works for me, and what does not, with the Trek Ballista MIPS aero helmet.
Design and aesthetics
Earlier than we dive into the main points of the design, it is price speaking concerning the title of the Trek Ballista MIPS. Prior to now, helmets from Trek carried the Bontrager title. It is a legendary title that grew to become synonymous with Trek after a purchase order in 1995. That is when Keith Bontrager offered the enterprise he’d constructed within the hills of California. By that point the Bontrager title had shifted away from affiliation with metal mountain bike frames. As a substitute, it meant high quality elements and since then, that is how Trek used the title.
All issues change although and the historical past that was as soon as latest and necessary is fading. Fewer and fewer folks perceive the historical past of Bontrager. With out that connection to the historical past of mountain biking, trendy customers can solely see Bontrager as a reputation with little that means that Trek makes use of to model componentry. Trek appears to be trying to right that disconnect going ahead and so, increasingly more merchandise bear the Trek model title. The identical persons are designing the helmets as final 12 months, the one distinction is a brand new title on the most recent product.
That mentioned, there’s additionally one other huge pivot implicit within the design of the Trek Ballista MIPS. There was a earlier technology bearing the title Ballista MIPS nevertheless it disappeared when the Bontrager XXX hit the market. The XXX helmet did not use MIPS, it used WaveCel and it got here with a bunch of guarantees concerning the superiority of WaveCel expertise. There was additionally some controversy about these claims however in the end that helmet carried the identical five-star Virginia Tech score that the brand new helmet carries.
On condition that the most recent crop of Trek helmets not makes use of WaveCel, some will learn that as a failure of the expertise. I’d say the true story is that MIPS has continued to advance the expertise that the model has obtainable. Customers discovered first-generation MIPS liners annoying and helmet firms seemed to seek out totally different options. MIPS solved the issue with later generations of the product supplied.
The Trek Ballista MIPS helmet makes use of a brand-new sort of MIPS liner. The purpose of MIPS is to permit the helmet to rotate round your cranium when it is wanted. As a substitute of a cumbersome inside liner, MIPS Air takes the usual helmet padding and coats the again with an ultra-slick layer of vented plastic. Trek then takes that padding and attaches it to the helmet with rubber loops connected to velcro. The unfastened nature of this connection permits the padding to slip towards the helmet and attain the very same factor as the unique MIPS liner however with out the necessity for a liner.

Naming and security apart, what actually makes the Trek Ballista MIPS distinctive is the way it seems. On the entrance of the helmet, you will discover three massive vents. For people who wish to retailer their glasses, the outer two vents add grippy rubber to assist your glasses keep put. As you head again, there’s one other massive air inlet on the prime of the helmet. These 4 vents are the one inlets you’ll be able to see.
In and of itself, only a few huge vents is not all that uncommon for an aero helmet. It is on the again the place issues get a bit more bizarre. The rear of the Ballista MIPS narrows and curves in a method that you simply would possibly acknowledge from the long-tail TT helmets of some years in the past. It is not so long as these helmets however it’s 5-6 cm longer than most traditional street helmets.
What you will discover in that further size is a collection of intricately moulded exhaust vents. In reality, practically the entire rear of the helmet is a single exhaust vent. The house breaks up into 5 totally different, downward dealing with, channels however the dividers are a number of the narrowest items of froth I’ve ever seen on a motorcycle helmet. The periphery comes down behind the ears to type the skin channel but in addition to type a skeleton assist system. It will definitely makes its method to the again fringe of the helmet with a collection of stylish curves that look formed by the wind tunnel. The channel dividers seem like extra targeted on supporting the first construction than creating particular air channels.
Coating the outrageous, fashioned in CFD (Computational Fluid Dynamics) and the wind tunnel silhouette is a selection of 4 colors. The wildest of these could be the colour-shifting matte purple flip that is a bit oil-slick and a bit chameleon. Otherwise you would possibly contemplate the white/nautical navy group color choice extra audacious regardless of an objectively much less eye-catching color combo. For those who actually wish to fly beneath the radar, as a lot as doable with this helmet, then you may also select both matte black or gloss white.

Efficiency
As quickly as I took the Trek Ballista MIPS helmet out of the packaging, I used to be in love. Straight away you could possibly inform it was exceptionally gentle. Trek claims the helmet weighs 275 grams which places it as a couple of grams heavier than the Velocis MIPS helmet launched on the similar time. As a substitute, I weighed my pattern at 260 grams which matches the quoted weight of the “lighter” helmet.
Though I verified the quantity a couple of instances on totally different scales, there’s truly extra to it than the quantity on the dimensions. There is a feeling of lightness that the Ballista MIPS has that’s extra about the way in which it is formed. For those who’ve ever held a bit of carbon fibre that appears impossibly skinny and lightweight however is concurrently stronger than metal, that is the sensation. The rear of the Ballista makes use of a collection of skinny and slim helps across the exhaust ports which might be uncommon and interesting for a helmet. In fact, none of that’s the precise expertise of carrying the helmet.
Relating to carrying the helmet, the very first thing you discover is the strap system. Begin on the left aspect and the “Y” connection is an easy buckle that opens and closes. Modify the principle buckle as far ahead as you need then any further materials will feed again into the remainder of the system.
The rear cradle makes use of a plastic assist that stands out from the centre of the again venting. On the prime is a information for the strap. Get the strap the place you’d prefer it and maintain chasing the surplus to the opposite aspect. There’s one other easy buckle on the Y junction and you may feed any extra to the top of the system the place it is price reducing it off. There is a rubber wrap to assist maintain extra from flapping however, a minimum of for me, there’s plenty of extra.
What’s nice about the way in which the entire system works is not only that it is simple to regulate the place the strap sits. The rear cradle attaches to the perimeters with a really skinny string that winds right into a rear BOA dial. It is exact to regulate in addition to permitting it to fold for storage and journey. To regulate the vertical top of the rear cradle pull it freed from the rear assist then fold it in and push it into a distinct spot within the assist.
Though it may be annoying to have the rear cradle come free when taking off the helmet, the system may be very snug to put on. There’s an enormous house for hair and air is ready to come straight by the inlets within the entrance and out the exhaust with nothing in the way in which of airflow. It is also helpful if you must journey as a result of you’ll be able to unhook the rear and get it out of the way in which of any potential harm.

As I already mentioned, airflow is superb from entrance to again however that does depend upon motion. The anticipated behaviour for all aero helmets is that it’s essential to be shifting to remain cool. I am unsure I truly agree with that. When it is sizzling and you’re climbing, it is sizzling no matter open vents or not. Nonetheless, the design of the entrance helps this explicit helmet.
On the entrance of Ballista MIPS there are three massive channels on the within. These channels assist dry the padding on the forehead the place sweat collects most. I’ve additionally discovered that when sweat does begin dripping, one thing concerning the design retains it connected to your face. As a substitute of getting it drip on my glasses, I discover it runs behind the lenses and the padding is fast to dry throughout a descent. Personally, I discover this behaviour preferable as I by no means stash my glasses.
In some methods although, all of this dialogue to this point misses the purpose. That is an aero helmet, you wish to know if it is quick. Sadly, I can not straight reply that. The knowledge from Trek is that the model performed repeated rounds of CFD modelling in addition to 5 rounds of wind tunnel testing. The testing lined 3 totally different speeds and two totally different positions with a motorcycle, model, and helmet. The outcomes of that testing was that the Ballista outperformed all earlier Trek/Bontrager helmets in addition to the unnamed, peer helmets the model examined. The Ballista saves 10.1 watts versus the brand new Velocis or 5.6 watts versus the prior technology Ballista and although Trek was not particularly testing towards TT helmets, the outcomes indicated “very aggressive efficiency.”
What I can inform you from my very own expertise is that you could generally really feel the lengthy tail within the wind. For those who flip your head a bit, you will hear a particular change in pitch. In sure conditions, you may also really feel the push of the wind. If I maintain my head centred, it does not appear to matter if I am holding place or permitting myself to look down.

Verdict
I want I may discover some method to convert all of the totally different numbers and charts to inform you if that is the quickest aero helmet available on the market proper now. I misplaced hours attempting to do this however in the long run, I simply haven’t got sufficient data. It is as quick as some TT helmets so I might say that is a sign there is a stable variety of watts doable. That is not a comparability to different aero helmets although. Lots of in the present day’s greatest aero street helmets may seemingly declare the identical efficiency as TT helmets from only some years in the past. Which means, as with all aero helmets you have to to resolve if that is the correct helmet for you primarily based on different particulars.
The Trek Ballista MIPS is my present favorite helmet as a result of I discover it snug, gentle, and classy. Type issues and whereas I can not show it is quick, it actually seems quick and I like that. Past that, I really like how gentle the helmet is and I really like that you could fold the rear cradle into the helmet. That element is nice not just for storage on a shelf but in addition when travelling. If that rear cradle stayed put a bit higher, I’d name this the proper helmet.
