9 Best Convertible MTB Helmet For Enduro And Trail Riding Reviews 2021

best convertible mtb helmet-enduro mountain bike helmetTo find the most updated and best convertible MTB helmets we did research over several models in the market. We observed that new coming MTB helmets with removable chin bar are more upgraded than the earlier editions. Latest helmets are making use of quality material with improved construction techniques. We assessed these convertible helmets after considering their weight, comfort, ventilation, protection, and convertibility.

Convertible helmets are becoming popular among riders because of their versatility on the trail. In simple words, you get two great helmets for the price of one. These convertible helmets are also perfectly suitable for enduro racing and trail riding. A rider needs full-face protection for enduro racing and improved ventilation while climbing uphill. Not all convertible helmets are certified for downhill riding. So, read specifications carefully before purchasing any helmet.

Two things in one design need some compromises!

Extra structural elements to remove and reinstall the chin bar make these helmets a little heavier than the full-face helmet. Moreover, after removing you have to carry chin bar somehow.


Before purchasing any helmet you need to confirm your head circumference. Most common helmet sizes available in the market are:

  •      Large:23.25″–24.75″
  •      Medium:21.75″–23.25″
  •      Small:20″–21.75″

Overview Of Main Features

Our team recommended this best convertible mountain bike helmet for riders who want a lot of ventilation in both open face and full face modes. During the trial, I found the removal of the chin bar through 3 visible clamps is relatively easy. But there is a need to take off this helmet to reinstall its chin bar. There are two clamps on each side near the ears and one on the rear side of the helmet.

In open face mode, this helmet is very lightweight (0.99 lb) and comfortable. After detaching the chin-bar, the non-twist-able chin strap is still part of the helmet. Moreover, I did not feel any listening problem with this helmet on my head. In open face mode, this helmet is the best for trail riding. But there is a need for a backpack to carry the chin bar after detaching.

Its chin bar with cheek pads not only offers a snug fit but also makes this helmet less bulky on a rough trail. Its inner pads are easy to remove for washing purposes. Moreover, its XT2 padding has woven in silver fiber which has anti-microbial properties to keep this helmet free from sweat smell. After evaluation, our safety experts also approved it as the best enduro MTB helmet in full-face mode.

Its Float fit retention system helps me to do the fitting adjustment with micrometer sensitivity. For my intermediate oval shape head, this helmet sits perfectly and there is no pressure point and undue movement.

During testing, I moved its sun visor up and down with one hand. This easily adjustable visor helped me to keep sunlight out of my eyes. Moreover, there is enough space to park the goggles underneath the visor after moving it to a high position. This adjustable visor is also removable by using a screwdriver. Furthermore, this helmet comes with a “breakaway camera mount.

Its EPS inner core is covered by a hard polycarbonate shell to create a sturdier helmet. This helmet gives excellent coverage to the rear side of my head. Moreover, Its slip-plane MIPS technology adds more protection against the impact of rotational forces. Our head of testing team ensured that this helmet can save the rider’s head in case of an accident.

Overview Of Main Features

In simple words, Bell super air R is the updated version of bell super 3R. This latest model resolves all the issues of Bell super 3R but its high-end features cost some additional price. During the examination, I found its chin bar removal or re-installation mechanism is more convenient than super 3R. In this latest model, the chin-bar back buckle is eliminated. So, everyone can remove or reinstall its chin bar without taking off this helmet.

Moreover, this helmet weight is 144 grams less than bell 3R. Bell Super Air R has a lot of vent openings. There are 18 vent openings integrated with 5 full-length front-to-back channels on the top of the head. I found this helmet ventilation system very effective. Its 4 over-brow vents are also integrated with air-channel matrix in EPS foam to maximize cool air circulation over rider head.

One of the most notable improvements that Bell made in this model is spherical MIPS technology. In spherical MIPS technology, there is an inner EPS core that sits firmly against your head and the sliding plane is now hidden between EPS core and outer shells. All these results in enhanced protection & comfort level of this helmet.

There are 3 soft detentes as you raise or lower the sun visor. During the trial, I face no problem in goggles storing underneath the visor after moving it to a high position. As compare to 3R, its X-static inner pads also have sweat guide channels to drip sweat away from your brow. This feature is very helpful to keep your eyes sweat-free in a hot humid environment.

The protection level of this best mountain bike helmet is enhanced by adding dual-density EPS foam. Dual-density core gives excellent protection for high and low-speed impact. Our testing and safety experts recommended it as best enduro mountain bike helmet.

Last but not least, there are two replacement cheeks pads and a removable Go-Pro mount in accessories.

Overview Of Main Features

This is the only BELL convertible helmet that is certified for downhill riding or BMX racing. BELL super Air R and 3R are the best trail MTB helmets but not certified for downhill cycling. However, high-end protective features make this helmet expensive and heavier than other BELL convertible helmets. Our experts recommended it as the safest convertible helmet for downhill riding.

Moreover, its chin straps are easy to buckle with magnetic FIDLOCK. This magnetic buckle is easy to manipulate with one hand. Its mechanical engagement keeps it securely locked.

During the evaluation, I removed its chin bar through 3 visible clamps without much effort. But I have to take off this helmet to reinstall the chin bar. There are two clamps on each side near the ears and one in the backside of the helmet. 

It’s variable density EPS foam can better manage energy transfer to rider brain from different speed impacts. Moreover, its flex-spherical MIPS technology can properly address rotational impact. This helmet has won rider confidence by saving many people lives who met some serious accidents.

Its X-static pads are designed in such a way that they can channel the absorbed sweat to drips away from your brow. These X-static pads are also washable. The pads are attached to the helmet interior with double side tape. I feel this helmet a little bit tight against my face but it’s not up to an uncomfortable level.

Its float-fit race system is featured with a rubber over-molded dial that is suspended off the back of rider head. This dial allows me to do the fitting adjustment with micrometer sensitivity. My head shape is intermediate oval and has a circumference of 23″. So, I try large size that sits on my head comfortably and there is no pressure point.

Its ventilation system has 2 brow ports and 19 helmet vents that allow cool air to intake and push hot air out. But I did not find its ventilation as effective as Bell super Air R. Overall it is the best helmet for enduro and trail riding.

Moreover, its adjustable visor can accommodates both goggles and glasses. You can also remove visor from the helmet when you want. Its Seamless camera mounts require no zip ties or tape.

Overview Of Main Features

Giro switchblade offers the best coverage to my face and head like a full-face helmet. After detaching the chin bar, there is still excellent rear head and ears coverage. Moreover, the Giro switchblade is the most easily convertible helmet in the entire list of our recommendations. But I felt Giro switchblade hotter and heavier than Bell super 3R which is almost the same in price.

To detach the chin bar there are buttons on the left and right side of the chin bar. Attaching and detaching of chin bar becomes simple for me after some practice. I did not feel any need to take off this helmet to reinstall the chin bar. Everyone can do it by just aligning metal lugs and click them in place.

The washable inner pad lining of this helmet is hydrophilic and antimicrobial. These pads can absorb sweat up to 10 times more than its weight without giving any sweat smell. Its Roc Loc adjustment system includes a back knob that help to make a quick adjustment with one hand. Moreover, its MIPS technology lets the helmet slide relative to the skull and adds more protection against the rotational force transfer to the brain.

For my intermediate oval head, I did not experience any pressure point or undue movement due to its rubber-padded cradle. During testing, I moved the visor up and down in 4 steps with one hand. It helped me to keep sunlight out of my eyes in every situation. These 4 steps include three riding positions and a high position to store the goggles above your brow.

It’s Roc Loc Air DH fit system helps in balancing this helmet slightly off the top of the head which allows more air to pass over the head. Moreover, there are 20 vent openings to allow cool air circulation but I found this helmet relatively hotter. However, this helmet does not limit your hearing ability because there are two large vent holes perfectly above your ear. Overall it is the best convertible MTB helmet that offers good head coverage even in open face mode.

Its chin guard is made of carbon fiber. Moreover, it comes with a standard MIPS system to add more protection against the rotational force transfer to the brain.

Its chin bar connecting mechanism is pretty secure. There are two stainless steel and one carbon fiber tabs on the chin bar which slot into the internal frame of the Zytel helmet. You just need to pull or push a handle lock to remove or reinstall the chin bar. However, I found the chin bar removal mechanism is convenient but reinstalling mechanism is tricky. Moreover, there is a need to take off this helmet before attaching or detaching its chin bar.

Dual flow ventilation through 3 brow ports and 15 helmet vents allows cool air to intake and push hot air out. Moreover, its STACC vent channels intake air through arteries to cool down your head. Its adjustable visor can also park goggles underneath.
