Best Mountain Bike Helmet With Removable Chin Guard of 2020


Mountain biking is the perfect activity for riders who love to blend the fun of biking with adrenaline, as it entails an unpredictable, passionate, and exhilarating experience. I’ve observed that mountain bike helmets with removable chin bars seem to have grown in popularity among newbie or intermediate riders who value the importance of extra protection and versatility.

The latest crop of mountain bike helmets with removable chin bars come more refined than their earlier editions. Although they are suitable for all mountain bike riders, they are especially suitable for racers who may want to alternate their helmet depending on their current race requirements.

Removable Chin Bars

The detachable chin bar is a very handy innovation for any rider who explores variable terrains and conditions.

So, in order not to lumber with a full-face on rides that demand endurance, this type of helmet allows you to remove the chin bar for weight reduction as you climb uphill. Once you’re ready to hit the downhill, you can reattach the chin bar.

Here are 4 of the best mountain bike helmets with removable chin bar on the market today.

Bell Super 3R MIPS Adult MTB Helmet

The Bell Super 3R MIPS Adult MTB Helmet is known for piloting the emergence of the current generation of removable chin bar technology. I actually began my love of detachable chin bar helmets with the Bell 2R way before it got an upgrade in 2017, which focused on improved fit.

Bell Super 3R is a perfect upgrade from Bell 2R. Bell removed and reconfigured certain areas of the interior padding to solve the problem and remade a Super 3R with an added Float Fit retention system. Another important element was the incorporation of the MIPS slip-plane safety technology.

Bell Super 3R MIPS Adult MTB Helmet is available on Amazon.

Why should you choose the Bell Super 3R MIPS MTB helmet?

There are multiple reasons to make the Bell Super 3R your go-to choice, and it’s not just because your protection is number one, even though Bell ensured that this model is MIPS-equipped so that you can benefit from optimal protection.

MIPS is short for Multi-directional Impact Protection System and it describes the cutting-edge slip-plane technology built into the interior of the helmet. Its function is to reduce rotational forces that can come from certain impacts during accidents.

No-Twist Tri-glides: You also get quick-adjustable fasteners that help the straps to stay in position. There are X-static and Xt2 padding that are composed of quick-drying material plus original silver fibers that help inhibit bacterial and fungal growth that can initiate bad odor inside the highly durable and sturdy polycarbonate shell.

Overbrow Ventilation: I’ve always been impressed by the ventilation ports the helmet offers on its brow for cool air intake. They push the air through the air-channel matrix so that riders get full-head ventilation. With 23 vents, 4 brow ports, and 6 chin bar vents, wearing the super 3R keeps you in rare freshness all the time.

With 6 color choices, three sizes, alongside safety certification for standard bicycle use it’s hard to go past this MTB helmet. At a price ranging between USD220 – USD230, I think you’re onto a worthy investment while also having your safety guaranteed.

Pros:

  • Full ventilation
  • Easily removable chin bar
  • MIPS incorporated
  • Breakaway camera mount
  • Smooth integration with goggles
  • Adjustable visor
  • Adequate vision
  • Great variety of color choices

Cons:

  • Not downhill certified
  • Should have a place to carry chin bar when unused

Bell Super DH MIPS MTB Helmet

After upgrading the Bell 2R to the Super 3R in 2017, Bell went further to build the Super DH in 2018. The Super DH is among the comfiest MTB helmets I’ve worn on long-distance rides. It is essentially a beefier version of the Super 3R.

The Super DH is BMX and DH-certified. It seems more comfortable for enduro racers, any uphill and downhill riders or those seeking to make a single helmet trip involving both bike park and singletrack so as to save space in their duffel bag.

Bell Super DH MIPS MTB Helmet is available on Amazon.

Why choose the Bell Super DH MIPS MTB Helmet?

First off, this convertible lid is not only comfy but built solidly with a fusion in-mold polycarbonate shell, plus progressive layering to protect you and have you feel amazing every time.

The Super DH is the first of Bell’s convertible helmets with the ASTM F1952 downhill standard for full-face mode riding. It’s pretty much like the brand’s Full-9 helmet, used widely in the World Cup ranks.

One other unique thing I personally appreciate about this model is that you can remove and fit its chin bar without having to take it off.

Besides that, the lightweight Super DH includes a new in-built MIPS Spherical system that protects your head against any impact resulting from rotational forces upon impact. That’s why its low-density EPP foam is placed in the inner shell inside its main EPS foam shell and then fixed to cover the interior of the helmet’s polycarbonate outer shell.

How good is the ventilation?

Combining the light weight, 19 vents with deep internal channeling, and two brow ports, the Super DH turns quite airy when worn with no chin bar in place.
However, with or without the chin bar on, users of this helmet, experience great airflow. With four mesh-free vents built on the chin bar, breathing remains seamless throughout even on your wildest riding adventures. The helmet goes for between USD300 and USD330 which is pretty good value for its versatility, not to mention that it’s almost as if you’re buying 2 helmets in one.

Pros:

  • Easy to move
  • Wicks sweat well
  • Polycarbonate outer shell
  • Easily removed/re-attached chin bar
  • Awesome ventilation
  • Lightweight
  • ASTM F1952 (DH) & ASTM F2032 (BMX)) certified

Cons:

  • Easily twisted straps

Giro Switchblade MIPS MTB Helmet

The Giro Switchblade MIPS MTB helmet is an ASTM DH-certified helmet with removable chin-bar. From all the tests we ran on the GIRO Switchblade as well as vetting user reviews, there’s no doubt it’s an excellent choice for any rider.

Although I found it felt hotter with the chin bar removed, particularly whilst idle, it was fine when mobile again and not so uncomfortable as to be irritating or annoying. I would certainly be comfortable wearing it for aggressive downhill rides.

Giro Switchblade MIPS MTB Helmet is available on Amazon.

Why should you buy the Giro Switchblade MIPS MTB Helmet?

We always put your protection first and we wasted no time in considering the Switchblade an extremely unique and heavy-duty convertible MTB helmet. It comprises of a MIPS system for smart head protection which means it has you covered when it comes to aggressive and safe riding. No wonder it features pads with layers of material underneath and on top of the helmet’s foam, all designed to move slightly during any angled impact, limiting rotational forces on the brain.

The Giro Switchblade is ASTM DH 1952, EN1708, and CPSC certified and it’s applicable when in full-face or half-shell modes.

With the Switchblade, you can get good ventilation in each setting. But there needs to be improvement when it comes to the airflow you get in the half-shell mode. It allows you to breathe much better than with non-convertible helmets with over-the-ear extensions and high-cheek zone that reduces airflow. When set at full-face setting, speeding down the trail comes with impressive airflow and that’s important.

The visor of the Switchblade is pretty solid and works excellently in full-face mode though it always looks a little weird when pointed towards the sky. The box includes a spare visor that features a camera mount. In terms of pricing, it sells from between USD250 and USD270 which is more than reasonable.

Pros:

  • Great fit system
  • Easily switchable between full and half-shell configurations
  • Awesome ventilation for the category
  • Additional coverage in half-shell mode
  • Fully downhill certified

Cons:

  • Thick chin strap which builds up heat
  • Hotter and heavier without the chin bar

Leatt DBX 3.0 Enduro V19.1

As enduro kept rising in its characteristic racing discipline and helmet tech, its status reached a near World Cup-level. This time enduro helmets were offering full-face levels of protection and high breathability. Then in 2016, Leatt joined and launched their DBX 3.0 Enduro removable chin bar. We tested many helmets with chin bars and the DBX 3.0 came out among the best.

Leatt DBX 3.0 Enduro V19.1 MTB Helmet is available on Amazon.

Why choose the Leatt DBX 3.0 Enduro V19.1 MTB Helmet?

First and foremost, the DBX 3.0 is a lightweight convertible helmet that is extremely comfortable. It’s a new model helmet engineered to assist you to change from full-face shred while riding downhill to an open-face design as you traverse to another stage all with the same helmet.

When it comes to your safety, the helmet’s polycarbonate outer shell plus Leatt’s innovative 360 Turbine Technology as well as cushioning material, protect you. Turbines are engineered into the helmet impact foam to stiffen and deform upon impact in order to absorb the vertical and rotational impact forces that could injure you. With the technology, Leatt claims head impact reduces by 30% at concussion level and 40% of rotational acceleration to the head and brain. That’s quite impressive!

Just like me, you too will appreciate the excellent breathable, moisture-wicking, anti-odor washable liner and cheek pads this helmet offers. And who wouldn’t be excited to own a removable chin bar helmet that meets EN1078 and CSPC 1203 certification and comes lightweight at just 760g in full-face configuration?

With 24 vents plus deep interior channeling, the DBX 3.0 is certainly one of the airiest I’ve ever test-ridden. At between USD190 and USD250, this is a helmet that’s definitely worthy of your consideration.

Pros:

  • Reasonably lightweight
  • Pads wick sweat well
  • Breakaway visor
  • Compatible with goggles
  • Reasonable price
  • Good visor adjustment
  • Great magnetic strap and buckle mechanism
  • Comes with extra pad set

Cons:

  • Not downhill certified
  • Very long visor
  • Less airflow than some other helmets in the category
