Review: Leatt DBX 5.0 Helmet


In recent years Leatt have successfully established their place in the cycling protection and clothing market and are well known for their high quality products and industry leading levels of protection.  As an added bonus, their designers have been working hard at making their range eye-catching too.

We at Downhill Life are lucky enough to have been testing a number of their products over the past few months and this is the first in a series of product reviews.

Those lines, we love this helmet!

First up is the DH helmet. In 2017 Leatt offered two full-face DH model ranges, the full-carbon DBX 6.0 helmet, and the composite shell DBX 5.0 DH helmet which we have been testing. All of their helmets feature their proprietary ‘360˚ Turbine Technology’, which according to their website reduces up to 30% of head impact at concussion level and reduces up to 40% of rotational acceleration to head and brain, which sounds pretty awesome to us.  Unfortunately we couldn’t find any figures on the effect that ‘MIPS’ helmet technology has as a comparison.

Leatt designs all their products to work with and interface with each other, so this helmet will work perfectly with your Leatt neck-brace. It’ll offer sufficient degrees of movement to prevent restriction out on the trail, yet still ensure your neck is saved in a crash. We’ve experienced problems with other helmet brands knocking the brace when trying to tilt your head further back, as you would do when trying to look further ahead, or riding steep trails.

In terms of sizing and fit, we found that we fitted a one size smaller size than we normally would do, which is likely due to them making use of a smaller outer shell. According to their website “A 10% smaller outer shell, transfers up to 20% less rotational forces to the neck, head and brain”.

“Having used the helmet at the last two EWS races this season, as well as a number of races in South Africa, all of which were in 30deg+ temperatures, I found the ventilation to be surprisingly effective, even at the slower climbing speeds. Understandably most people will be looking at this helmet for DH riding but it is a viable option for enduro riders too, especially if opting to remove the cheek pads on transitions.” – says Martin Zietsman

With regards to the looks of the helmet, this is completely subjective and everyone has their personal preferences. Personally, we love it! The 2018 model is a big improvement on their previous version helmet, which was the butt of many a joke on the MTB forums and out on the trails. A redesigned peak and chin-piece completely changed the look of the helmet for the better.

You can pose like a French model in this helmet.

Securing the helmet is done with ease using theirFidlock’ magnetic closure system, which auto-locks the moment you bring the two parts into contact with each other. Releasing it is just as easy with a simple slide away of the two parts.

Break-away plastic screws hold the adjustable peak in place and Leatt are kind enough to supply a few spare screws with the helmet, just in case.

Finally, for the budding action-sports heroes, Youtube vloggers and anyone else wanting to record their rides, we found it simple to mount a GoPro mount to the underside of the peak or a convenient flat-spot on the top of the helmet.

Science of Thrill!

Some of the specs of the helmet that we’ve extracted from their website:
