If you stumbled on this blog, you are probably trying to better understand your bicycle neck brace, or the process of buying a neck brace and how to fit it properly.
Leatt DBX neck braces have a ton of adjustability. The need to fit the rider well in order to deliver on their promise to cut down on the chance of severe neck and spine injury. It has been discussed at length on our site, as we examine Leatt products, how these neck braces function and how they deliver on their promises and price point. The central principle behind Leatt bicycle neck braces is Alternative Load Path Technology (ALTP).
Alternative Load Path Technology transfers the force of a crash or impact from your head and neck to other muscle groups including your chest, shoulders, and back. When fully outfitted in a full face helmet and Leatt MTB/BMX neck brace, you are more likely to walk away from a major incident without lasting or impactful neck injuries.
One thing we noticed, however, when examining Leatt neck braces, is how fit can impact or even mitigate the effects of Alternative Load Path Technology (Check our guide on how to fit a Leatt Bicycle Neck Brace). If you don’t adequately measure and size your neck brace when you buy it, you already do a disservice to the product and how it works.
One of the most important facts in Leatt bicycle neck brace fit is deck height. Many might not understand what deck height means, or how to size appropriately for it.
Deck height refers to where the striking platform of the brace sits in comparison to your shoulders. The striking platform is the padded area that goes around the brace, or in other words, anywhere the full face helmet might strike during impact.
Why deck height is important is this, if the DH isn’t correct, the head will have too much room to aggressively move during impact, thus mitigating the level of protection provided by alternative load path technology as well as the brace. Deck height MATTERS.
We noticed in our time examining Leatt’s bicycle neck brace models that not all models have the same deck height. In fact, the change in DH from the Leatt DBX 4.5 to the 5.5/6.5 is quite significant.
The 4.5 brace sits about an inch and a half higher than the 5.5 and 6.5 braces. It also offers fewer adjustability options, so deck height isn’t able to be changed like with the 5.5.
The Leatt DBX 5.5 features removable adjustable height pads which can increase and decrease the deck height to better fit to the rider. This can add some wiggle room for riders willing to spend for a higher model brace.
When purchasing a Leatt bicycle neck brace, you should take and measure what is an appropriate deck height for your body composition.
A word of advice, if you are a taller, slenderer rider with a longer neck. The brace for you is most likely the Leatt DBX 4.5. If you are of average height or build, the 4.5 will not suit your body type, and a 5.5 or 6.5 neck brace is going to be in your sweet spot.
