Double D or Micrometric closure: Which one do you choose?

Every helmet, of course, has a chinstrap closure. It is even mandatory to ride with a closed chinstrap. This is mainly for your own safety so that the helmet cannot fall off during the ride or a fall. There are different types of helmet closures that can vary from helmet to helmet. For example, these fasteners all have a different mode of operation that makes them unique.

The Double D closure

The Double D closure is the most reliable way to close a helmet. This way has been used for years in helmets. The closure is attached with two buckles and a strap. Then the strap should go through the two buckles and return through a buckle. In this way, a block is caused, so the buckle cannot easily open while riding a motorcycle. This is because it has a simple design that can only get tighter under pressure. This clasp will not, like other types of clasps, break on the clasp. A disadvantage is that it is more difficult to close this closure, especially with gloves on!

The Double D closure is mandatory when riding in competition. This is because this closure is the safest when falling and at high speeds. Moreover, this is also the oldest way in history to close a helmet.

The Micrometric closure

The micrometric closure is widely used in helmets. It is especially an easy and user-friendly way to fasten and unfasten the helmet quickly. This fastener is attached by teeth that go over a ribbed metal plate and click into it so that the fastener does not loosen quickly. You can think of a tie-wrap, this has almost the same effect as this helmet closure.

The micrometric closure is a common closure because it is easy to use. There are several different types of micrometric helmet closures. For example, there is a metal version and a plastic version. Despite the metal version being the least common, it is the stronger of the two. This is because it is less likely to break than the plastic micrometric closure. This type of closure is also called a quick release closure.

For example, Nolan has another variation of the micrometric closure. This closure has two closures in one. On the chinstrap, there is a plastic and metal closure. This makes the helmet less likely to open and a lot safer. This closure is patented and can therefore be seen on a few Nolan helmets, for example, the N100-5.

The Fidlock closure

The Fidlock closure is not very common on helmets. This closure works by means of a magnet. This makes it very easy to use and makes it the ''easiest'' fastener on the market. In our assortment, we have the Klim Krios pro as the only helmet with a Fidlock closure.

The Quick release closure

The Quick release fastener is the least common on helmets. This is because it is the least secure of all the helmet closures, and the Micrometric Closure is often used in its place. The Micrometric buckle is the first to break when testing all four different buckles. There are therefore few, if any, helmets with this closure in the ChromeBurner assortment.

All in all, there are different types of helmet closures with different functions. All closures have been tested and are therefore safe to use. There is a difference in the degree to which they are safe. The Double D helmet closure is the safest, followed by the micrometric closure. This can also be seen from the numbers in our range. There are relatively few Fidlock and Quick Release helmet closures. Furthermore, almost all closures are easy to use and therefore suitable for everyone.

The Double D buckle is the oldest and safest way to fasten a helmet. It can be used for all riding styles, unlike the Micrometric chinstrap. The Micrometric chinstrap is not allowed in competition due to its high speed and the risk of falling. The Micrometric chinstrap is easier to use, especially with gloves, than the Double D buckle. So it really differs what kind of rider you are.
