Endura MT500 helmet

The Endura MT500 helmet has been with us for a few months now and is performing as beautifully as we’d expect from anything bearing the MT500 name. After all, the MT500 jacket was one of our favourite products of last year.

Whilst I’ve yet to bury my head into the floor in Endura’s new helmet the fit, comfort, features and (albeit on paper) protection has been excellent. Of all the helmets we’re reviewing at the moment it’s the one that I keep reaching for above all others.

Koroyd technology

See all those little drinking straws inside the helmet? That’s from a company called Koroyd and is what makes the Endura so special. It’s one of only two mountain bike helmets that uses the technology right now.

There’s a lot of pretty complicated stuff behind Koroyd, but essentially the helmet is lined with hundreds of little plastic tubes which work together to act as a protective, breathable layer.

Koroyd say that up to now helmets have taken materials from the packaging industry to protect our heads. Their technology is the first, we’re told, that is designed specifically to improve energy absorption and safety for riders.

They claim that the helmet standards we use today are 20 years out of date. Those standards allow helmets to be certified as ‘safe’ whilst presenting anything up to a 77% chance of fatal injury when being bashed within what the tests say are acceptable. Koroyd claim that their technology brings that risk right down from 77% to less than 5%.

I don’t have a lab to test the claims and I’m no scientist, but the evidence on their website is detailed, well layed out and convincing. There’s few helmets that give you that level of detail into the protection you’re choosing to trust your brain with.

The evidence – on paper at least – suggests a helmet that is going to do a great job when you inevitably dive head first into the trail.

Koroyd’s push is to encourage helmet manufacturers to go above and beyond the current helmet standards. The goal of the Koroyd initiative is “to reduce the correlated risk of suffering a skull fracture or a fatal traumatic brain injury to less than 5%, according to the Prasad/Mertz risk curves.”
