The majority of cycling helmets are made using an EPS foam liner. This material is effective at defusing impacts above a certain speed, but does not crush early enough to address sub-concussive impacts. That’s why several brands have begun experimenting with non-foam liners, which can be tuned for lower speed impacts, yet still offer protection against larger hits.
One such brand is Smith, whose helmets are built using a combination of traditional and nontraditional materials. The main protective structure is made from Koroyd, which consists of thermally welded plastic tubes whose thickness can be adjusted precisely for specific impact zones.
This blend of technology is exciting from a safety perspective, but with a retail price of over $200, the helmets were on the expensive side. That’s changed with the new Rover and Route.
Both of these helmets are built using a combination of Koroyd and EPS, and have a base price of $150, wile a MIPS version is available for $30 more.
