Every year there is one product that jumps out of the
crowd. This year it was 6D Helmets’ ATB-1 Carbon full-face mountain bike helmet. The company uses a new
technology called Omni-Directional Suspension (ODS)
that is a fully active, in-helmet suspension and kinetic
energy management system. The mechanics, engineering,
materials and manufacturing are very complicated, but
actually, the concept is quite simple.
To manage kinetic energy (including linear, angular
and lower-threshold acceleration energy), the ODS
system starts with an internal EPS liner not unlike
traditional helmets. With the ODS system, the EPS
liner is divided, creating a compound-liner assembly.
These two liners are separated by a specifically
programmed array of elastomeric isolation dampers, creating an air gap. It is this array of isolation
dampers surrounding the entire liner, combined with
the air gap, that affords the free-motion suspension
capability of ODS.
The company feels their ODS system protects
the rider’s head over a broader range of energy
transfer, especially angular acceleration in low-and

Linked in the middle: The all-new Breezer MLink places its pivot in the
middle of the chainstay, balancing out opposing forces that they claim a
traditional rear suspension introduces. MLink’s claimed anti-squat and
anti-rise design creates an efficient platform that balances out opposing
pedaling and braking forces.
