6D ATR-2 Off-Road Helmet

Cycle News Staff | February 26, 2018

The ATR-2 off-road helmet from 6D Helmets uses Advanced ODS technology | The ATR-2 has an evolved version of the company’s signature Omni-Directional Suspension system (ODS). The updates were heavily influenced by the work 6D completed inside the NFL’s Head Health Challenge III Contest, in which 6D and testing partner Dynamic Research, Inc. were selected as the Grand Prize Winner.

The ATR-2’s Advanced ODS is highlighted by a new Expanded Polypropylene (EPP) multi-impact outer liner and a new Expanded Polystyrene (EPS) replaceable inner liner. As before, the two liners are connected via a series of elastomeric isolation dampers, assisting in progressive loading of the ODS system during impacts. Now, however, many of those dampers have been replaced by damping towers that are incorporated into only the outer liner; these towers are capped by new, low-friction disks that slide freely against the inner liner, thereby reducing friction under loading and increasing the displacement travel between the two liners.

“Through material testing and analysis made possible by the NFL Head Health Challenge III Contest, we were able to unlock additional potential from our ODS system, and we’re proud to have incorporated these improvements into the new ATR-2,” said Robert Reisinger, 6D’s Director of Engineering and cofounder. “With this new Advanced ODS system in place, the ATR-2 offers improved performance in both linear and angular acceleration mitigation, and at the same time can be made easily rebuildable for a longer service life. This improves rider safety and saves the consumer money.”

In addition to Advanced ODS, the ATR-2 features a number of other updates aimed at improving safety: A structural Brow Rib strengthens the upper eyeport area, while a strategically designed Cervical Protection Zone works to protect the rider in the event that the helmet is pushed down and back into the neck and spine during an accident. The ATR-2’s shell has also been optimized to perform in concert with the Advanced ODS.

In addition to its improved low-, mid-, and high-velocity impact mitigation, the ATR-2 has an overall weight reduction of about 100 grams. The helmet also features a removable, washable comfort liner with a genuine Dri-Lex antibacterial fabric, as well as 17 transfer ports that work in unison with the Air Gap Ventilation System to keep the rider cool. The new EPP chinbar is over-molded with polyurethane at the sternum pad location and is more energy-absorbing for side impacts to the jaw area.

Safety features carried over from the revolutionary ATR-1 include a clavicle cutaway, sternum pad, shear-away visor screws, and emergency removable cheekpads. The ATR-2 is available in three shell sizes covering a size range from XS to XXL and comes with a three-year limited warranty. MSRP starts at $695.
