No anthropomorphic test device (ATD) neck or effective torso mass was used, similar to a number of previous cyclist oblique head impact studies.2,26,27,40 Although some studies have used a Hybrid III (HIII) neck for this type of testing,1,22 oblique impacts may subject the neck to considerable axial compression for certain impact locations, a scenario in which the HIII neck is known to be overly stiff.2,28,38 It has been further suggested that human necks have minimal effect on initial head impact response during head-first impacts due to the high loads and short durations involved.12,28,38 Impact conditions were selected to reflect those common in cyclist crashes as determined by helmet damage replication studies and computational simulation studies.5,31,39,41,42 Six locations dispersed around the helmet were selected to assess helmet performance over a range of impact scenarios (Fig
When both the impactor and the helmet shell were equipped with add-ons, reductions in linear and rotational accelerations were greater
Balanced Organization Designed for easy packing and quick gear grabsideal for transparent carry-on or dive gear division
It has a lowstep frame that makes it easy to mount and dismount, disc brakes that provide stopping power in any weather, and wide tires for extra stability
The idea being that the rotational torque applied to the outer helmet isn't transferred to your head in the event of crash
