As the helmet sponsor of several pro teams, Lazer had been pushed by their rider to come up with an aero road helmet. One that vented more like a regular lid than an aero helmet. In response, Lazer developed the Bullet Helmet, in both Standard and Mips versions.
The design is not based on their iconic Z1. That’s a great helmet, but the profile was not optimal for aerodynamics. They wanted something smaller. So they scrapped the design and worked on something new. The Bullet sits closer to the head and is shaped by wind tunnel testing so that the side vents don’t slow you down an the tail is shortened and shrouds the back of the head. Lazer fans will notice that the Rollsys dial is no longer present on top of the helmet, but a more conventional dial is used in back to snug the secondary retention system.
