Lazer's second iteration of the Bullet aero helmet is here

New Bullet 2.0 retains sliding vent, gains magnetic visor and claims significant aero improvements

Lazer has released the Bullet 2.0 — an updated version of its all-round aero helmet at the Tour Down Under.

The new helmet retains the signature adjustable ‘Airslide’ central vent of the first generation model and gains a magnetic clip on visor that is claimed to offer significant aero savings.

The Bullet 2.0 debuted upon the domes of Team Sunweb and Team Jump-Visma at the Tour Down Under Classic, the precursor to the WorldTour opener on Tuesday. Sponsored teams will be using the helmet alongside the Z1 for the rest of the season.

Compared to a Lazer Z1 — an all-round, non-aero helmet — the Bullet 2.0 is claimed to offer 7 watts less resistance at (an oddly specific and oddly fast) 58.68 km/h with the vent closed and the visor fitted. That amounts to an advantage of approximately 8 meters over a kilometer.

Its removable visor is held in place with two magnets located on the underside of the brim of the helmet. When not in use, the visor can be stowed away on a single centrally located magnet on the rear centre of the helmet.

The internal channelling of the helmet has also been updated in an aim to improve the cooling qualities of the helmet. These updates are claimed to make the helmet 11 percent cooler than the previous generation of the Bullet and 4 percent cooler than the Z1.

The helmet is compatible with Lazer’s LifeBEAM system — a heart rate monitoring module that can plug into the helmet — as well as the Belgian brand’s inclination sensor. The latter detects the position of your helmet and can advise on whether it is in an aero-optimised position. A MIPS-equipped version of the helmet is also available.

The helmet will retail for AU$449 (international pricing TBC) with availability TBC.
