Lazer Bullet helmet
he development of performance helmets changed forever when Mark Cavendish won the 2011 World Championships wearing a snap-on aeroshell over his helmet. It served as the catalyst for the ‘aero-road’ niche – helmets not quite as slippery as a full TT set-up but a lot faster than conventional lids.
After several seasons where it simply offered a removable cover to make its top-tier Z1 more aerodynamic, Lazer has joined the fray in earnest with a dedicated aero-road design – the Bullet.
It was developed primarily to answer calls from Lotto Soudal’s Andre Greipel for something aerodynamically superior to the Z1. The helmet has a slatted central channel that can be pushed open or shut with the ‘Air Slide’ – a perforated, sliding panel – dependent on whether aerodynamics or ventilation is the priority.
‘The Bullet saves 16 seconds over 40km compared to the Z1 with its ventilation system closed, yet with it open enough air can circulate to prevent our riders from overheating before the sprint,’ says Oli Collins, senior Lazer brand manager at its UK distributor Madison.
The time saving the Bullet claims to offer would be considerable over the length of a Tour stage, yet Greipel finished second on the Champs-élysées this year… maybe he forgot to close the Air Slide.
