REVIEW: Lazer Bullet 2.0

The Lazer Bullet 2.0 gives triathletes the ability to monitor ventilation without compromising aerodynamics.

In January, Lazer released their Bullet 2.0, an upgrade to its predecessor – the Lazer Bullet. The new helmet improves on the Bullet’s performance by offering better cooling and increased aerodynamics.

Using Bullet’s unique construction, a sliding louvre-like honeycomb vent, the Bullet 2.0 vents can be kept closed for maximum aero gains or opened on-the-fly for additional venting. Known as Lazer’s Airslide system, this feature comes in handy regardless of your preferred triathlon distance.

For someone like myself, who sweats a lot, the traditional aero road helmet can present some discomforts, especially when competing in long-course triathlons. There have been numerous times when I’ve selected a traditional aero helmet, and wished I had more ventilation. Without having to have two separate helmets (ventilation and aero), the Lazer Bullet 2.0 gives triathletes the ability to monitor ventilation without compromising aerodynamics.

With more aggressive internal air channels that further improve airflow, the Lazer Bullet 2.0 gives more ventilation than most aero road helmets. Inspired by Formula 1, the Venturi rear top cap allows additional airflow throughout the helmet for added comfort when riding. Lazer claims the Bullet 2.0 has a thermal heat loss of  11% over the original Bullet and 4% versus the Z1.

Besides the obvious ventilation and aerodynamic performance gains of the Lazer Bullet 2.0, I was impressed with how comfortable the helmet was. Featuring a dial-adjustable fit system with MIPS construction, I was easily able to get the perfect fit for my head and adjust on the fly.

Included with the Lazer Bullet 2.0 is a magnetic lens system. If like me, a lens isn’t your thing, you can easily remove the lens. Which can be discarded or stowed at the back of the helmet.

With warmer days on the rise, the versatility of the Lazer Bullet 2.0 will be much appreciated this summer. The Bullet 2.0 with MIPS has an MSRP of $380.
