Remember the Aeroshell? Lazer’s innovative, if simple, plastic helmet fairings have allowed users to convert ventilated models to aero alternatives for several years. It’s a smart accessory adding versatility for users, but with no way to stow it, you better make peace with the level of head sweat you committed to at the start of the ride.
Enter the Bullet 2.0, the latest iteration of a creative, aero-profile Lazer lid that allows quick and easy toggling of the closure of its front-facing vents. Riders can keep things breezy when desiring better comfort and close the vents for better aerodynamics when needed, all without the need for some additional accessory. How does this interesting approach perform in the real world, and how does the 2.0 improve on the original?
First, the specs. Lazer reports the Bullet 2.0 weights 315 grams in size small. The helmet ships with several swappable panels (more on that later) and large Zeiss lens that is specific to this model. Lazer built a rear-facing red LED into the ratcheting retention mechanism for the Bullet 2.0, and finally, there’s a branded cloth bag with a drawstring to keep everything together. Prices vary, but this tester found costs of about $270 online.
The headlining feature of this helmet is clearly the ability to change modes on the fly. The default front vent is more complex than it might appear to a casual observer – there are four “fins” in the sliding mechanism that direct air over the head and pivot to sit flush while closed. The whole system is easy to operate, though this tester found it tricky to apply enough force while in motion in the saddle without much to grab on to. Still, it’s easy, and it works.
It’s difficult for a layman rider to comment on the aerodynamic benefits of “closed” mode, but Lazer offers some figures. If users swap for the alternative panels included with the helmet, turning the transforming vents into a flat surface, the Bullet 2.0 unlocks seven watts of power at about 35 miles per hour. Lazer says this equates to about eight meters in the last kilometer of racing, and for those out there who have lost races by millimeters, it’s a compelling statistic.
Some reviews of Lazer’s first version of the Bullet complained of inadequate airflow even while vents were open, but this was no issue for this tester with the 2.0 version, even on hot summer days at Portland Oregon’s Alpenrose Velodrome. The 2.0 has deeper channels in the helmet than the original version, and a new top-of-the-helmet vent Lazer calls the Venturi Cap is meant to accelerate the air flowing over the top of the head. Even with the solid panels installed, users can still open up the front to reveal a decently large port.
The fit is extremely comfortable – this tester has been using Lazer helmets for years, and true to his previous experience, the Bullet 2.0 applies even pressure around the head. Lazer secures the helmet using what it calls the “Advanced Turnfit System,” a back-of-the-head dial reminiscent of other helmet brands. This tester wondered whether the pivot from the Rollsys system Lazer uses for its other high-end lids would impact fit, but while the Advanced Turnfit System is bulkier in appearance, it is comfortable – and the build-in LED is a nice touch.
The Bullet is noticeably heavier than this tester’s typical high-end lid, about 100 grams heavier. But weight isn’t everything – the old adage was that aero came at a weight penalty, and for weight weenies, Lazer’s own Z1 is advertised at 190 grams for size small. It’s all relative, as this tester’s go-to helmet for many track events is Lazer’s Victor, a space helmet that exceeds 400 grams.
The Zeiss lens for the bullet is a really great touch. Lazer argues that the lens improves the aerodynamics of the helmet, and it fits flush, via magnets, to create a smooth and rounded profile facing into the wind. The optics of the lens are excellent, and there are zero contact points on the face. A single magnet exists at the rear of the helmet to stow the lens when desired.
One minor issue for this tester was that the Bullet would seem to tilt forward over time in an aero position and the un-cushioned bridge of the lens would wind up resting on the nose – I wonder whether a lightweight pad might make for a nice contingency, though perhaps it wouldn’t be worth it in terms of aerodynamics and weight. For those who prefer to use different shades, I had no issues with compatibility with long-armed eyewear such as the Oakley Radar.
Lazer manufactures a host of helmet accessories, and the Bullet is compatible with a heart-rate monitor and an alarm to remind riders to keep their head in the proper position.
So what was life like with the Bullet 2.0 this summer? For this tester, the Bullet addressed a very annoying problem at the velodrome – carrying two helmets. This tester would traditionally use an airier lid for warmups on the track, and only break out the space helmet for time trials. The ability to lean on an all-in-one helmet was a great convenience.
For the versatile competitive cyclist, the Bullet is just a great everyday lid. Keep it open for road climbs and training rides, close it down for criteriums, swap for the solid panels for time trials. With the Zeiss lens and the interchangeable panels, this is a very versatile helmet and a great way to buy some free speed.
