Description

It should come as no revelation that over the course of a triathlon, your body will be tested. Simply put, you need every advantage that you can get, and when you've exhausted the channels of apparel and lightweight bicycle components, it's time that you take a look at your aerodynamic position. An aero piece like the Lazer Tardiz Helmet can literally shave your time off of the clock. Don't believe us? Ask Julie Dibens if the Tardiz played a role in her shattering of the bicycle course record at Kona? We think that you already know the answer.

Let's get down to brass tacks -- you're wearing an aero helmet for aerodynamics. So, you're probably wondering, 'what is the Tardiz helmet going to do for me?' Luckily, that's an easy question to answer. Lazer designed the Tardiz around what it calls Dual Layer Aerodynamics. Looking at the profile of the Tardiz, you'll notice that the construction takes on two different textures -- smooth and glossy at the front, top, and sides, and dimpled at the rear tail. Two textures are used in order to treat the air differently, depending on where the flow comes into contact with the surface of the helmet. So, the smooth texture moves the flow back to the dimpled tail. The dimples, like that of a golf ball, creates a slight turbulence directly above the surface called an artificial boundary layer. This layer forces the laminar boundary layer to become turbulent, which enables airflow to remain attached over more of the helmet for a longer period of time, thus providing a lower level of integrated drag. The drag that dimples creates is also called skin friction drag, and although it becomes increased, pressure drag (which is ten times higher than skin friction) is thoroughly decreased.

For retention and security, the Tardiz features Lazer's Rollsys retention system. The patented Rollsys is a fully integrated mechanism that completely surrounds the head. To dial in the fit, you simply turn the smooth thumb wheel, located at the top of the helmet. Even better, Rollsys tightens symmetrically, without pressure points, for a total blend of comfort and security. For the chinstrap, Lazer included its revolutionary Magic Buckle. Abandoning the fidgety, traditional clasp system, the Magic Buckle is a magnetic clasp system that uses two strong magnets to pull the clasp together and to keep it fastened.

Lazer has also taken great steps to eliminate another common ailment to triathlon helmets -- overheating. The Tardiz has six points of ventilation, three in the front and three in the rear. This system keeps a steady airflow over the head, constantly cooling and evaporating moisture. Additionally, Lazer included its Aqua Vent. Located at the top, rear of the Tardiz, the Aqua Vent is essentially a port that the rider can pour water into from their bottle. Impressively, Lazer has also incorporated a molded, internal distribution channel, emanating from the port. So, you'll experience the evaporative benefit without getting sweaty water into your eyes.

And on the issue of sweat, the Tardiz features Lazer's antimicrobial, odor-fighting, and temperature-regulating X-static pads that stretch from the forehead back to above the ears. X-static pad in tow, your helmet will always be fresh and clean. Also, the pads have been positioned as to allow the easy placement of traditional sunglasses. However, the helmet is established for an integrated lens system.

The Lazer Helmet is available in the sizes Medium and Large and in the colors Cyan/white and Red/white.

Exceptional for tri's and tt's

  • Familiarity: I've put it through the wringer

I started doing triathlons a couple years ago and had always just used my regular road helmet. This year I upgraded to a TT bike and decided it was time to upgrade the helmet as well.

I did quite a bit of research mainly between this and the Giro options. After making my choice I have to say(having owned Giro helmets) I am more than happy with my purchase. Key features that I have found helpful are the three front vents that allow air to easily move through the helmet and out the back, the "golf ball style" tail really cuts down on noise, and my favorite being the gel rim around the front that completely blocks sweat from dripping down into your glasses. My other helmets that have padding up front tend to fill up with sweat quickly and when the wind changes just drip and blow into my eyes and glasses. The only thing I found awkward and it took me a bit to get used to was how high up on the forehead the helmets sits. This is not a bad thing, just took time to get the fit right.

So quick recap: Great ventilation, almost no wind noise, perfect sweat "discarding", love the magnetic clip/unclip, and a great price point! I'd recommend this helmet to anyone doing triathlons from sprint to full distances as well as TT's.
