LAZER Tardiz 2 Triathalon Bike Helmet

I have a rather large head- and this was literally the only aero helmet that could fit properly, covering my ears and being aerodynamic. I've tried Louis Garneau and Giro as well - these didn't work.The only thing - make sure you try it on together with your sunglasses. There isn't much space inside, so thinner your sunglasses frame is - more comfortable it's going to be.

I competed in my first triathlon in April this year and wanted to get the marginal gain of an aero helmet compared to my standard road helmet.I have an older Transition triathlon bike and have a pretty low aero body position compared to some of the newer bikes. The tail of this helmet seems to stick up rather than provide a smooth flat transition into my back even with my head up as far as I can go.The wings covering my ears generate a lot of noise at speed. If I turn my head slightly to look behind, there is a whistle coming from the vent on top. I find the helmet to be quite warm compared to my road helmet and very uncomfortable compared to that helmet as well. I have ridden 56 mile training rides with the helmet to simulate a half-IM.Now, all that being said, this helmet does make me faster. I don’t have a power meter, so simply relying on Strava speed data, but on a typical 20-25 mile training ride, I seem to be nearly 1 mph faster. I was able to average 21.5 mph on the hilly 18 mile bike leg at the Pinehurst Sprint Triathlon, fastest in my age group. Since that race, I’ve used the helmet to set numerous PRs and probably 10 KOMs on local segments. So, yes, it is fast.

I had a high expectations after reading lots of positive reviews. The helmet arrived in a nice package, the boxing was impressive. The helmet is cool looking, if you want something stylish on a mantelpiece, you have your item. The problems were started when I started to ride. Adjusted appropriately based on the instructions received with the helmet and watch couple of videos on youtube, as I have experienced only with a Giro brand helmet. Failure after failure...When it was good fit on the back, my forehead was so uncomfortable, and vica-versa. After a 12 miles ride I switch back to my old Giro helmet, and decided to return. It was one of most uncomfortable piece of something ever on my head. It felt so unsafe, so disturbing, and ruined my ride completely...

excellent helmet, aerodynamic, made of high quality material, I highly recommend it and the size is normal, so if your size is L order L that will fit you perfectly like me.
