To Plot The Future, Lazer Tapped Into Its Past.

Shaving both letters and grams, the G1 road helmet has been reborn from the ashes of its predecessor, the Genesis, as Lazer's lightest bike helmet ever.

How did they do it? Start with the G1's hardshell construction, which is molded from rugged and durable EPS foam construction.

Running through it are 22 internal channels that afford ample venting, which Lazer says is actually 8% more cooling efficienct than wearing no helmet at all.

Resting on the crown of the G1 road helmet is an Advanced Rollsys retention dial, which pulls an internal cable circling the base close. The fit that results is snug and secure but without headache-inducing pressure points.

Industry-standard MIPS guards against rotational impact should you hit the deck (fingers crossed you don't), while a pair of padded inserts let you shave even more grams for race day or opt for comfort on training rides.

Create two helmets in one with the addition of Lazer's G1 specific aeroshell (sold separately), which simply snaps into place to protect vented areas from the elements.

Features

  • The lightest Lazer helmet ever - 230g (size small)
  • Advanced Rollsys fit system allows for easy horizontal and vertical adjustment
  • In-mold construction
  • 22 vents
  • Includes two sets of pads: race and comfort
  • Lazer Aeroshell compatible
  • MIPS provides increased protection against rotational impact
  • Developed in partnership with multiple UCI WorldTour Teams

Best Helmet I've Ever Owned
rating
by Brian
Cycling Enthusiast
Geneva, IL

This is the lightest, best ventilated, and most slippery (aero) helmet I've ever owned. My last few helmets were Giro Aeon models which are light, but this 'feels' even lighter. On hot summer days I notice my heads is not as hot with the Lazer G1 as it was with the Aeon. It really has a nice air flow...whether on the hoods or head down in the drops. I am getting used to the location of the retention device. It is simple enough for me. Tighten once, loosen at the end of a ride. For me there have been no problems with it loosening on its own during a ride. The straps, buckles and other components are much better than my Aeon. Because of the unique retention system, I suspect my wife will want one since it seems pony tail friendly. 5-stars for far.

It's not cheap, but many high end helmets aren't these days. I returned a POC Ventral helmet due to it's round head profile while I'm more an oval. This G1, and the halo adjustment fits me much more comfortably, and has the added bonus of being the best tested road helmet by the Virginia Tech Helmet Ratings.

It's relatively light, and does a decent job at floating on the head as opposed to feeling like it's molded to it. I've done many a 3+ hour ride with it so far, and have not had any pressure points, hot spots or anything. It has been relatively cool as the temps have started to climb, but I've only had it for the last month and a half so it hasn't seen a proper summer yet. The only thing I have found to be of any annoyance is that my hair tends to get caught up in the mips layer at the front and pulls a little when removing the helmet at the end of the ride. Other than that, I have nothing remotely bad to say.

It is a nice, light helmet. The MIPS feature is a plus. The back head cradle retention system does loosen. I have noticed this in other Lazer helmets too. I find myself having to tighten it often during a ride.

Nice helmet. I haven't had any loosing issues report by some folks. I did find the size large a little bigger than my Giro Synth. I always wear some form of summer or winter head covering under my helmets. Without wearing the head covering this helmet would be too big for me.

First time purchasing from this site and was pleasantly surprised. Speedy delivery and everything arrived perfect.

As for the helmet itself, an absolute steal at the sales price - very lightweight, well-ventilated...unfortunately I never got to take it on a ride. I was right on the border of M and L and I went with L and alas...a bit too big for my head.

Really light. A little bit big.
rating
by Guidon
portland, OR

When it came time to replace my helmet, I wanted a light weight MIPS helmet. I decided on the Laser because you can get a snap-on cover for cold & nasty weather.

It is certainly light ( even with the optional cover).

It has a unique dial on top to adjust the fit. Unlike most helmets that clamp the occipital area, this one snugs to your head higher up. You may or may not like this feature. I always wear a medium, and I have to crank this one all the way down to fit my head, so it runs a bit big.

I was looking for an alternative to my super safe, super bulbous, super ventilated Poc Ventral Air Spin. I read some reviews that the Lazer MIPS was not well ventilated. I ride in Houston and find it very comparable to the Poc. It is lighter weight and smaller form factor and near the top of the Va Tech rankings. Highly recommended.

Great fit for an oval head

I haven't had a chance to test this item for its intended purpose and hope I never do. Should that event happen, though, I'm very comforted to know that this helmet actually fits my head. I've always had issues with helmets as I have a long oval head shape. Most helmets are either too wide with lots of side-to-side play or don't properly sit on my head. I was pleased to find the Z1 MIPS as the fit is almost perfect and the style looks great.

One thing to note which is super-important:

If you can't get the retention strap to tighten enough then turn the helmet over and pull back the MIPS liner where the retention mechanism attaches to the center back of the helmet. You will find a single silver screw that attaches the retention harness to a plastic strap that attaches to the helmet itself. On mine there's a sticker that points out this location, but I know it's not present on all of them. Loosen that screw and you can slide the retention harness so that it sits lower on your head. On mine I slid it out as far as it would go (don't forget to re-tighten the screw) and now I can tighten the harness down more than enough.

I have had this helmet now for about 2 months. I like it very much, it is light and well ventilated as advertised. The only negative is the sizing. I measured my head circumference about 6 times, and came within a few millimeters of 59 cm each time. Given that, I ordered a L, (58-61 cm). It is way to big, and I should have ordered a medium (not available at the time, as wasn't the M/L), as it projects about 2" (5cm) behind my actual head. . Fortunately, the Rollsys fit system snugs it down fine. Must look a bit weird to my riding buddies, but it works ok.

Just returned from a bike trip to N. Cascades in Washington. Wore this helmet in high heat 90s for 40-50miles a day. It goes on/off easy, is light weight, and the spin wheel on top of helmet rather than rear is quite nice. I wear a ponytail and no problem with fit. One caveat: i measure at 55cm so ordered a medium (which starts at 55cm). This was way too large, could not tighten it enough and had to exchange for a small which is perfect. I think if you have a very round head the bigger size might be needed but my head is more oval. P.S. exchange was super easy, no need to fill any paperwork, quick email and they sent me a fed ex label. Very pleased with this company.

I wanted to like this helmet... I wanted to love this helmet... adorned on pro riders it looks cool, it gets great safety ratings, and it's the flagship offering from a legendary brand, so it has to be good, right? Well...it has what I consider to be a really protruding "bill" on the front of the helmet--it really sticks out there compared to the low-profile front-end of my Lazer Z1. A few others have pointed this out as well. So really nice helmet but aesthetically, just not my thing.

It was time to replace my old road helmet and after some careful research on safety, weight and fitting - this Lazer G1 is everything I was looking for. Love the fit and keeps my head cooler on hotter days. For winter I plan on ordering the Aeroshell to cover the vents. Most of my rides are 40 - 65+ miles 3 times a week and this is by far the most comfortable helmet I have ever worn. A bit pricey, however in this case you really get what you pay for!

A brief history of my helmet wearing: I'd always worn Giro helmets up until six or seven years ago when they first introduced their MIPS helmet. Sadly, that bad boy didn't fit at all as the M was too large and loose and the S was too small and tight. I then changed to a Kask Vertigo in a M but it was actually too large, was insufficiently well-ventilated, and sweat ran into my eyes. So then I moved to the Kask Protone in a size S. I loved Protone's aesthetics but, man, talk about poorly ventilated. Sheesh! So, onto the Lazer, which is simply AWESOME! Super lightweight, uber adjustable, and the best ventilated helmet I have EVER worn. Seriously, it had been so long since I'd worn a truly well-ventilated lid, that I'd actually forgotten how pleasant it is not to have sweat dripping into your eyes. This has become, now, my favorite helmet ever.
