Description
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.

Reviews
I have worn a lot of different helmets, but this is by far the most comfortable one I have ever owned. It is light, fits great, and ventilates extremely well. I added the high vis aero shell for days where visibility is important, but the aero shell will reduce the air flow somewhat. I rode with this helmet over 4000 miles this year across the U.S. and would certainly recommend this as a first choice touring helmet.
The retention system just broke. That thin little bit of plastic visible in the image on the bottom left of the helmet.
I rode it from 02/2021 to today (09/2023) as my primary road, gravel, and xcmtb helmet. Just a guess, but I'd put it at ~1,000hrs of use. I was very pleased with how cool my head stayed compared to the Giro Savant I had used previously, especially while climbing on those super hot summer days. Even on the mtb, when climbing is half the speed or less than a road climb, I stayed cool.
Summer is over so I have replaced my broken G1 MIPS with a Lazer Vento. I won't think twice about buying another G1 next summer if the Vento cooks my brain. $200 is still a lot to a lot of people, myself included. However, the cliche phrase about only getting one head is still true no matter how hard we roll our eyes at hearing it. Two c-notes for the best protection ain't shizznit.
My Lazer z1 needed to be replaced and served me well. Decided to upgrade to the G1. Keep having to readjust during long rides as the rear of the helmet is causing some pain. Minimal difference in weight in size medium so I wish I had not switched.
I really want to like this helmet. Great fit. light weight and looks cool. Highly rated by the Va Tech Helmet Lab. Like a few other reviewers have pointed out, it is frustrating to unhook the clasp on this helmet. Suggest you try before you buy.
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.
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.
These are a really light weight helmet and comfortable, don't care for the clasps, bought matching helmets for my wife and I and she has a real hard time getting the clasp to release, that I have to help on occasion.
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.
Ride recumbent with taller setback, the adjustment on top of helmet more effective than models with adj. at base of back of helmet. Very satisfied.
Most comfortable helmet I have owned. I've had Bell, Gyro, Smith and Oakley but the Lazer G1 MIPS seems to be the best for my head. I got it on sale for a great price at BTD. It also offers great protection in a crash. I found out that Lazer has a great crash replacement policy too. I sent Lazer a picture of the damaged helmet and got 50% off a new helmet with 2 days.
I replaced my old Giro Aeon with this. The Lazer fits well and the retention mechanism seems way better and sturdier. Ventilation is very good. Catch it on sale it is a really good value for a high end helmet.
If you are between sizes, I would size DOWN. The size chart recommends sizing up. In my case I ordered Large and it was way too big. I exchanged for Medium and it's great. Fortunately, this item qualifies for easy and free return shipping on exchanges. Awesome policy, Bike Tires Direct!
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.
It's a nice, lightweight helmet. Fits my head well.
Best of luck finding replacement pads for under the helmet...kind of frustrating that parts for a $250.00 helmet aren't available.
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.
I am totally happy with my new G1 helmet. It feels as everyone says, incredibly light in weight, perfect fit, and extremely well ventilated. I was easily able to fit the side ear straps, and they didn't move, or loosen at all even after hours of riding. And I've really enjoyed using the ARS top of helmet fit system. Using it is so easy, (I just start with it loose before each ride, then tighten it down), and after fitting the chin strap, the helmet feels totally secure. And the fact that is has the 5 start safety rating makes it even better.
Although my glasses don't fit as close to the helmet as some others, I turn my glasses upside down, and load them in using the biggest, low vents and they stay securely and firmly, out of the field of vision and ready for use. Awesome all the way around!
As usual, continued thanks to BikeTiresDirect for the best in customer svc, selection, and price!
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.
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.
