Leatt 4.0 V21.1 Adult MTB Cycling Helmet

Product Information

The chinbar attaches to the main helmet using magnetic plugs. We found it a bit of a struggle to locate the two with the helmet on, and a bit of a squeeze to get over your head with the chinbar installed. But when combined the whole helmet feels reassuringly solid. We loved the BOA retention adjustment, and it’s great to have MIPs integration to protect against rotational injuries. Overall, the Met Parachute proved to be a well-designed convertible helmet that does everything to a good level. One of the big plus points with the Switchblade is the size of the chin bar. Andy Lloyd / Immediate Media One of the lightest fully DH-certified full-face helmets we’ve ever tested, the IXS Trigger FF makes a great choice if you prioritise freedom of movement and breathability. Only the Dainese Linea 01 made less of an impression on our scales. We were (literally) blown away by the ventilation on offer from the Trigger. In fact we’d say that it actually runs cooler than some open-face helmets, thanks to well-designed channels over the scalp. We even found it a bit chilly on winter bike park laps! Like the Leatt, it does without a ratchet and relies solely on padding to provide a secure fit. Largley, the fit is good without any noted discomfort save for the cheek pads. They're shaped like a Z, and while it's not a massive issue, I did find that they weren't cut low enough to fit underneath my ear. It wasn't a big issue, but on big climbs that would take several hours into the alpine I would often just unclip them at their lower point and rotate them down. It should be said that I haven't tried on the extra large, but the helmet does fit in all other regards and I don't necessarily want anything bigger. There are no major flaws present in the Enduro 4.0, but a few minor issues are worth pointing out: The goggle strap will end up at least partially covering a certain number of vents, always a pet peeve of ours. The chin strap is very long, absurdly so it seems to us. It does not really create an actual problem but you do end up with a lot of excess strap to manage. There are also no adjustable splitters on the chin strap, which means that you can’t tune it to sit perfectly around your ears if the standard position is problematic for your particular head shape. All told these are very minor issues though. Long Term Durability

With a vast array of bike helmet brands available including Giro, Fox Racing, Endura and more, our selection of bike helmets ensures there is something for everyone. Reasons to buy: Incredibly light weight, high protection rating, plenty of ventilation, flexible adjustable visor, RECCO Lightweight, ventilated full face helmets are a regular sight at races and trails these days, however helmets with removable chin bars divide opinion between riders. Are they the best of both worlds, two helmets in one? Or are they just an over-complicated compromise? We’ve worn just about every helmet Leatt has made in the last few years from their trail bike helmets to dirt bike helmets and the DBX 4.0 is one of our favorites and most comfortable yet. Leatt has done a good job with the DBX 4.0 and we’d say it’s one of our top recommended options for truly aggressive riders who put protection over ventilation or want something geared slightly more towards DH than XC. The DBX 4.0 is sturdy enough to where we’d feel comfortable hitting the occasional bike park day on a big bike but is light and breathable enough for some burly ebike days. At 850grams it’s definitely not going to compete with the Bell Super or Kali Invader, but in our opinion, it’s not really supposed to. Those are helmets we’d suggest for timid trail riders looking to protect their teeth or aggressive trail riders who ride in hot climates and want a little peace of mind without a major penalty in the weight and ventilation department.

Leatt MTB 4.0: do-it-all helmet that has you covered for both trail and downhill runs 3. Leatt MTB Enduro 4.0 Top notch dual-purpose, convertible full-face helmet

This downhill-certified helmet uses a polymer shell construction. Within the shell, there is a generous amount of "impact foam" lining the shell. While higher-end helmets often use EPP foam or EPS foam, it is unclear what exactly "impact foam" is. That said, it bears a very strong resemblance to EPS/EPP foam found in most downhill helmets. The foam layer is hidden by the padded, removable inner liner.Every cyclist is unique, and Leatt understands that. That's why their helmets come with adjustable fit systems, allowing you to customize the fit according to your preferences. Whether you have a small or large head, you can easily find the perfect fit with these helmets, ensuring a secure and comfortable ride every time. Style and Durability Whether you need a mountain bike helmet, road bike helmet or the additional protection of a full-face bike helmet, we are here to help and have a range of adult cycle helmets to protect you when you are out and about. The snug fit makes for a confident feel and, with the large adjuster dial cinched up, we had no issues with it moving around on really rough trails. In open-face mode, it has the most head coverage, which, coupled with the MIPS liner, should keep you well protected. Reasons to buy: Downhill-certified, adjustable visor, new MIPS Integra Split system, excellent ventilation Whether you’re chasing split-second advantages in a race or honing your skills on uplift park days, there’s always the risk of a crash. No risk. No Reward. But thanks to the Impact foam of the Gravity 2.0 you have reliable head protection when it all goes a bit wrong. While this core soaks up and dissipates the forces from impacts to your head, the outer polymer shell provides structural strength and structural integrity in a crash. A winning combination.

If you live your mountain bike life in a blur and the speed and exhilaration of downhill riding is your passion, the MTB Gravity 2.0 Helmet is made for you.The only way in which an F1952 certified helmet will provide better protection for downhill riding is if it utilises a dual-density EPS liner. One with a high density for high-speed crashes and one with a lower density for slower-speeds. Obviously the addition of any impact tech (Turbine etc) will help for lower speed too. The Mainline is an excellent example of how the enduro racing discipline has helped develop the modern mountain bike helmet. Sure, full-face lids of yore always paid lip service to lower weight and decent ventilation, but in practice we’d always take them off when not descending. Inside there’s a smart retention system that’s easy to cinch open and closed for entry and egress. But the Bell Super Air R is not the easiest to transform between modes – it’s a job best done before you put the helmet on. While not the last word in protection, the Super Air R makes a great two-in-one product for trail and enduro riding.

If you live your mountain bike life in a blur and the speed and exhilaration of downhill riding is your passion, the MTB Gravity 2.0 Helmet is made for you. MIPs is an internal liner within the helmet that is designed to slide in the event of a crash, with the aim of reducing rotational motion of the brain. Rapid acceleration of the head can leave the brain lagging behind, which can cause brain damage, so MIPs is designed to allow the helmet to continue moving when it is involved in an oblique impact, rather than catching and forcing the head to spin. MIPs is not the only technology designed to reduce rotational injuries, but it’s certainly the most well known, with its distinctive yellow logo and plastic helmet liner. Many helmets now incorporate this technology, and while it carries a small cost premium, in our view it’s well worth the extra investment. Why do mountain bike helmets have peaks?When it comes to your safety on the bike, nothing should be left to chance. That's why Leatt full face helmets are a must-have for every cyclist. These helmets are designed with cutting-edge technology and uncompromising quality to keep you protected in all your cycling adventures. Unparalleled Protection We loved the original Fox Proframe when we tested it, mainly for the generous airflow that kept our lungs inflated and our head cool. This second generation model is heavier and more expensive, but gains several features that make it worth the extra weight and cost. One is the MIPS Integra Split protection, to reduce injury from rotational impacts, a convenient BOA dial for the tension fit system, and an adjustable angle visor. Met’s latest do-it-all helmet certainly isn’t cheap, but quality and finish is top notch and it feels well built, with or without the chinbar. It’s the best looking and functioning Parachute yet, and feels properly sturdy and Alpine-ready in full face mode. Combine this with a good-looking, unobtrusive open-face option, and it’s a very versatile combination.
