A Step-by-Step Guide to Sizing and Adjusting Lazer Helmets
A well-fitting helmet is one you barely notice, yet it plays a critical role in comfort, confidence, and protection on every ride. Lazer helmets are designed to fit a wide range of head sizes and shapes, thanks to multiple shell sizes and purpose-built retention systems.
Use the guide below to dial in the ideal helmet fit, so your helmet stays comfortable, secure, and ready to protect when it matters most.
How to Measure Your Head for a Lazer Bicycle Helmet
To find the right helmet size, start by measuring the circumference of your head. Place two fingers (roughly two centimeters) above your eyebrows and wrap a tailor’s tape around your head at that height. A tailor’s tape works best, but a standard tape measure, string, or shoelace will do the trick.
Record the measurement, then measure again to double-check. As the saying goes, “Measure twice, order once.”
How to Select the Right Lazer Helmet Size
Once you have your head measurement, consult the size chart for the specific helmet model on the Lazer website. Choose the size that aligns with your measurement.
Thanks to Lazer’s micro-adjustable fit systems, each helmet size accommodates a wide range of head shapes. If you fall between two sizes, Lazer recommends choosing the smaller size to ensure a more secure and stable fit once the retention system is adjusted.
Fine-Tuning Fit with Lazer’s Retention Systems
Lazer helmets are designed to fit most riders straight out of the box, with retention systems that allow precise fine-tuning. Each helmet model uses one of four primary head basket and dial adjustment designs, carefully chosen to match the helmet’s intended use.
These systems distribute pressure evenly around the circumference of the head, minimizing pressure points while keeping the helmet securely in place. The result is a customizable, comfortable fit that allows the helmet to perform at its highest level of protection.
Since introducing the Rollsys retention system in 2005, Lazer has continually refined its proprietary fit technologies. Today, Lazer’s lineup of road, mountain, commuter, and kids’ helmets features four distinct retention designs, each engineered for the ideal balance of comfort, security, and adjustability.
Unlike linear fit systems that apply pressure in limited areas, Lazer’s retention designs cradle the head with a fine-tunable, 360-degree fit that feels secure without feeling restrictive.
What Are Helmet Head Baskets Made Of?
Early Lazer head baskets used a combination of plastics and metal components. Over time, Lazer eliminated metal entirely, replacing steel cables with purpose-built, specifically shaped nylon materials.
This shift improves durability, longevity, and comfort while allowing smoother adjustment and a more secure fit over the life of the helmet.
How Different Head Baskets Support Different Riding Styles
Just as helmet shells and padding vary by riding discipline, head baskets are also fine-tuned to meet the demands of different types of cycling.
-
Mountain bike helmets, such as the Jackal KinetiCore, feature deeper, more robust head baskets to support extended coverage and added material. This design helps keep the helmet stable while navigating rock gardens, landing jumps, or riding aggressive terrain. Riders who mount accessories like lights or action cameras will also appreciate the added stability.
-
Commuter and sport road helmets, including models like the Codax KinetiCore, use similarly supportive head baskets to manage added weight from features like integrated lights and increased coverage.
-
Road and gravel helmets, such as the Vento KinetiCore and Strada KinetiCore, use lighter, more streamlined head baskets. With less overall mass to manage, these lower-profile designs secure the helmet comfortably while allowing natural head movement, whether checking traffic, attacking a climb, or grabbing a quick drink.
Use Pad Kits to Fine-Tune Comfort
Lazer helmets include removable padding kits that make it easy to personalize comfort. Pads attach using small Velcro tabs inside the helmet and can be repositioned as needed to accommodate unique head shapes.
Padding adjustments affect comfort only, not protection. Helmets are tested without pads installed, so moving or adding pads won’t compromise impact protection. Additional pad kits can also be purchased and added in areas where extra cushioning is needed.
KinetiCore Fit and Protection
A helmet that fits right is just the first step toward better protection. Pair this with Lazer KinetiCore technology, and you get a comfortable, secure helmet designed to protect against linear and rotational impacts in the event of a crash.
KinetiCore was designed as part of the helmet itself, rather than an add-on extra piece of plastic that can lead to an uncomfortable fit. Instead, KinetiCore is built directly into the helmet’s EPS foam using precisely engineered crumple zones. These controlled deformation blocks compress and shear on impact to help redirect rotational forces away from the brain, reducing the risk of concussion. All without affecting fit and comfort.
Lazer’s 60-Day Satisfaction Guarantee
Sometimes a helmet feels perfect on paper but not quite right once it’s on your head. That’s why Lazer offers a 60-day satisfaction guarantee. If your new helmet doesn’t fit as expected, you can exchange or return it within 60 days, no hassle required.
