[Learn More Here](https://kavhelmets.com/pages/the-process) Engineered for Speed, Built for the Real World Rhoan stands among the fastest helmets on the market, within 0.001 CDA, or ~1 watt at 40km/h—while delivering airflow, cooling, and comfort they can’t touch. Award-Winning Safety The Rhoan earned a 5-Star Virginia Tech Safety Rating through a ground-up reengineering of impact protection. At its core is our Hex Honeycomb Structure 2™ — a dual-density, 3D-printed lattice with independent hexagonal cells that deform asymmetrically to manage both linear and rotational energy. This architecture eliminates the need for traditional slip-plane systems by integrating rotational management directly into the structure, resulting in lower weight, improved ventilation, and uncompromised real-world performance. Cooler Core = More Power A 1°C rise in core temperature can reduce performance by up to 1.5%. The Rhoan is made from our proprietary PolyCarbon Composite™ that wicks heat 8x better and cools 2x faster than standard EPS foam—helping you delay thermal fade and hold watts longer. Optimized Airflow, Inside and Out The Air Fit Suspension and HexFlow™ Rear Exhaust work together to create full-helmet airflow. Heat is actively pulled away from your scalp—maintaining focus, control, and comfort, even on the hottest days. Smart Structure for Thermal Regulation Our next-gen Hex Honeycomb Structure 2™ acts as a thermal scaffold, channeling air through its open-cell design. It improves both impact absorption and heat dissipation without adding weight or bulk. Made in the USA Designed and manufactured in the USA using a net zero production process—delivering innovation, sustainability, and performance without compromise. What People Are Saying Very light and comfortable. I like the style and it was a very easy process to get fitted for this unique helmet. Richard. \_ 12/30/24 KAV stands by their products. In October, I had a cochlear implant, which changed the dimensions of my fit. KAV offered me a significant discount, provided a re-fit to accommodate my implant. Not only an excellent NOVA product, but outstanding customer service. Lane. \_ 12/18/24 It feels great throughout long rides and I even forgot to take it off after a ride recently! Do yourself a favor and order the perfect helmet - for comfort, safety, design, weight, and ventilation! Claudia G. \_ 11/06/24 This is the best helmet I’ve ever owned. No more adjusting the back closure and looking in the mirror to make sure it is not crooked on my head. Fits perfectly every time. John M. \_ 10/30/24 I had the amazing opportunity to be able to purchase one of their 3-D printed helmets with custom coloring. Alex Y. \_ 10/29/24 ### Aerodynamics That Actively Cool Engineered to harness the Venturi effect, the HexFlow™ Rear Exhaust accelerates air as it exits the helmet—pulling heat and moisture away from your head with every effort. Working in tandem, the Air Fit Suspension System lifts the helmet off your scalp to create uninterrupted airflow throughout. The result: better cooling, reduced core temperature, and sustained power when it matters most. ### 2x Larger Front Vents Strategically placed lower on the brow to funnel cooling air directly to the forehead, where thermoregulation is most effective. It’s not just about vent size—it's about vent placement that works with your physiology. ### A Fit That Breathes Our Air Fit Suspension System™ suspends the helmet off the head, eliminating pressure points and maximizing ventilation. This all-around airflow helps reduce hot spots and maintain a cooler, more stable core temperature throughout your ride. ### 5-Star Virginia Tech Safety Rating The Rhoan’s Hex Honeycomb Structure 2™ uses a dual-density, 3D-printed design that adapts independently on impact — absorbing energy from both direct hits and rotational forces. This advanced structure eliminates the need for bulky add-ons, reducing weight while enhancing real-world safety and comfort. ### Lock In. Ride On. Redesigned and 3D printed for real-world use, the new sunglass ports make it easy to stow your shades mid-ride—and keep them secure, even over rough terrain. No slipping. No rattling. Just smart, ride-ready utility. 1 / 5 GET OUT THERE™ ## SPEED MATTERS EVERYWHERE ## HOW WE COMPARE The future of personalized performance 108 Measurements, 1 Perfect Fit Optimized for Rotational & Linear Forces Virginia Tech 5 Star + 50% Above CPSC Safety Standards Crash Replacement Warranty Proudly Crafted in the USA KAV3D PRINTED HELMETS 100% 5 Years TRADITIONAL EPS FOAM HELMETS 35% 2 Years ## Frequently Asked Questions How does the custom fit work and what is involved?

The Rhoan earned a 5-Star Virginia Tech Safety Rating through a ground-up reengineering of impact protection. This architecture eliminates the need for traditional slip-plane systems like MIPS, by integrating rotational management directly into the structure, resulting in lower weight, improved ventilation, and uncompromised real-world performance. What is the difference between the Rhoan & Nova helmets? Features unique to the new Rhoan Helmet: •The Rhoan is 20% lighter than the Nova • 6mm on average narrower than the Nova • The interior has been redesigned with our all new internal Air Fit Suspension and HexFlow™ Rear Exhaust, which work together to create full-helmet airflow. Heat is actively pulled away from your scalp—maintaining focus, control, and comfort, even on the hottest days. How much do your helmets weigh? Every helmet is custom made so even for the same circumference, your head shape can change the size by +/- 20 grams. However someone who is in the middle of medium (~57.5 cm circumference) can expect their KAV Rhoan helmet to weigh 300grams. Why Hex & Why it Matters. Our helmets are engineered with our proprietary Hex Honeycomb Structure 2™ which has the most efficient energy absorption to weight ratio or crumple zone design to redistribute energy & force upon impact. What if I want to wear a cap or cut my hair, will my custom fit cycling helmet still fit? Yes, the Rhoan features a rear ratchet mechanism built into them that allows 8-10mm of travel ensuring both a snug fit as well as giving your custom helmet a bit of play to account for the winter season or a new haircut. "This is the best helmet I’ve ever owned. Well worth the wait. Hardest part was adjusting the strap placement around my ears. Now all I have to do is put it on my head and clip the strap. No more adjusting the back closure and looking in the mirror to make sure it is not crooked on my head. Fits perfectly every time."

Heaps better than the Nova.** It's really, really nice. I wish I could give it 4. 5 stars. If you had a Nova and didn't like it, give the Rhoan a shot. It's not that much lighter, but it FEELS way lighter. The dial fit is a total game changer. A nice bonus is the brow of the helmet sticks out enough that it's almost a mini visor...
