UNBREAKABLE SPIRITS
When your body says stop, your mind keeps going. Naii was born for those moments when all you can do is grit your teeth and keep pushing. Designed for riders who race events like The Traka, Badlands or Huelva Extrema. For those who train every day with a clear goal: go further, go stronger, go faster.
In these races, there’s no room for mistakes. You need a bike that always responds. That turns every pedal stroke into traction. That absorbs what you don’t see on the trail and lets you focus on one thing: moving forward. Naii is that ally. With it, your energy isn’t wasted—it’s turned into momentum.
ROAD SOUL,
GRAVEL HEART
Naii is born from the Belador, our fastest road platform. It inherits its aerodynamics, structural stiffness, and performance spirit. But we didn’t stop there: we adapted it for more demanding gravel, increasing tire clearance, adjusting the stack, and adding greater absorption.
The result is a gravel bike with the soul of a race machine, but that flows with confidence across broken terrain, fast tracks, technical trails, and long unpaved routes. Naii is fast, sharp, and relentlessly efficient.

SOFTEX™ TECHNOLOGY
MORE COMFORT WITHOUT LOSING A SINGLE WATT
Softex™ is more than a comfort solution. It’s a technology that redefines performance on ultra-distance rides. Exclusive to Berria, it’s designed for riders who know gravel races aren’t won by strength alone—they’re won by holding on longer, staying steady, and pushing through when your body screams stop.
Softex™ protects your body, supports your mind, and extends your performance.
Because when you’re less tired, you make better choices.
And in long races, that could mean the difference between finishing… or winning.
Softex System
The system is made of two key elements: the Tibia Aero seatpost and the rear triangle, both designed with controlled flex for a dual-phase absorption.
This is not a suspension system
it’s more efficient for competitive gravel. It adds no weight or energy loss, but completely changes your ride. The result: improved traction, more rear-end stability, and total control on every curve, climb, and fast descent.
Phase one: micro-vibrations
On uneven but not brutal terrain—loose gravel, small bumps, or surface transitions—the seatpost steps in. Its design allows micro-flex to smooth out vibrations that, over time, wear down your muscles and strain your lower back.
Phase two: impacts
On rougher sections—roots, drops, steps, or rocks—the Softex™ system works as one. The rear triangle flexes progressively, absorbing stronger impacts without compromising the bike’s stiffness or responsiveness.
+ Performance
Unbreakable spirits
You fight the mud, the wind, and every rival on the trail. But your biggest battle is within.
Beating the pain. Silencing doubt. Because the real victory isn’t beating others—it’s defeating your own mind when everything hurts.
950 G FRAME AND 420 G FORK
LIGHTNESS TO GO FURTHER
Every gram saved is one more kilometer with less effort. In ultra-distance gravel races, where fatigue and elevation add up endlessly, bike weight becomes a tactical advantage.
Naii features a frame of just 950 grams—302 g lighter than its predecessor, the Allroad. Combined with a new 420 g carbon fork (110 g lighter), the total weight drop is instantly noticeable on the first climb.

But it’s not just about weight. This was achieved through a new high-modulus carbon layup, with fibers placed strategically to ensure stiffness in power zones (bottom bracket and chainstays) while allowing flex and absorption in impact zones (seatpost, seatstays, top tube).
This balance of weight, stiffness, and comfort makes Naii agile on climbs, fast on rolling sections, and confident on technical descents. Lightweight, yes—but built to endure your hardest efforts.
Because fast gravel means a bike that doesn’t slow you down.

EVERY PEDAL STROKE COUNTS AND FULL STIFFNESS AND POWER TRANSFER
Naii’s frame was designed with one clear goal: to send every bit of energy from your legs to the ground—without losses. And it achieves it through a high-modulus carbon structure, with fibers oriented to maximize lateral and torsional stiffness.
This gives you a bike that reacts instantly. Whether you’re attacking on a false flat, sprinting to catch a group, or grinding up a technical climb:
Naii turns your power into speed.
This stiffness isn’t just about saving seconds. It helps you maintain cadence with less effort, without energy loss in each stroke, critical in long events. And with geometry optimized to keep you in an efficient position, you can hold your pace for hours without straining your back or arms
Unlimited Speed
The new NAII is your ideal partner: cutting-edge technology and top components to conquer any challenge. Experience gravel adventure like never before.
Up to 50 mm Tire Clearance
The fork supports tires up to 50 mm wide, offering more versatility and allowing you to tune the bike to your terrain or riding style.
Avan Handlebar
Our exclusive 320 g handlebar offers impressive stability, grip, and control—helping you ride with confidence when braking and cornering.
Comfort with Softex Technology
This system enables progressive flex of 2.8 cm in the seatstays, boosting comfort, stability, and traction on rough terrain, while ensuring efficient power transfer.
Top Tube
The top tube allows you to mount a small tool bag securely and aerodynamically—keeping essentials within reach without compromising performance.
Customize your NAII with Berria Iris
Every rider is unique. That’s why every Naii can be unique too. Thanks to the Berria IRIS customization program, you can tailor your bike—not just with colors and finishes, but with key components: wheels, gearing, cockpit, transmission, tires, and more.
This is not just about looks—it’s a performance tool. A rider doing ultra-gravel needs a different setup than someone racing 100 km. A heavier or more powerful cyclist may need different wheels than a lighter one. Every detail counts—and with Naii, you can choose them all. Because a bike that will be with you for hundreds of hours of riding and racing should reflect who you are.
And most importantly. It should respond just the way you expect.
Ready to win
To reach your goals, every detail matters. That’s why Berria partners with the best components—to match the elite performance of the new Naii.
