Berria Naii BR GRX 800 Vision Trimax 30 Iris Desert Storm 2026 gravel bike

The Berria Naii BR GRX800 12v features a lightweight and comfortable carbon frame in Desert Storm colours. It offers a perfectly balanced combination of lateral stiffness and vertical flexibility, allowing you to switch seamlessly between roads and trails thanks to the combination of T700, T800 and T1100 carbon fibre. Comfort and traction are also optimised thanks to SofTex technology, which provides greater flex in the seat stays.

The new Avanforce Tibia carbon seatpost features an openwork design that ensures excellent vibration absorption without compromising pedalling efficiency. You’re looking at a gravel bike that strikes the perfect balance between efficiency and comfort, delivering an excellent ride feel on all types of surfaces.

The Naii BR, with its seamless integration, is perfectly configured to offer excellent value for money. It features the Shimano GRX800 2x12-speed groupset, Vision Trimax 30 aluminium wheels and a carbon handlebar-stem combo. A package that delivers a high-quality bike at an exceptional price, just as Berria is known for, for your greatest enjoyment.
