Berria Naii BR Rival XPLR AXS 13-speed Vision SC45 Iris Desert Storm gravel bike with power meter 2026

Looking great in its Desert Storm colourway, this Berria Naii BR is the ideal bike for tackling gravel trails. It features a lightweight and comfortable carbon frame, thanks to a combination of T700, T800 and T1100 carbon fibres, offering a balance between lateral stiffness and vertical compliance. Comfort and traction are also optimised thanks to SofTex technology, which provides greater flex in the seat stays. The Avanforce Tibia seatpost, with its openwork design, ensures excellent vibration absorption without compromising pedalling efficiency.

This model, with its neat integration, is perfectly configured to offer you excellent value for money. Indeed, it features the new Sram Rival XPLR AXS 13-speed electronic groupset, which ensures precise and rapid gear changes, as well as high-performance disc braking in all conditions. The crankset includes an integrated power meter to help you manage your training sessions effectively and continue to progress. With Vision SC45 carbon wheels and a carbon handlebar-stem combo, the package delivers an ultra-competitive gravel bike at a fair price.
