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

Unique in its class with its special custom configuration, this Berria Naii BR Iris Custom Almagra is built around a lightweight and comfortable carbon frame, thanks to a combination of T700, T800 and T1100 carbon fibres. It offers a perfectly balanced blend of lateral stiffness and vertical compliance, allowing you to switch effortlessly between roads and trails.

Comfort and traction are also optimised thanks to SofTex technology, which provides greater flex in the seat stays. The new Avanforce Tibia carbon seatpost, with its openwork design, ensures excellent vibration absorption without compromising pedalling efficiency.

This Naii BR Iris Custom Almagra is fitted with high-quality components, including a Sram Rival XPLR AXS 13-speed groupset, which ensures precise gear changes and high-performance disc braking in all conditions. The crankset is fitted with a power meter to help you track your progress. Finally, the Vision SC45 carbon wheels ensure excellent performance on all terrains.
