Berria gravel bike: Naii X Pro – SRAM RIVAL XPLR AXS PWM – Vision TC45 – Airone GR – Dark Grey 2027

Berria Naii X Pro 2027: a high-performance, versatile carbon gravel bike

The Berria Naii X Pro Rival XPLR AXS PWM 2027 is a carbon gravel bike designed for cyclists looking for a fast, precise and versatile bike for a variety of terrains and distances. Its frame NAII X in HM2X carbon, its electronic transmission SRAM Rival XPLR AXS 13-speed, its carbon wheels Vision TC45 and its integrated cockpit Avanforce Airone GR form a performance-oriented ensemble.

This version Dark Grey combines a understated, sporty finish with the modern lines of the NAII X. With its ability to accommodate tyres up to 700 x 50C, the Berria Naii X Pro It can handle both smooth tracks and rougher terrain, whilst maintaining dynamic handling on fast sections.

An HM2X carbon frame designed for competitive gravel riding

The Berria Naii X Pro is based on a framework NAII X Full Carbon HM2X, manufactured using a construction method Triple Monocoque. This design combines different levels of stiffness to create a frame that is both responsive to pedalling and suited to the specific demands of gravel riding.

The manager benefits from the technology Active Stay, a design that encourages vertical flex in the stays to improve the bike’s ability to absorb uneven ground.

The NAII X also features a storage space built into the down tube, a bottom bracket T47 and internal cable routing via the system ICS2.

The NAII X-specific carbon fork completes this design and allows for tyres up to 700 x 50C.

Active Stay and SOFTEX: two distinct technologies

The comfort of the Naii X Pro is based on several elements which should be distinguished from one another.

Technology Active Stay is part of the frame’s design. It acts on the seat stays to promote a degree of vertical flexibility whilst maintaining the dynamic qualities required for cycling.

Technology SOFTEX, for its part, is integrated into the Avanforce Tibia SOFTEX UD Carbon seatpost. This 27.2 mm seatpost is designed to provide greater cushioning at the point of contact between the bike and the rider.

The Naii X Pro therefore does not have a frame with ‘SOFTEX travel’: SOFTEX here refers to the seatpost technology.

Transmission SRAM Rival XPLR AXS 13-speed

The Berria Naii X Pro is hosting the electronic band SRAM Rival XPLR AXS E1 in configuration 13 gears.

The crankset SRAM Rival XPLR AXS E1 PWM is fitted with a tray 42 teeth and works with a cassette SRAM XPLR XG-1351 10–46 teeth.

This single-chainring drivetrain offers a range of gear ratios suited to the various conditions encountered on gravel rides. The 10-tooth chainring allows you to maintain a high gear ratio on fast-paced sections, whilst the 46-tooth sprocket provides sufficient power reserve for climbs and more undulating terrain.

Electronic technology AXS enables precise gear changes whilst contributing to the bike’s exceptionally sleek design.

Carbon wheels Vision TC45

The Naii X Pro The Rival XPLR AXS PWM 2027 is fitted with carbon wheels Vision TC45.

With their profile of 45 mm, their internal width of 23 mm and their design Tubeless Ready, these wheels reflect the bike’s sporty character.

Their profile helps improve performance on fast sections whilst providing a suitable base for gravel tyres of various widths. Tubeless fitting also allows you to adjust the tyre pressure and the bike’s handling to suit the characteristics of the route.

Avanforce Airone GR integrated carbon cockpit

The pilot’s seat is entrusted to theAvanforce Airone GR Integrated Gravel Carbon.

This integrated carbon cockpit features the cable routing system ICS2 Full Internal, giving the bike a particularly clean finish. The cables are routed inside the cockpit and the headset to the frame.

The cockpit also features mounting options for GPS and GoPro, which makes it easier to fit accessories for training rides, long-distance rides or gravel rides.

A pneumatic capacity of up to 700 x 50C

The frame and fork of the Berria Naii X Pro accept tyres up to 700 x 50C.

This feature allows you to adapt the bike’s handling to suit the terrain. Narrower tyres may prioritise efficiency on fast sections, whilst a wider tyre profile can offer greater comfort, traction and control when the trails become more technical.

This versatility makes the Naii X Pro a gravel bike suitable for a wide variety of routes.

Advanced integration

The Berria Naii X Pro The 2027 features a modern design with integrated wiring, a one-piece carbon fibre cockpit, and integrated and standard storage UDH for the rear derailleur.

The frame uses a through-axle of 12 x 142 mm at the rear, whilst the fork is fitted with a 12 x 100 mm at the front.

The system is complemented by a hydraulic braking system SRAM Rival AXS E1 and a bottom bracket SRAM DUB Wide T47.

A understated and sporty Dark Grey colourway

The finish Dark Grey gives the Berria Naii X Pro a subtle, modern design. Combined with the lines of the carbon frame, the integrated cockpit and the wheels Vision TC45 – it emphasises the sporty nature of this gravel bike.

This colourway is particularly aimed at cyclists looking for a high-performance bike with a understated design, without an excess of visual contrasts.
