Berria NAII BR Rival XPLR AXS PWM: the high-performance carbon gravel bike

The Berria NAII BR RIVAL XPLR AXS PWM 2027 is a high-end carbon gravel bike designed for cyclists seeking speed, precision and comfort over long distances. With its frame HM3X carbon NAII, its integrated suspension 28 mm SOFTEX, its electronic transmission SRAM Rival XPLR AXS E1 13-speed and its carbon wheels Vision TC45, this gravel Berria is clearly positioned in the performance segment.

The NAII BR combines an aerodynamic design and fast gravel-oriented geometry with tyre clearance of up to 700 x 50C. It also features an integrated carbon fibre cockpit Avanforce Airone GR, a carbon seatpost fitted with the SOFTEX system and fully integrated cable routing via the ICS2.

In summary: the Berria The NAII BR Rival XPLR AXS PWM is a competition-grade gravel bike designed to combine performance, comfort and control across a wide variety of terrain.

An HM3X carbon frame designed for performance

The heart of the Berria NAII BR is its framework 100% HM3X carbon, produced using a construction method Triple Monocoque. This architecture enables Berria to fine-tune the frame’s stiffness and handling whilst maintaining a performance-oriented approach.

The frame features BGC geometry and incorporates the suspension system SOFTEX, offering 28 mm of travel at the rear. This technology is one of the NAII’s key features: rather than relying solely on the flexibility of the tyres, Berria directly incorporates additional shock-absorbing capability into the bike’s design.

The frame also features a bottom bracket shell T47, with 12 x 142 mm through-axles, and a standard derailleur hanger UDH and compatibility with tyres up to 700 x 50C.

The SOFTEX system: comfort that enhances speed

One of the most interesting aspects of the Berria NAII BR is his system SOFTEX.

With 28 mm of travel, this integrated suspension is designed to improve the absorption of vibrations and bumps without turning the NAII into a heavy or clunky off-road bike.

When it comes to fast gravel riding, the benefits are clear: on a rough track, better shock absorption helps you retain more control and stay on course more easily.

The SOFTEX system is combined with a Avanforce NAII Tibia carbon seatpost, with zero offset, specifically developed for the NAII.

Transmission SRAM Rival XPLR AXS E1 13-speed

The transmission is another highlight of this set-up.

The Berria NAII BR Rival XPLR AXS PWM welcomes the group SRAM Rival XPLR AXS E1, with wireless electronic transmission and 13 gears.

The package includes, in particular:

• Orders SRAM Rival XPLR AXS E1.
• Rear derailleur SRAM Rival XPLR AXS E1 13-speed.
• Crankset SRAM Rival E1 PWM in 42 teeth.
• Cassette SRAM XPLR XG-1351 in 10–46 teeth.
• Hydraulic disc brakes SRAM Rival AXS E1.
• Bottom bracket shell SRAM DUB Wide T47.

Choosing a single chainring 42 teeth When paired with a 10-46T cassette, it is particularly well-suited to competitive gravel riding. It offers an easy-to-use gearing system and a sufficiently wide range to switch quickly between fast-paced sections and more demanding climbs.

The minimal development of 42 x 46 In particular, it allows you to maintain a relatively low gear ratio on climbs, whilst the 10-tooth sprocket is ideal for accelerating and on fast sections.

Carbon wheels Vision TC45

The original fitment is complemented by a pair of Vision TC45 carbon.

These wheels feature a tubeless-ready carbon rim measuring 45 mm high, with an internal width of 23 mm and a Centre Lock mounting system.

This choice is particularly consistent with the bicycle’s positioning. The Vision The TC45 tyres offer a relatively high profile whilst remaining versatile enough for fast gravel riding.

Combined with the carbon frame and integrated cockpit, these features help give the NAII BR a more speed-oriented ride than more traditional gravel bikes fitted with low-profile aluminium wheels.

Avanforce Airone GR integrated carbon handlebar

The cockpit is also particularly high-end.

The Berria The NAII BR Rival XPLR AXS PWM receives the Avanforce Airone GR integrated carbon handlebar, with all cables routed through the ICS2 system.

Berria offers a range of sizes, including:

• 405 x 80 mm ;
• 425 x 90 mm ;
• 425 x 100 mm ;
• 425 x 110 mm ;
• 445 x 120 mm.

The hanger also has hooks Built-in GPS and GoPro.

This integration contributes to the bike’s very high-end finish, whilst enhancing its appearance and minimising the number of visible cables.

A carbon fork capable of accommodating 700 x 50C tyres

The fork Berria The NAII BR is made entirely of carbon fibre and also features internal cable routing.

It accepts discs up to 160 mm and tyres up to 700 x 50C. Its rake is 48 mm, with an axle-to-crown length of 395 mm.

This tyre capacity is important for a bike that aims to be both high-performance and versatile. Depending on the terrain and the type of tyre used, the cyclist can therefore prioritise performance with a narrower cross-section or increase the volume to gain comfort, grip and control.

Geometry of the Berria NAII BR

Berria proposes the NAII BR of the XXS to XL, with indicative recommendations ranging from less than 1.50 m to more than 1.90 m.

In size M, the frame has a reach of 405 mm, a stack of 556.5 mm and a wheelbase of 1,026.4 mm. The head angle is 71.5° and the chainstays measure 420 mm.

This geometry underlines the bike’s sporty character: the NAII BR is designed to maintain precise steering and dynamic handling whilst offering sufficient stability for fast gravel rides.
