The result is a gravel bike that is particularly appealing to cyclists who wish to to drive fast on the road whilst still having the freedom to head off onto the tracks.

An HM3X carbon gravel frame with SOFTEX suspension

The NAII is the gravel performance platform of Berria. Its frame is constructed using Full Carbon HM3X Triple Monocoque, with a design intended to achieve an excellent balance between rigidity, weight and dynamic performance.

The HM3X material from Berria combines several high-modulus carbon fibres, including Toray T700, T800 and T1100G. This combination is designed to optimise the stiffness-to-weight ratio and maintain precise handling.

But the NAII’s most distinctive feature lies in its system SOFTEX.

SOFTEX: 28 mm of travel for greater comfort

The NAII frame incorporates a SOFTEX suspension system offering 28 mm of travel. This technology absorbs some of the vibrations and shocks caused by uneven paths without turning the bike into a proper mountain bike.

On long gravel rides, this ability to absorb bumps in the terrain can help reduce fatigue and improve control of the bike.

The concept is particularly useful for routes where you switch rapidly between tarmac, gravel and rougher terrain.

A proper Fast Gravel machine

Berria presents the NAII as a bicycle that Fast Gravel, with a philosophy clearly focused on speed and performance.

The BGC geometry is designed to deliver dynamic handling whilst maintaining sufficient stability when the terrain becomes technical. The frame accommodates tyres up to 700 x 50C, which leaves plenty of scope to adapt the bike to the terrain and the desired level of comfort.

With relatively narrow tyres, the NAII can handle much like a road bike on tarmac sections. With 45 or 50 mm tyres, it handles much more comfortably on rough tracks and loose surfaces.

Shimano GRX800 Di2 12-speed

The transmission Shimano GRX800 Di2 12V is perfectly in line with the NAII’s philosophy.

The electronic gravel groupset delivers precise and rapid gear changes, even when the terrain requires frequent changes in cadence.

The package includes, in particular:

• levers Shimano GRX Di2 ST-RX825
• rear derailleur Shimano GRX Di2 RD-RX825
• front derailleur Shimano GRX Di2 FD-RX825
• crankset Shimano GRX FC-RX820-12
• 48/31-tooth double chainring
• cassette Shimano 11–34
• hydraulic brakes Shimano GRX BR-RX820

The jumpsuit 48/31 – 11/34 is particularly appealing for a versatile gravel bike. It allows you to maintain good speed on the road whilst still having a gear ratio that’s short enough for climbs on dirt tracks.

Why choose the 48/31 double chainring ?

A double chainring is a major advantage for a gravel bike designed for riding on both roads and tracks.

The 48-tooth chainring helps maintain good performance as speed increases on tarmac or rolling tracks.

The small 31-tooth chainring, combined with the 34-tooth sprocket, offers a gear ratio better suited to climbs and challenging gravel sections.

This set-up makes the NAII particularly versatile for cyclists who don’t want to have to choose between sporty gravel riding and long mixed-terrain rides.

Vision Team 30: a versatile and robust gravel wheel

This version of the Berria NAII is equipped with Vision Team 30 Disc.

The Team 30 models use an aluminium rim measuring 30 mm high and an architectural style that 24 spokes at the front and 24 at the rear. . Vision features six sealed cartridge bearings and is compatible with freewheel bodies Shimano and SRAM. .

The stated weight of the pair is 1,900 g. .

Why do the Vision Are Team 30 tyres any good for gravel riding ?

For versatile gravel riding, durability and ease of use may be more important than the absolute pursuit of lightness.

The Team 30 range is therefore a logical choice for:

• everyday gravel riding ;
• the white paths ;
• long distances ;
• mixed road/gravel rides ;
• courses with frequent changes in surface ;
• cyclists looking for a reliable set of wheels.

The 30 mm profile also offers a degree of aerodynamic performance whilst maintaining a reasonable rim height.

Tyres up to 700 x 50C

One of the major advantages of the NAII is its ability to accommodate tyres up to 700 x 50C. .

This feature allows you to tailor the bike’s performance to your riding style.

With tyres measuring 40 to 45 mm, the bike can prioritise efficiency and speed on fast-rolling tracks.

With a width of around 50 mm, it is more geared towards comfort, grip and off-road capability on tougher terrain.

The choice of tyre is therefore a key factor in realising the full potential of the NAII.

Avanforce Airone GR integrated carbon cockpit

The NAII receives a Avanforce Airone GR Integrated Gravel Carbon Handlebar, with fully integrated cable routing via the ICS2 system.

The hanger is available in a range of sizes and features brackets GPS and GoPro. .

This integration gives the product a particularly modern finish and helps to maintain a very clean-cut frame design.

Carbon seatpost with SOFTEX system

Berria combines the SOFTEX system with a seat post Avanforce NAII UD Carbon Shin Guard, with zero offset and available in lengths of 300 and 350 mm.

This design contributes to the bike’s overall comfort and is in line with the NAII’s philosophy: to maintain good efficiency whilst filtering out vibrations caused by uneven surfaces.

Braking Shimano GRX hydraulic

Braking is handled by the Shimano GRX BR-RX820 with hydraulic disc brake.

This system offers power and control tailored to the demands of gravel riding, particularly when the terrain becomes wet, steep or uneven.

Hydraulic braking also helps maintain precise control with wide tyres and on long descents.

A gravel bike for the road, the trails and adventure

The NAII BR GRX800 Di2 is not a gravel bike designed exclusively for easy trails.

Thanks to its generous ground clearance and SOFTEX system, it is capable of tackling more challenging terrain whilst remaining fast on fast-paced sections.

It is particularly suitable for:

• competitive gravel rides
• long distances
• gravel touring
• routes combining roads and footpaths
