Berria NAII BR Rival XPLR AXS PWM Gravel Bike – Vision Team 30 Naked Carbon Kerochalk 2027

The Berria NAII BR Rival XPLR AXS PWM Naked Carbon Kerochalk is a top-of-the-range carbon gravel bike designed for cyclists looking for performance, comfort and versatility. This configuration combines the carbon frame Berria NAII BR with integrated suspension technology SOFTEX, an electronic transmission SRAM Rival XPLR AXS with PWM power metre, wheels Vision Team 30 and a coat hanger Alloy Avanforce.

Its colour Naked Carbon Kerochalk really brings out the best in the frame’s carbon construction and gives the bike a understated, technical and premium look.

Designed around a philosophy Fast Gravel, the NAII BR is just as at home on fast tracks as it is on rougher terrain. It is designed to maintain excellent performance whilst enhancing comfort over long distances.

Berria NAII BR: a carbon frame designed for fast gravel riding

The setting Berria NAII BR forms the heart of this high-performance gravel bike. Its carbon design is engineered to offer a balance between stiffness, dynamism and shock absorption.

Berria has developed the NAII around a design intended for fast gravel riding. The bike thus maintains precise steering and dynamic handling whilst offering sufficient stability as speed increases on the tracks.

The colour Naked Carbon Kerochalk gives it a particularly elegant visual identity. The exposed carbon finish emphasises the frame’s high-end character and gives the bike a decidedly sporty look.

SOFTEX technology: 28 mm of travel for greater comfort

Technology SOFTEX is one of the main features of the Berria NAII BR.

The system allows for approximately 28 mm of travel at the rear, in order to improve the absorption of bumps encountered on the tracks.

The aim is not to replicate the handling of a full-suspension mountain bike, but to retain a fast gravel bike whilst reducing the vibrations and impacts transmitted to the rider.

This technology is particularly useful when:

• long gravel rides ;
• routes on rough tracks ;
• fast descents on tracks ;
• long-distance events ;
• outings where comfort becomes a factor in performance.

The SOFTEX system therefore helps to maintain good contact with the ground and provides greater control when the surface becomes uneven.

Transmission SRAM Rival XPLR AXS

The Berria NAII BR Rival XPLR AXS PWM is fitted with an electronic transmission SRAM Rival XPLR AXS, specially developed for gravel riding.

AXS technology eliminates the need for traditional control cables, replacing them with an electronic system. Gear changes are fast, precise and easy to customise.

The XPLR transmission features a configuration single chainring, which is particularly well-suited to gravel riding as it simplifies the drivetrain’s operation and minimises the need for adjustments on technical terrain.

A built-in power sensor for training

The designation PWM indicates the presence of a power sensor on the crankset.

This kit transforms the NAII BR into a genuine training tool. Power measurement allows you to monitor the intensity of your effort precisely and manage long rides more effectively.

The power sensor is particularly useful for:

• working with power zones ;
• track its progress ;
• tailor your training sessions ;
• managing one’s effort during a competition ;
• compare different outputs ;
• optimise your preparation for gravel races.

For a regular cyclist or competitive cyclist, this is a particularly useful piece of kit.

Wheels Vision Team 30

This configuration Naked Carbon Kerochalk receives wheels Vision Team 30.

Their 30 mm profile offers an attractive balance between performance, versatility and durability.

Unlike a bike fitted with high-profile carbon wheels, the Vision Team 30 bikes favour a more versatile approach. They are perfectly suited to a mix of road and gravel riding and also allow for the bike to be upgraded at a later date.

They are therefore a sensible choice for a cyclist wishing to prioritise investment in the carbon frame, electronic drivetrain and SOFTEX system.

Avanforce alloy handlebar

The NAII BR Naked Carbon Kerochalk is fitted with a Avanforce alloy handlebar.

This choice offers a significant practical advantage: unlike an integrated carbon cockpit, a traditional handlebar makes it easier to adjust the riding position.

This makes it easier to adjust the width or position, or to replace the hanger if necessary.

For a bike designed for long distances, this ability to fine-tune the position can be a real advantage.

The Naked Carbon Kerochalk colourway

The Naked Carbon Kerochalk contributes to the Berria NAII BR: a particularly distinctive aesthetic.

The exposed carbon finish emphasises the frame’s lines and enhances its premium feel. The contrast with the components Kerochalk gives the bike a look that is both understated and sporty.

This colourway will be particularly suited to cyclists looking for a top-of-the-range bike with a finish that differs from traditional fully-painted frames.

A gravel bike designed for competitive cyclists

The Berria The NAII BR is not just for leisure use. It is clearly designed for cyclists who are looking for performance and want to maintain a high speed on the tracks.

It is particularly suitable for:

• gravel races ;
• long distances ;
• sports outings ;
• fast gravel ;
• routes that combine roads and footpaths ;
• training with a power meter ;
• cyclists looking for a versatile carbon gravel bike.
