Berria Mistral Carbon electric road bike Pro, Ultegra Di2 – Vision TC45 – Airone Chalk Grey 2027

The 2027 Mistral Carbon BR Ultegra Di2 eBerria is a top-of-the-range electric road bike designed for cyclists looking for a sporty ride, controlled comfort and unobtrusive electric assistance. With its HM2X carbon frame, 12-speed UlShimano Di2 groupset, Vision TC45 carbon wheels and Bosch Performance Line SX motor, the Mistral combines efficiency and assistance in a truly premium design.

A carbon e-road bike designed for performance

The frame of the Berria Mistral Carbon is based on a Full Carbon HM2X construction combined with MACH-R Nanotech and Triple Monocoque technologies. This design aims to achieve an excellent balance between stiffness, strength and comfort, whilst managing the specific challenges associated with integrating an electric system.

The frame also features the Active Stay system, with geometry incorporating 28 mm of travel thanks to the SOFTEX suspension system. This design provides greater flexibility and vibration damping without turning the Mistral into a dedicated off-road bike.

With its fully integrated ICS2 cable management system, the cockpit retains a particularly clean, uncluttered look. The integrated Avanforce Airone carbon handlebars also contribute to this meticulous integration.

Bosch Performance Line SX assistance

The 2027 Berria Mistral Carbon BR Ultegra Di2 is fitted with the Bosch Performance Line SX Smart System, a motor particularly well-suited to sporty e-cycling. It delivers up to 55 Nm of torque and has a claimed maximum power output of 600 W.

The system is powered by a 400 Wh Bosch CompactTube battery, integrated into the frame. The Bosch system is complemented by the colour LED System Controller and the eBike Flow app, allowing you to manage and customise the assistance experience.

This drivetrain allows you to maintain a riding style similar to that of a traditional road bike, whilst providing valuable assistance on climbs, on long rides or when fatigue starts to set in.

Shimano Ultegra Di2 12-speed

The Ultegra Di2Shimano s groupset is one of the key strengths of this configuration. The 12-speed electronic drivetrain offers fast and precise gear changes, perfectly suited to sporty riding.

The bike is fitted with an 11–34-tooth cassette, offering a versatile gear range for switching between fast sections, long climbs and undulating terrain. Braking is provided by Shimano Ultegra hydraulic disc brakes, ensuring effective control whatever the riding conditions.

Vision TC45 carbon wheels

The build is completed by Vision TC45 carbon wheels, Tubeless Ready, featuring a 45 mm-high rim and an internal width of 23 mm.

This rim height offers an attractive balance between aerodynamics, efficiency and versatility. They enhance the Mistral’s sporty character whilst remaining suitable for use on a variety of route profiles.

A design focused on comfort

The Mistral Berria isn’t just about performance. Its design combines several technologies aimed at improving comfort over long distances.

The all-carbon Mistral EVO fork features offset adjustment via a flip-chip system, whilst the frame accommodates tyres up to 700 x 50c. This flexibility offers a useful range for adapting the bike’s handling to the type of route and the desired level of comfort.

The Belador 6 SP carbon seatpost and the Fizik Vento Argo X5 saddle round off this sporty endurance-oriented setup.

A premium eRoad bike with a sporty character

With its Chalk Grey colour scheme, its particularly neat integration and its top-of-the-range components, the Berria Mistral Carbon BR Ultegra Di2 2027 is aimed at cyclists who wish to retain the feel and aesthetics of a modern road bike whilst benefiting from electric assistance.

It is a particularly good choice for hilly rides, long distances and routes where the aim is to get more out of cycling without compromising on a dynamic and sporty ride.
