Berria road bike Belador Pro Shimano Ultegra Di2 12-speed Mavic Comete 50 Black Liquid Metal 2027 carbon

The Berria Belador Pro Shimano Ultegra Di2 12-speed 2027 Black Liquid Metal is a high-performance carbon road bike designed for cyclists seeking maximum efficiency, precision and speed. With its frame Full Carbon HM2X, its racing geometry, its aerodynamic integration and its electronic drivetrain Shimano Ultegra Di2 12-speed, the Belador Pro is positioned as a genuine racing machine.

This layout takes on even more character with the carbon wheels Mavic Comete 50, a pair of top-of-the-range 50 mm aero wheels designed to combine speed, responsiveness and control. Weighing just 1,315 g per pair, with an internal width of 23 mm, carbon spokes and bearings Mavic Made from ceramic, the Comete 50 brakes deliver a level of performance that is particularly well suited to the Belador’s sporty character Pro. .

The result is a road bike that offers a particularly consistent ride: Aerodynamic on the flat, responsive when accelerating, precise at high speeds and versatile enough for hilly and mountainous routes.

A carbon road bike designed for competition

The Berria Belador Pro is based on a framework Belador 6 Full Carbon HM2X featuring a triple monocoque construction. Its design combines rigidity, lightness and aerodynamic efficiency to enhance power transfer and performance.

The Belador’s Racing Geometry Pro is designed for cyclists looking for a dynamic and precise ride. The technology Aero Shape Efficiency (ASE) works on the frame’s shape to improve aerodynamic efficiency without turning the bike into a machine designed exclusively for time trials.

Berria also offers full integration of cabling via the system ICS2, for a particularly sleek finish and a more seamless integration of the cockpit.

The T47 bottom bracket completes this modern design and helps to provide a rigid and durable platform.

Shimano Ultegra Di2 12-speed: electronic precision

The Shimano Ultegra Di2 12-speed is one of the key elements of this configuration.

The electronic drivetrain delivers fast, precise and smooth gear changes, which are particularly beneficial during acceleration, changes in pace or when the cyclist needs to change gears whilst pedalling hard.

The assembly includes, amongst other things, a pedal set Shimano Ultegra FC-R8100, 52/36 teeth combined with a cassette 11–34 teeth.

This combination is particularly well-suited to a versatile competition bike. The 52-tooth chainring maintains excellent efficiency as speed increases, whilst the 34-tooth chainring provides a welcome reserve of power on climbs.

The benefits of the Shimano Ultegra Di2 12-speed

• Fast and precise electronic gear changes.
• 12 gears for optimum gear ratio.
• 52/36 chainring set suitable for competitive cycling.
• Versatile 11-34 cassette.
• Hydraulic disc brakes.
• Ergonomics and precision Shimano Ultegra.

Mavic Comete 50: the choice of high-performance carbon wheels

One of the main advantages of this configuration is the installation of the Mavic Comete 50 Carbon.

With their profile of 50 mm, the Comete 50 wheels are designed as versatile aero wheels. They are intended to enable cyclists to maintain high speeds whilst retaining good responsiveness during accelerations and climbs.

The rim has an internal width of 23 mm and a maximum external width of 30 mm. Mavic In particular, it recommends the use of 28 mm tyres to maximise the wheel’s aerodynamic potential.

The stated weight of 1,315 g per pair is particularly interesting for a 50 mm carbon wheel. It results in a wheel that is both aerodynamic and light enough to maintain performance when the road climbs.

A high-end carbon construction

The Mavic Comete 50 models feature a construction Adaptive Layup combining several types of carbon fibre, notably T700, T1000 and 3K. This design aims to strike a balance between stiffness, weight and dynamic behaviour.

The pair uses 21 carbon spokes per wheel, with a design intended to strike a balance between power delivery, rigidity and stability.

Mavic also fits the Comete 50 from Ceramic bearings and the freewheel system ID360 with 40 teeth, designed to provide a quick response when you start pedalling again.

A 50 mm profile for greater speed

The 50 mm profile strikes an excellent balance for a modern road bike.

On rolling sections, slight inclines and fast descents, the rim height helps to improve aerodynamic efficiency. However, unlike an extremely tall wheel, a 50 mm profile retains a degree of versatility for hilly routes.

Mavic states that it developed the Comete 50’s Aero Wide profile using wind tunnel testing in Geneva. The brand also claims a time saving of up to 12 seconds over 50 km compared with the Cosmic SLR 45 under its test conditions.

Important: this figure is a manufacturer’s specification obtained under a specific test protocol and should not be interpreted as a guaranteed benefit for every cyclist or every route.

A fully integrated carbon cockpit

The Belador Pro features a cockpit Avanforce Airone Integrated Carbon with cable routing via the ICS2 system.

This solution enhances the bike’s overall appearance and contributes to its aerodynamic profile. It also creates a particularly clean handlebar area, with no visible cables.

A GPS mount is also fitted to the cockpit.

Braking Shimano Hydraulic Ultegra

Braking is handled by Shimano Ultegra hydraulic disc brakes, a solution perfectly suited to Belador’s sporting philosophy Pro.

Disc brakes offer powerful and controllable braking, with particularly good control on fast descents or when weather conditions deteriorate.

The assembly is fitted with discs Shimano RT-MT800 Centre Lock, 160 mm at both the front and rear, depending on the specified configuration.

A fast yet versatile bike

The Berria Belador Pro could easily be regarded as a bike designed exclusively for competition. Yet its association with the Mavic The Comete 50, combined with the Ultegra Di2 12-speed drivetrain, makes it a highly versatile bike.

It really comes into its own on:

• quick routes ;
• cyclosportives ;
• long sporting outings ;
• hilly routes ;
• high-intensity training sessions ;
• road races ;
• fast-paced group outings.

The pneumatic clearance also allows for the use of modern tyre sizes, with compatibility claimed to be up to 700 x 32 mm for the frame and 700 x 34 mm for the fork in the Belador configuration Pro.

For a high-performance cyclosportif rider, an amateur competitor or a cyclist who wants a single bike capable of handling almost anything quickly, this combination is particularly well-suited.

Our only advice: don’t choose this bike based solely on its features. The frame size, position and choice of tyres will have a significant impact on the overall riding experience. A racing bike that is correctly set up will always be more effective than a setup that is theoretically higher-spec but poorly suited to the rider.
