G8 Disc

This is the bike for you if

The new G8 road bike, with disc brakes, is the perfect choice for cyclists who are looking for a lightweight and aerodynamic bike with internal cabling and outstanding performance.

Its unique technology is

The G8 Disc road bike was designed based on the parameters defined by aerodynamic tests in the wind tunnel and fluid dynamics technology. Its monocoque carbon frame combines Toray T800 and T800 carbon fibres and Pitch Fiber carbon fibres in critical areas. The frame weighs just 850 grams.

It’s different because

The G8 Disc bike features ACR steering, enabling 100% internal cabling.

ACR STEERING

The G8 Disc bike features ACR steering, enabling 100% internal cabling and ensuring very clean lines.

BH

TYRE WIDTH CLEARANCE 28 MM

It offers 28 mm tyre width clearance; the optimal size for greater rigidity and safety, optimising the position of the brake.

BH

SLOPING GEOMETRY

The raised steering tube and a short rear triangle provide a lower centre of gravity and allow for optimal manoeuvrability. The narrower, shorter and asymmetric chainstays and the design of the back brake achieve a much more responsive and rigid rear that improves pedalling performance on ascents.

BH

DOUBLE CLAMP

This system, with a double clamp on the seat stay, provides aerodynamics and additional safety.

BH

HIDDEN LEVERS

New 12 mm thru-axle fasteners provide a compact and more aerodynamic design. Wing nut threading ensures ease of installation.

BH

KAMM TAIL DESIGN

To achieve the aerodynamic and innovative cross section and optimal geometry of the rear triangle, computer analyses and fluid dynamics tests were carried out. The R&D team identified the cross-sectional areas that had the best results for enhancing them on the G7 Disc frame. Its Kamm Tail design in the shapes of the tubes optimises the passage of air.
