| Features | 100% Carbon: With the design and build of the Quartz line, BH has created a more responsive, lightweight and top-performing frame without renouncing stability and safe performance. The Quartz is a monocoque frame made of 100% carbon fibre using core removal technology, as in the G6 and Ultralight models. This innovative technology allows for control and optimization of the ideal thickness's for the various frame parts, selecting the most appropriate carbon fibres and keeping their superimposition to a minimum. This results in a spectacular aerodynamic design, extreme rigidity and lightness and optimal vertical absorption performance. The result is a model that offers excellent handling and performance through efficient pedalling, turning all of your effort into power, thanks to its lateral stiffness. Weighing in at only 950 grams in the M-size, the Quartz frame is one of the lightest and most efficient in its category.
The most aerodynamic fork: The Quartz fork, like that of the G6, is manufactured in one carbon piece and fits the headset like a glove, resulting in a smooth transition between these two elements.
Asymmetrical rear chainstays: The rear chainstay design is asymmetrical, as in the other BH top of the line frames, in order to increase the lateral stiffness of the frame and to allow installation of larger wheels, as well as to improve the wheel's rotation.
Integrated 1.5” carbon headset: The conical carbon 1.5” headset, inspired by the G 6 line, is fully integrated within the frame. This allows for exceptional torsion stiffness and handling ratios, prioritising stiffness at this point. The diagonal section of the headset has been reduced by over 11% for increased efficiency, lower air resistance and improved aerodynamics.
27.2mm seatpost for comfort:
The Quartz frame's seat post is only 27.2 mm in diameter, as in the Ultralight model. Its design offers lightness to the frame as well as added comfort while riding.
BB386EVO:
The BB386 EVO bottom bracket, an innovation developed by BH in collaboration with FSA, allows for an oversizing of the external width of the bottom bracket up to 86.5 mm. at the base and thus, an increase in surface area, stiffness and resistance. Through this system, BH has managed to increase the lower tube diagonal up to 80% in diameter, decreasing wall thickness and increasing the torsion stiffness in the crankset and rear frame area. The result is total lateral stiffness and complete stability, increased control and overall efficiency with each turn of the pedals.
Internal cable routing:
Cables are routed inside the frame for a clean look and to protect them from the elements.
