Its endurance design inspired by the G6 Pro. It incorporates semi-sloping aerodynamics that makes it the ideal bicycle for a wide range of cyclists.
Its reactive, aerodynamic frame, and great performance & stability, provides comfort to cyclists during the ride. Its vertical absorption is optimal, its BB386 EVO bottom bracket, the elevated steering post, the 27.2 mm seat post, its only 950 g* (in the M size) and the possibility of integrating the D12 battery into the seat post, make the Quartz a comfortable, efficient bicycle with a great amount of features. The Quartz Disc range incorporates Shimano Flat Mount brakes that are directly connected to the frame.
100% CARBON. STANDARD FLAT MOUNT SYSTEM
With the design and development of the Quartz line, BH has created a lightweight yet responsive top-performing frame which stands second none in its category.
The Quartz frame is a full carbon monocoque design developed using a highly specific carbon layup and molding technique. This innovative technology allows for greater control and optimization of the material thicknesses throughout the frame design. A specific blend of high modulus carbon fiber was selected specifically to meet the performance targets set by the BH development team, which resulted in a spectacular aerodynamic design that is lightweight and offers optimal vertical compliancy.
The Quartz Disk frames incorporate the new Shimano Flat Mount standard. The new Shimano Flat Mount standard offers lightweight, aerodynamics and built-in integration in the frame without the need of adaptors. Summarising, a more agile bicycle for the cyclist.
AERODYNAMIC FORK AND ASYMMETRIC REAR PODS
The Quartz fork, like that of the G6, is manufactured using a unique carbon design which fits the headset like a glove. The result is a smooth transition between frame and fork in both looks and performance.
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 wider wheel designs.
LATERAL AND VERTICAL RIGIDITY
The BB386 EVO bottom bracket, an innovation co-developed by BH in collaboration with FSA, incorporates an overall bottom bracket width of 86.5 mm. This optimized bottom bracket design allows the frame builder to increases overall frame stiffness while increasing rear tire clearance required of wider wheel designs. Using this system, BH has increase the torsion stiffness in the bottom bracket of the Quartz resulting in increased rider efficiency. The result is improved lateral stiffness, greater stability and increased control with each turn
of the pedals.
SEMI-SLOPING GEOMETRY. REAR TRIANGLE OF ONLY 406 MM
The design of the frame is slightly sloped to guarantee safety and rider ergonomics. Its semi-sloping geometrics places the gravity centre lower and its rear triangle, of only 460 mm, guarantees reaction capacity and more stability for the rider.
27.2 MM SEAT POST
The Quartz seat post is only 27.2 mm in diameter, similar to that used on the Ultralight model. This design offers additional weight savings to the overall frame while adding greater vertical compliancy.
