Different thicknesses, different parts of the frame 0,9 mm
6. 27.2 mm seat post Added comfort while riding 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.

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 result is a model that offers excellent handling and performance through efficient pedalling using an optimized frame design.
3. The most aerodynamic fork 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.
4. Asymmetrical rear chainstays 4
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.
7. BB386 EVO Bottom bracket system. Increased lateral stiffness 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.
8. Cable guides within the frame. Maximum protection, easy maintenance The cable guide system used by the Quartz is the same as in the G6 and Ultralight models. It allows for the integration of mechanical or electrical systems while guaranteeing maximum protection. Also, this unique cable guide system allow for changes or improvements while maintaining the frame’s aesthetics.
9. Compact Geometry. Direct connection with the bicycle The new Quartz compact frame geometry ensures a fantastic fit and a true ergonomic position all while offering the rider increased responsiveness and stability.
5. Integrated 1.5” carbon headset Increased torsional stiffness

“The qualities of the Quartz model offer me so much comfort that I don’t want to get off the bike. It makes it especially easy to maintain cruising speeds on all types of terrain without losing performance along the way. This is a very responsive frame with great stability, creating a bike that has many possibilities, both for professional cyclists as well as for enthusiasts who want to improve”.
The carbon 1.5” headset, inspired by the G 6 line, is fully integrated within the frame. This allows for exceptional torsion stiffness and handling while providing the comfort and control expected from this frame category.
