The objective for the G7 Disc was to maximize performance and rigidness of the frame at the same time as including disc brakes. It has been developed combining the computer analysis derived from tests performed in a wind tunnel and fluid dynamic tests performed by computer. This results in a frame with an innovative aerodynamic silhouette integrating disc brakes into the same aerodynamic.
It incorporates a BB386 bottom bracket proving a large space between the stays and giving the rear triangle high levels of rigidity and compliance. The seatpost and seat casing have been integrated into the frame. The steering post made form carbon incorporates the bearings integrated into a unique design.
Optimized Aerodynamic Transversal Section
To optimize aerodynamics to maximum levels and based on the G6 Pro frame, the R&D team identified the transversal sections of the frame that had the best fluid dynamics results and used them to strengthen them as much as possible in the new G7 Disc frame. The optimal geometrics of the rear triangle have been identified using the analysis of fluids on the frame. Because the brake is no longer situated in this area the R&D team has been able to find a much more aerodynamic and innovative transversal section.
Flat Mount Shimano
The incorporation of a 140mm disc brake at the front and rear, with Shimano Flat Mount technology has been a fundamental difference in the design of the frame. The rear part of the frame has been completely redesigned to support the forces and tensions produced by the new anchoring of the disc brakes that are completely different to those produced by conventional brakes.
Di2 Battery Incorporated into Seatpost
The electronic gear change is fully housed and hidden. Using a patent "clip" system inside the seat-post. It is discreet, lightweight, isolated from humidity and allows easy assembly.
The 12 mm Thru Axle provides the optimal dimension for greater rigidity and safety. It optimizes the position of the disc brake. Moreover, tools are not needed if the cyclist has to disassemble the wheel.
