FeaturesFORM SmoothWall CARBON Custom Rocky Mountain FORM C13 High Modulus SmoothWall construction. 100% designed, engineered and tested in house by our R&D team to ensure the lightest, stiffest frame and the best ride quality. In 2011, we unveiled SmoothWall construction to the world with the introduction of the Element RSL, and since then, it has won unanimous praise for its incredible light weight and superior stiffness. Smoothwall construction is achieved by sculpting the inner surface of the frame as carefully as the outer, with the help of an inner mold, as opposed to the traditional air bladder. This results in no excess resin, fibers or filler, meaning no stress risers or extra weight.

The most important characteristic of SmoothWall technology is that it enables us to construct frames with the highest carbon layup density. SmoothWall’s super high fiber to resin ratio with maximum compression of the pre-preg carbon layers results in the lightest and stiffest construction possible. SmoothWall also allows us to use full length (uncut) fibers, yielding a stronger frame. This all adds up to one of the most sophisticated carbon frames in the world. Vertex RSL utilizes a precise carbon layup schedule, using multiple types of carbon weaves in specific locations to maximize stiffness and impact resistance while minimizing weight.
Vertex RSL

We were able to optimize the ride quality of Vertex RSL through our FORM Carbon design process. By carefully selecting the modulus and layup of the frame, we created a super light and stiff ride in an aesthetically beautiful package.
