One of a kind, do it all machine. This revolutionary race-platform guarantees superior performance.

24-16-02

Experience, opportunity, innovation and technology collided to catalyze our new frame model, the Manta.  Five years in the making, the Manta is a “race platform” that leverages a patented, active suspension system at the rear wheel to enhance traction, power transmission and comfort to increase rider performance.  Coupling manufacturing processes and technology we own with innovations by external business partners, the Manta is an extremely flexible module.  Like all Calfee frames and components, the Manta is hand crafted and painted in our workshop in Santa Cruz County.
