Manta RS Pro


Experience, opportunity, innovation and technology collided to catalyze our new frame model, the Manta RS.  The Manta RS is a platform that leverages a patented, active suspension system at the rear wheel to enhance traction, power transmission and comfort to increase rider performance.  Like all Calfee frames and components, the Manta is hand crafted and painted in our workshop in Santa Cruz County.
