If you liked the Passoni Fidia and its carbon-titanium weave, not to be outdone by the Italians comes a new bike company from Spain, Rancormance, that boasts basalt-fiber and carbon fiber hybrid construction.   The company claims that while basalt fiber has similar strength, weight, and stiffness characteristics as carbon fiber, it absorbs vibrations better.   Thus, basalt fiber is used in the top tube, seat tube, and seat stays for better comfort, carbon fiber is used in the head tube, down tube, and chain stays for better rigidity and power transfer.
