Razesa, is a small but prolific workshop in the Basque country that built high end framesets for Zeus toward the end of Zeus's lifespan in the late 70s to early 80s.
When Miguel Indurain won the first of his five consecutive Tour de France victories in 1991, he was riding a bike considered by many to be the finest Spain had to offer. It was a Razesa. In 1992 and 93 the Spanish Amaya team rode white Razesa bicycles.
Razesa is still in business and thriving today.
