Razesa is a small builder from Navara in the North of Spain. The area has a great tradition in cycling and steel making.
The company produced the high end framesets for Zeus in the 70’s through the early 80’s, which is when this frame dates from.
As recently as 1992/93, the Spanish team ‘Amaya’ rode white Razesa bikes.
The frame has been resprayed and the bike rebuilt.
