A Google search on "Nicolas Arrequi" suggests that the correct spelling is probably "Nicoloas ArreGui"
I have no idea to tell you the truth. My source was a pamphlet written by Richard Hallett, then of Albuquerque. I also see that Richard Hallett was quoted on the CR page under Zeus where he says the founder was Luis Arregui, not Nicholas Arrequi. So, if someone knows for sure, let me know & I'll correct the entry in the Used Bike Buyers Guide. Lou Deeter, Orlando FL
