Oh wow that’s cool.One of the guys at ratrodbikes.com was a welder for ventana. He's shared a few of his bikes...
"Ventana started out steel but switched to aluminum. They did build a steel coupler tandem that was a work of art.
Their history is a bit on the secretive side. They built bikes for other companies also. It was always hush, hush. A few years back they were building Fat Chance frames. I happen to stop by one day and met Chris Chance. Waaaay back in the late 90s they built frames for a very large bike company. Most of those were built for the TDF."
