Looks like a Mt Hood to me? Damn nice either way!! Clean, clean, clean! I love old made in the US mountain bikes. Trying to get an ANCIENT low production CW built up at the moment.
My Mt Hood. Sold it like a fool, before I moved three years ago. I just got told recently, that it was torn down, spray painted flat black, and made into a single speed hipster bike. From this, to worthless junk, in one idiotic day.
A Ross Mt-Hood was my first mountain bike in 1983 when I was living in Colombia and things like bikes where almost impossible to get (I got mine from a US marine, station at the embassy)
