You're looking at a 1990 Rocky Mountain Metro - the first hybrid ever in Rocky's lineup. The hybrid became a very popular style of bike when people realized how great it was to have most of the speed of a road bike, but with the more comfortable upright riding position of a mountain bike.
You are looking at a 1985 Ritchey Rocky Mountain / Ascent. It is a 4130 steel frame with a 6-speed non-indexed drivetrain and an alloy Bullmoose bar.
It has both Ritchey and Rocky Mountain decals on it, but it was not made by Tom Ritchey, nor was it made by Derek Bailey, Chris DeKerf, or Paul Brodie.
I hope you're sitting comfortably, because we have lots to talk about here...
You're looking at a 1993 Rocky Mountain Stratos. The Stratos was Rocky's entry-level aluminium bike, debuting in 1989, made in Japan from 7000 series alloy. I think. There should be a decal about the frame tubes on the bike, but it's gone.
It's an interesting bike as Rocky put some extra effort into the parts spec, attempting to make this something more than just another hard tail.
I'm 80. I wrench more than I ride and I like it that way.
