Paul Brodie started building at Rocky Mountain in ‘84 handling custom mountain bikes until 1986 when he started Brodie with his 114th bike frame built.
at the same time Rocky Mountain Bicycles were also handling a large amount of distribution for Ritchey resulting in a lot of nice Timberwolf’s and Timbercomp’s lurking around.
the two brand also had a loose collaboration on Toyo built “Ritchey Rocky” builds. Basically a Ritchey Ascent with a few Rocky emblems on it.
As far as I’m aware that’d be the main staples for higher end examples from the earlier days, at least here on the west coast? The explosion came a bit later with many more brands like Moulden, UFO, Off Road Toad, Dekerf, Ripe Pipe, Lavoie, Proctor Townsend, etc…
