    Here is a rare bird: 1997 Stevenson Psychosis

    I love this thing. I had another one years ago and sold it, which I regretted ever since. Never thought I would find another one. Gotta be one of my favorite bikes.

    It is a 1997 Stevenson 'Psychosis', made by Bill Stevenson in Olympia, Washington.

    Short wheelbase, bombproof chromoly frame. The back end gets 2.25 inches of travel. The Fox F80 was a nice upgrade over the Judy I had on it originally. The handling is super fast. The suspension design is really pedal-efficient.

    Wierdo drivetrain, 3x8.
    18/26/34x11-13-16-19-23-28-34-42. Yes, I use the 18x42 once in awhile. Odd set up to most people I am sure, but it works well for me.

    Lots of unusual features in the frame and the build. Hope you like the pictures. Thanks for looking!

    Wow. Beyond cool!

    So this is one you tracked down to replace the one you sold years back? That's awesome, great score!

    18-42?! That's like a track stand gear!

    The short chain stays would make it a great climber, and with that gear you could climb walls.

    Does the chain clear the chainring bolts by much on the 18t, and who the hell even makes them!

    Nice Kona as well, I see you have a thing for mixing colours (and you have a favourite seat as well). I miss those days when things came in more than just black.

    That thing is off the hook!

    Ya, it does climb well. The suspension design really keeps the rear wheel planted despite the short wheelbase.

    The 18t granny is a Suntour Type-A cog, mounted on a Mtn Tamer Triple adapter. There are 18t rings out there in 56mm bcd, but it is impossible to find them. The one I have seen was thick, and the bolt holes were countersunk so that the bolt heads did not interfere with the chain. I have a 19t in 58mm, but it required spacers to use because the chainring is thin and the bolt holes are not countersunk.

    I do have a thing for mixing colors.. Both the Kona and the Stevenson are variations on a mostly purple and yellow theme. Those Titec Ithy's titanium rail seats are incredibly comfortable. They do not have a lot of padding but they flex nicely. The Kona is a 27.5" wheel conversion.

    Thanks for the extra details about the Psychosis set up.

    I'm keen to hear more about the 27.5 conversion of the Kona though. Something I might do with a Lava Dome if the stays and cross braces are similar. Maybe start another thread and not hijack this one.
