I had a test ride of a Stratos back in 1988 or 1989 at a place in Harrow I think called Cycle Systems. I can remember the chap telling me it was a prototype. I ordered a white spider II on the same trip to the store and still have it in storage. Hopefully one day I'll get a respray and rebuild although it's not in that bad condition to be honest as I'm a bit of a light weight with my occasional riding.
It was finished in the same red spatter paint on a white background as the prototype. One thing that I always regreted was the fact Roberts somehow left off the front CR decal. You would have thought they would have noticed that before firing the frame or what ever process it goes through. I'll take a pic in the summer when I get the old girl out for a spin.
