I still own one
I bought one in 1982 and have ridden it in races for 5 years. Even then I never saw somebody with the same frame.
I still own it and I just sent it out to have it repainted in its original colors because it is still a very nice bike to ride. I have it repainted because the paint was damaged too much, but it has no dents. So after repaint it will look like new again. Now I am going to use as my bad weather bike.
It actually handles much better than my 2008 BMC SLC01 because of the short wheel base. The bracket is also slightly higher than normal to allow you to continue pushing the pedals in a corner.
I'll post a few photo's when I've put it back together again.
