Hello to all, Hello Kim,
this is a low end Bianchi Frame, manufactured in the beginning of the '90s.
Bianchi made cheaper frames with Columbus SLX tubing, Brake cable routing on top of top tube, And no engraving steerer tube, like the Specialissima X4.
This frame were selling for ca 790 DM, today this is about 320 USD.
The frame finish is very raw, not like Spec X4.
This frame comes with an unicrown welded fork.
I have sold many of this frames in that time.
This was the time when Bianchi Germany was located Near Augsburg.
