Sorry mate but I only scanned these 3.0 mountain bikes before selling the catalogue. But I think I do have a full 1991 catalogue (USA version) in PDF. If you're interested, send me your e-mail address in PM.
I ever got the USA catalog (I think, it the same on "www.vintagecannondale .com). I had this european cannondale 1991 catalog, but I lost it :cry:
The cover was black with a red autocad draw of a frame?
I bought my EST C'dale, one year later !
