i had the same issue with my frame. i doubt you'd be able to get a pre 1991 derailleur hanger for a cannondale. fortunately the hangers from 1991 onwards fit except for being a bit loose when mounted. i solved it by cutting a "spacer" out of a can.biketraum":1jiz1rnf said:Hi,
I'm looking for a rear derailleur hanger for exactly that bike.
Has anybody an idea, where I could get one?
My SM 1000 is hanging around for some years now an I would like to rebuild it again.
Thanxs.
