they are about right on my 94 cannondale bote
Yeah 2 pinch bolts on the back of the fork then it should slide out! . . . . you may need a shim though (From 1'' to 1''1/ Just backdated will have these as well as other length steerers (Steel and Alloy), my forks cost me a furtune but their mint!
Thanks for the help and advice everyone. Within a few hours of posting here I have sourced not 1 but 2 sets of forks which should be great for building up both frames.
