I have a dura ace FD7400 front changer which came withthe original 6 speed SIS grouppo of 20 years ago. I wanted to pair it with dura ace 8 speed STI from a decade ago, but shimano says there's not enough cable pull. I put it together and it almost works, but I'm maybe 1-2 mm short. Has anyone gotton this combo to work with some strange cable mounting or something? If not I'll just buy a new FD on ebay! Recall that the DA 8speed rear deraillure could be made to work with other shimano shifters by mounting the cable differently. TIA.
