Anyone have any definitive info on how to install the S3 XX direct mount front derailleur on the 2011 S-Works Epic 29er frame? I have it mounted but want to make sure I have it correct before I put any signficant shifting force on it. Specialized doesn't have ANY info on the issue and I just want to make sure I get it correct. I was able to speak with tech support and they were unable to answer all of my questions. Thanks for the help.
