I'd like to reframe my question - so I really really liked the quality and shifting feel of this XT front shifter, and for 10 bucks I think that would be an awesome upgrade if it worked. SO, if I can't graft it onto the bike with the TD-One FD, would it work with a Shimano FD-TY30 front derailleur? What I'm hoping is that the older XT front 3x shifters (again this one is SL-M770-A-L) would have the same pull ratio as the older low-end Shimano 3x FD's. I tried researching compatibility but only found conflicting information, hence turning here in case anyone knows. Thanks again.
