The bikes that I have with 135 rear dropout seem to have ~45mm chainline to the middle cog of a 9sp cassette. Do you have one of the bb so that you can see where the midline between the two chainwheels will sit? I agree with Sidney though, 3mm is not much diff. That being said, I tried a 107 on a 9sp double chainwheel with 135mm rear (Kogswell P) and decided that 110 shifted better, I may have just adjusted better on the second setup.....(square taper un73) YMMV
