A final update. I ended up ordering a Problem Solver set of shims, 25.4-31.8 from my LBS who gave me a better price than I could find online. Installed this morning without a hitch and a 2 mile ride in a light rain. Of course I need a long ride to know but my initial impressions are it feels great and more natural to my body. I went from 110 to 90mm.This bike was built as a 58 and my other two roadies are 56s.
Still on the fence about a torque wrench. I asked my LBS mechanic about whether I needed a torque wrench due to the carbon steerer but he said not to worry as the Seven wound up fork with the aluminum sleeve is bomber. He's a Seven dealer as well.
Thanks Robert and Merlin for your great help!
